Number Porting & Cutover

Color-coded sequence: Source PBX → Plan → Cutover → Webex. A packet moves along the arrows. Reduced motion keeps every step visible.

A port moves a number from the losing carrier to the winning carrier. For Cisco Calling Plans, Control Hub is where the order, the letter of agency, and the day-of checks live. The date is not real until the losing carrier returns a firm order commitment. Port-out uses a different menu than port-in.

01 · Executive summary

Five lines, then why it matters

Slamming is forbidden. Cisco does not change a telephony provider without written consent of the authorized account holder. [cite:1]
Same-account numbers port together even across orders. Distinct account information means separate orders. Toll-free is a separate order from DID, and the guidelines say US or CA only. [cite:1]
Ask for at least five business days, or two to three weeks for a larger port. The earliest request can be 1–35 business days. The latest is 30 days from submission. Activation is requested between 9 a.m. and 4 p.m. on business days and is not guaranteed until FOC. [cite:1]
Wait at least 15 minutes after FOC, or 30 minutes for a project or complex port, before you call the port failed. Then check Control Hub, then open PTS. [cite:1]
In the United States and Canada, porting a number ports Calling services. It does not port messaging. [cite:3]

Why it matters. Cutover day fails when someone disconnects the old carrier at submit, edits the order after FOC inside Control Hub, or treats a port-out menu as the port-in menu.

03 · Core concepts

The guidelines, quoted as a table

Rule	What 01sijg prints	Cite
Definition	Number porting transfers existing numbers from the losing carrier to the winning carrier. Country processes differ. The page is general.	[cite:1]
License	One license means you can port only one number. Ports cannot exceed licenses purchased.	[cite:1]
Proof	Current bill or invoice, dated within 30 days, plus an LOA. Some LOAs are eLOAs autofilled in Control Hub. Others are completed, signed, and uploaded.	[cite:1]
Account grouping	Numbers on the same account port simultaneously, even across orders. Distinct account information goes on separate orders.	[cite:1]
Toll-free	Separate orders from DID. The guidelines say US or CA only.	[cite:1]
Pending order	A pending order on the account blocks more numbers. If the BTN ports, a non-ported number becomes the replacement BTN.	[cite:1]
Extra services	When the number ports, the original installation ceases, including broadband or alarms on that line. They may not come back.	[cite:1]

Gotcha. The Complex column is headed “Any of the following,” and its first cell is “> 1 TN.” Standard is “1–50 TNs.” This room does not invent which column wins when both could be read. Quote the header. [cite:1]

Before FOC and after FOC

When	What you may do	Risk the article names	Cite
Before FOC	Change or cancel in Control Hub.	The article says no risk of the numbers porting or of service impact.	[cite:1]
After FOC	You cannot modify the order in Control Hub. Open PTS.	72 hours minimal, 48–72 low, 24–48 moderate, under 24 hours high. May vary by country.	[cite:1]
Snapback	Emergency restore back to the losing carrier. Open PTS immediately.	Window 1–48 hours depending on carrier and country. Includes slamming.	[cite:1]
Day of FOC	Numbers should already be assigned to users or features. Hardware ready. Activation is automatic.	Allow 15 minutes, or 30 for project or complex, before you declare failure.	[cite:1]

Note. Get Started also says the FOC date can be two business days later from the submission date, and defines FOC as the date the losing carrier states it releases the number. Do not merge that sentence with the guidelines’ 1–35 day earliest range. Teach both. [cite:3] [cite:1]

Port out is a different screen

Direction	Menu the article prints	Behavior	Cite
Port in, support case	Calling → PSTN → Orders, then Open a Cisco Calling Plans support case. If you have no order, the article says you can start Order New Numbers and stop once the link appears. The PSTN support mailbox named in the cited article is the alternate.	PTS is 24/5, aims to respond within 2 hours, best effort. Losing-provider support on the day is generally 9 a.m.–4 p.m.	[cite:1]
Port out	PSTN & Routing → PSTN Orders. Filter Order type Port out and status Pending.	Auto-accept after one business day. The number stays active until the gaining carrier finishes. Then it is deleted. If assigned, the article says it is unassigned and then deleted. Reject moves to Reject Pending, then Rejected.	[cite:2]
Location main number ports out	Same port-out article.	Assign a new main number to avoid calling disruption.	[cite:2]
Plan cancelled	Service cancellation section.	You must port out to keep the numbers. Unported numbers are released after a reasonable period. Cisco cannot guarantee availability after release. The article does not print a day count.	[cite:1]

Glossary, map, sisters, edges

Mini map of the neighbors named on this room’s sequence. Orientation sketch, not a new product claim.

Glossary

Losing carrier: The current PSTN provider. The winning carrier is the provider that receives the number. [cite:1]
FOC: Firm order commitment. The losing carrier’s date and time. Requested dates are not confirmed until FOC. [cite:1]
LOA: Letter of agency authorizing Cisco to act for the customer. Some countries use an eLOA filled in Control Hub. [cite:1]
BTN: Billing telephone number. If it ports, a non-ported number is designated as the replacement. [cite:1]
Snapback: Emergency restore of a number to the losing carrier, inside a 1–48 hour window. [cite:1]
PTS: Cisco PSTN Technical Support for Calling Plan number orders, porting, and related questions. [cite:1]

Cisco Calling Plan license	The count that caps how many numbers you can port.	One license, one number.	Purchase before the order.	A port list longer than the license count.	[cite:1]
Location	Where a Calling Plan is enabled before port-in.	Get Started says enable the plan for the site first. The deployment guide says ordering and porting for Cisco Calling Plans starts in Control Hub once the location exists, in countries where the plan is available.	Do not invent the country list.	A port started before the location exists.	[cite:3] [cite:4]
CCP or premises PSTN	Numbers added in Control Hub, and they can stay inactive until assigned.	That add is not the Cisco Calling Plan port wizard.	Implement article number step.	Treating an inactive add as a completed port.	[cite:5]
Business texting	Separate from the Calling port in the US and Canada.	Get Started says only Calling services port, then points at Enable business texting.	After the Calling port succeeds.	Expecting SMS to move with the DID.	[cite:3]
Reseller	A provider that bills you while an underlying carrier owns the number.	Port data must match the underlying carrier, not only the reseller bill.	Ask the reseller for the carrier record after a rejection.	Copying the reseller invoice fields and stopping.	[cite:1]
Emergency callback	Basic emergency wants a customer-owned +E.164 on the location.	If the main number ports out, assign a new one.	Port-out article, then the location.	A location whose main number has left.	[cite:2]
Identity	The authorized account holder signs the LOA.	Get Started says only an authorized account holder with admin rights signs.	Name and job title in the wizard.	A signer the losing carrier does not recognize.	[cite:3]

06 · Config

Paths you can cite

Enable the Cisco Calling Plan on the location before a port-in. [cite:3]
Create the draft in Control Hub. Upload a bill from the last 30 days. Sign the LOA, or use the eLOA when the country uses one. [cite:1]
Review every number. After submit, numbers cannot be added or changed. Toll-free is its own order. [cite:1]
Assign the numbers to users or features before the FOC time. Leave them inactive until activation completes. [cite:1]
On the day, wait 15 minutes, or 30 for project or complex. If they still fail, check orders and number status, then open PTS from Calling → PSTN → Orders. [cite:1]
To port out, open PSTN & Routing → PSTN Orders. Accept, or reject with a reason. If you do nothing, the request is accepted after one business day. [cite:2]

Warn. Do not disconnect the losing carrier at submit time. The guidelines say the numbers stay active with that carrier until the port is complete and verified. [cite:1]

08 · Troubleshooting

Ten port failures

Symptom	Likely cause	Evidence	Fix	Cite
The second number on a one-license subscription is rejected	Ports cannot exceed licenses.	License count versus the order.	Buy the license or drop the number.	[cite:1]
Account number mismatch	The field does not match the CSR. For some carriers the account number is the BTN.	Get Started rejection table.	Update the account number and resubmit.	[cite:3]
A second order on the same account is rejected	A pending order blocks more numbers.	Guidelines pending-order bullet.	Finish or clear the pending order first.	[cite:1]
BTN rejection after an inactive-number rejection	Losing carriers decline one reason at a time.	Rejection section.	Clear with the losing carrier, update Control Hub, resubmit. Rejections can reset the SLA.	[cite:1]
Reseller invoice fields still fail	The underlying carrier record is the one that must match.	Resellers section.	Ask the reseller for the carrier’s data.	[cite:1]
Control Hub will not edit the date	FOC has already been received.	Order status.	Open PTS. Changing a confirmed date is discouraged.	[cite:1]
Numbers are silent 10 minutes after FOC	The wait is 15 minutes, or 30 for project or complex.	Clock versus order type.	Wait, then check configuration, then PTS.	[cite:1]
A number ported without consent	Slamming.	No LOA from the authorized holder.	Open PTS immediately for snapback.	[cite:1]
Port-out vanished overnight	Auto-accept after one business day.	PSTN & Routing → PSTN Orders.	Reject before that day if the port should not proceed.	[cite:2]
Calls break because the old carrier was cancelled at submit	Disconnect is step 7, after verification.	Losing-carrier account status.	Keep the numbers active until the port is verified.	[cite:1]

09 · Self-question ladder

Twelve rungs

L0What is a port?

A transfer from the losing carrier to the winning carrier. [cite:1]

L1What two documents prove you may port?

A bill from the last 30 days and an LOA or eLOA. [cite:1]

L1How many numbers does one license allow?

One. The port count cannot exceed purchased licenses. [cite:1]

L2When is the requested date real?

When the losing carrier returns an FOC. Until then it is a request. [cite:1]

L2What happens to numbers on the same account?

They port together, even if they were typed on different orders. [cite:1]

L3How do you prove you can still edit the order?

FOC has not arrived. After FOC, Control Hub edits stop and PTS is the path. [cite:1]

L3What evidence shows a port-out was ignored?

One business day passed on PSTN & Routing → PSTN Orders. The article says the request is then accepted automatically. [cite:2]

L4Why are there two menus?

Port-in support is Calling → PSTN → Orders. Port-out processing is PSTN & Routing → PSTN Orders. The articles print both. Do not collapse them. [cite:1] [cite:2]

L4What does a US port not move?

Messaging. Get Started says only Calling services port in the United States and Canada. [cite:3]

L5Which order-type cell will you not “fix”?

Complex is headed “Any of the following” and starts with “> 1 TN,” while Standard is 1–50 TNs. Quote both. Do not invent precedence. [cite:1]

L5What day count will you not invent?

How long “a reasonable period” is before unported numbers are released after Calling Plan cancellation. [cite:1]

L3When may you cancel the losing carrier?

After the port completes and you have verified it. [cite:1]

10 · Lab

A paper lab. Do not submit a port against a number you do not own.

Goal: place eight events on the correct side of FOC, and name the menu.
Prereq: articles 01sijg, wsk3m9, and nousk9ab. No live order.
Step 1. One license, three DID. Expected: the guidelines allow one number.
Step 2. Edit the due date after FOC inside Control Hub. Expected: not allowed. Open PTS.
Step 3. Numbers fail 10 minutes after a simple FOC. Expected: the wait is 15 minutes.
Step 4. A port-out sits in Pending for a business day. Expected: auto-accept.
Evidence: the two menu strings, written side by side.
Break it: disconnect the losing carrier at draft time. Recovery: the article says keep service until verification.
Reflection: which Complex-versus-Standard cell you refused to merge.

11 · Quiz

Twelve questions

Q1MCQ

Who is the losing carrier?

Answer

The current PSTN provider. The winning carrier receives the number. [cite:1]

Q2MCQ

How many numbers can one license port?

Answer

One. Ports cannot exceed licenses purchased. [cite:1]

Q3MCQ

How recent must the bill be?

Answer

Within the last 30 days. [cite:1]

Q4Scenario

Two orders list numbers from the same losing-carrier account. What must happen?

Answer

Those numbers port simultaneously. [cite:1]

Q5MCQ

Where do toll-free numbers sit relative to DID orders?

Answer

On a separate order. The guidelines say US or CA only. [cite:1]

Q6MCQ

When is a requested port time confirmed?

Answer

When FOC arrives. The request window is 9 a.m.–4 p.m. on business days and is not a guarantee. [cite:1]

Q7Scenario

You need to move the date 10 hours after FOC. What is the risk band, and where do you go?

Answer

Under 24 hours is high risk. You cannot edit it in Control Hub. Open PTS. Bands may vary by country. [cite:1]

Q8MCQ

How long do you wait before declaring a project port failed?

Answer

30 minutes. A non-project port is 15 minutes. [cite:1]

Q9MCQ

What is the port-out menu?

Answer

PSTN & Routing → PSTN Orders. Auto-accept is one business day. [cite:2]

Q10MCQ

What does a United States port move?

Answer

Calling services. Not messaging. [cite:3]

Q11Draw

Name the Complex column header and its first cell. Do not reconcile it with Standard.

Answer

Header: Any of the following. First cell: > 1 TN. Standard remains 1–50 TNs. [cite:1]

Q12Scenario

The Calling Plan is cancelled and nobody ports the numbers. What does Cisco guarantee?

Answer

Nothing about availability after release. Release is after a reasonable period. No day count is printed. [cite:1]

13 · Interview

Oral answers

30 seconds. Porting moves a number from the losing carrier to the winning carrier. Cisco will not do it without the authorized holder’s written consent. You need a bill from the last 30 days and an LOA. The date you type is a request until the losing carrier sends an FOC.

2 minutes. One license ports one number. Numbers on the same account move together. Toll-free is a separate order, and the guidelines limit that sentence to the US or Canada. Keep the old service up until you have verified the port. Before FOC you can still change the order in Control Hub. After FOC you open PSTN technical support, and the risk bands run from 72 hours down to under 24 hours. Snapback is an emergency restore inside 1 to 48 hours. On the day, wait 15 minutes, or 30 if the order is project or complex.

30 seconds, menus. A port-in support case starts at Calling, PSTN, Orders. A port-out is under PSTN and Routing, PSTN Orders, and it auto-accepts after one business day. If the location main number leaves, assign a new one.

2 minutes, what else moves. In the United States and Canada the port moves Calling, not messaging. Broadband or an alarm on that line can cease with the installation. A reseller bill is not enough if an underlying carrier owns the number. When the Calling Plan itself is cancelled, you port out to keep the numbers. Cisco does not promise you can get a released number back, and it does not print how many days “reasonable” is.

What you will not say. You will not merge the Complex column with Standard. You will not invent a Cisco Calling Plan country list. You will not treat Get Started’s “two business days” as a replacement for the guidelines’ 1–35 day range.
