VVX310 Invalid SIP Header

FreePBX stated:

 

This doesn't appear to be a FreePBX issue. It looks like you have an invalid SIP header which is causing the error. If you are seeing this repeatedly, you may want to open an issue... they suggest Digium but I thought I should post here and ask.

 

As reported here:
http://community.freepbx.org/t/pjsip-driver-error-messages-in-logs/28085

and here

http://issues.freepbx.org/browse/FREEPBX-8986

 

Running FreePBX 12.0.45 Asterisk 13.02 and fully updated, we have a few PJSIP extensions created and a single VVX310 physically connected. Our logs are full of errors that keep rotating about every 30 seconds when the phone is logged in. Not sure what to do but don't want to add any more phones yet or the console will become unusable for us.

Re: VVX310 Invalid SIP Header

Hello OPTN,

welcome back to the Polycom Community.

Not really sure where it was suggested to come here but if you require support you need to go via your Polycom reseller.

 

Looking at the snippet it looks the phone is trying to subscribe to something. This could be a BLF / Buddy or even voicemail but without any additional information very hard to guess.

 

As mentioned above this needs to be looked at by our support team and only your Polycom reseller can raise a ticket for you.

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards

Steffen Baier

Re: VVX310 Invalid SIP Header

Thanks for the reply Steffen. In looking at the errors log your correct in that the two extension errors seem to be related to entries we have created in the FreePBX server but the syntax error seems to be unrelated to anything else we have done. The other truly siginificant item about this whole problem is that we decided to change from the PJSIP driver back to a regular Channel SIP driver and with no other changes the error messages went away. I'm not sure if that points me to an Asterisk issue or an issue on the phones and how they handle the driver.

 

Your help is appreciated.
