Troubleshooting cases
29 branching cases. Each one starts from a symptom. Wrong branches say why they are wrong and send you back.
- A PSTN call connects. The caller hears the carrier. The carrier hears nothing.
- A lobby phone dials a national number and gets reorder immediately.
- A laptop off the VPN cannot register. Desk phones in the office are fine.
- Monday morning, nobody outside can sign in. A few internal services warn about tomcat.
- A branch user dials 911. The call connects. The PSAP calls back and reaches a headquarters receptionist.
- A forwarded call reaches Unity. Every caller hears the company greeting.
- Users dial a national number and get reorder. Four-digit calls still work.
- A translation is supposed to turn 9.1 plus ten digits into +E.164. Callers hear dial tone again, then reorder.
- The caller sits in queue, then the script selects an agent. The desktop shows Reserved. The phone does not ring.
- Two outbound dial peers share a destination pattern. About half the calls use the expensive peer.
- The WAN is back. Branch phones still show registered on the router.
- A Jabber client outside connects. Neither side hears anything.
- A user in a two-cluster company signs into the cluster that does not own the directory number.
- The user is signed into Jabber. The desk phone is unregistered in RIS.
- WAN down. Branch phones are on the router. Webex Calling users in the same company do not ring.
- A lobby phone reaches the CEO's directory number. It should not.
- After a class-of-service cleanup, the lobby cannot dial emergency. Executives still can.
- A national call fails. The CUBE debug stays empty.
- The same phone dials out. Inbound to its directory number from the carrier fails.
- A PSTN call that used to connect now fails after the SIP profile was set to Mandatory.
- collab-edge is correct. Outside Jabber still will not start MRA. Desk phones are fine.
- Jabber on the iPhone works while the app is open. After the screen locks, calls vanish. Desktop Jabber is fine.
- DNS is published. A new X14.3 pair has no MRA registrations.
- The lobby cannot dial the international route pattern. A four-digit code on the same phone can.
- A phone that just appeared in the cluster can dial national numbers. Nobody built a line for it.
- The pilot matches. Three phones ring. The fourth, which is first in the line group, stays dark.
- A user dials the pilot from their own phone and hears the opening greeting.
- DNA shows one calling-party mask. The SIP trunk trace selected another.
- Every hunt member pressed HLog. New callers still sit in queue and hear music.
