[Freeswitch-users] SIP timer at 900 seconds?

[Avi Marcus]

I see two recent calls from FreeSWITCH that end at 15 minutes:

billsec: 904.1, hangup cause: MANDATORY_IE_MISSING
billsec: 901.3, hangup cause: MANDATORY_IE_MISSING

My system is hanging up the call.

Is there some sort of SIP timer? I don't have a SIP trace to see what
happened.

The remote carrier said:
>However I'm unsure of what the issue is you are reporting as the BYE
simply came from your side?
>This is not something we are familiar with or why your server did or
requires this.
> Reason: SIP;cause=488;text="No answer to offer".

Any suggestions?
