I have a PBXact system, and it was working fine with all extensions. I have two extensions that are Yealink DECT phones, again that worked well for a long time. I am not sure if it the a module update, or a firmware update to the phones, but now both DECT extensions can make calls just fine, but incoming calls no longer ring on the phones.
So I thought let’s go look at the log and figure this out, and I see plenty of the following errors in the full file, which I suspect is the cause of the extensions no longer ringing:
[2021-08-13 14:17:03] ERROR: res_pjsip.c:4464 endpt_send_request: Error 120022 'Invalid argument' sending OPTIONS request to endpoint 260 [2021-08-13 14:17:04] ERROR: res_pjsip.c:4464 endpt_send_request: Error 120022 'Invalid argument' sending OPTIONS request to endpoint 261
I thought I would just put the extensions in debug, but it looks like under pjsip I don’t have the same option to do that like I did with sip. Will have to go look up how to debug pjsip I suppose. If anyone has run into this one, and can toss me any pointers it would be helpful…
