Disconnect Cause Code - 706(SIP)

[adrian-morris]

Hello,

We were using a Cisco codec pro to connect to a Teams call today using the SIP details provided by our cisco CVI integration with Team when it was disconnected unexpectedly. The Disconnect cause type is listed as "RemoteDisconnect" with the Disconnect cause code noted as "706 (SIP)". At the same time the codec disconnected from the call the other remote participant disconnected from the call.

It seems like the call closed for everyone and ejected all users but we're not sure why. What does disconnect cause code 706(SIP) indicate?

Thanks

A 7XX series code is not a standard SIP cause code. Standard SIP messages are in the range of 1XX to 6XX. To help you diagnose the problem, it would be helpful to see the entire SIP exchange of messages for the call if that is possible.

When I have seen 7XX series codes related to SIP it has been a vendor-specific (custom) code that a developer injects to indicate things like a problem with the SIP stack. (That's just one example and not related to your issue.) So you'd need to contact the organization that sent the 706 and ask them what it means for them.
