Can no longer make outbound or inbound calls?

JBrav0 — Thu, 18 Jan 2024 20:08:32 GMT

Suddenly out of nowhere we stopped being able to make outbound calls and when we call in to our organization the call (from the cellphone not our IP phones) will ring for 2 seconds and then drop.

I am able to ping to our Cube? I'm not familiar with Telecom terminology, so I apologize for that. But we are using a Ciso ISR4331/K9

and when I look at the logging it logs calls coming in but has the errors

8422: Jan 18 19:55:34.204: //4294967295/xxxxxxxxxxxx/CUBE_VT/SIP/FSM/SPI-State-Change: Current State = STATE_NONE, Next State = STATE_IDLE, Current Sub-State = STATE_NONE, Next Sub-State = STATE_NONE

8439: Jan 18 19:55:34.876: //4294967295/xxxxxxxxxxxx/

No changes where made it just happened suddenly.

Any help would be appreciated.

A disconnect cause code of 38 indicates "Network Out of Order". Since you are able to see the calls coming into your router from your service provider, that is unlikely to be the problem. The issue is more likely the connection between your router and CUCM. The first thing I'd do is reset the SIP Trunk in CUCM. A change may have been made to a related/dependent item in CUCM (such as a device pool, region, etc.) that would require a reset of objects that use that item. So a change elsewhere in CUCM might require a reset of your SIP Trunk.

Even if no changes were made, a reset of the SIP Trunk might resolve the issue.

Try that. Let us know if that fixes the problem.

Thank you for the help, as it turns out the device stopped being able to report to Cisco Smart license so the SIP feature just stopped working. I was able to get support to reset it for a temporary trial (30 days) So I had time to get it all straiten out my licensing team.

Advice you to update IOS to a version that doesn’t have the caveat of closing down the SIP service in the event of no acknowledgment from Smart Licensing is received in the allotted time period. Version 17.9.4 is a very stable and reliable version that is commonly used by many. For additional information see this community post. ISR4300 SIP Service Disabled

The defect for this is CSCvz82168 It has a note stating from with version of IOS where this do not happen.
