Phone will not stop ringing

[aberry]

Having an intermittend problem with an 'unsupported' IP phone. Every once in a while a phone will get stuck ringing. The only way to fix the issue, is to either reboot the phone, or call voicemail and force a call on the line. Here is the verbose log from the call that caused the neverending ring:

I do notice the line in bold, but am not sure what to make of it yet. Has anyone else had a problem like this?

Thanks, TJ

One item that I noticed is :
02-Oct-2015 15:33:50.623 Endpoint Extn:3891 has added contact <sip:[email protected]:5060> for device Dev(586):[sip:[email protected]:5060;user=phone / 3891]
02-Oct-2015 15:33:50.623 [CM504001]: Endpoint Extn:3891: new contact is registered. Contact(s): [sip:[email protected]:5060 / 3891]

This was some 20 seconds into the call, so am uncertain if the phone was into its normal registration or if it had some issue that caused it.

I also noticed that the same extension had IP 172.26.102.20 (To: <sip:[email protected]>), but I assume this to be the 3CX server given that when the call went to Vmail, the VM extension was also on that same IP.

You might want to look at the extension settings and see how the settings for re-invite and replace headers are set and then do some testing by toggling same. I do not know that this will help, but possibly?
