Hello everyone,
I have an issue with inbound calls intermittently disconnecting when answered. Here's information about the system:
When answering a call, the phone will display "Media Error" and the call will drop. This happens to only a few calls a day, and the caller will call right back in and can be answered. I have not been able to find a pattern for the disconnected calls. This issue has been happening for a long time now, so I'm not sure when it started. Yesterday I turned verbose logging on and ran packet captures for 15 minutes at a time till the issue happened. Attached is the activity log from that time/call, I've scrubbed it of sensitive information, so phone numbers and IP's are changed but still readable. I'm hoping someone will be able to tell me what caused the call to hang up. I'm not sure I'm reading the packet capture correctly but it looks like the hang up is coming from the 3CX system local host 127.0.0.1
Thank you!
