SIP notify SIP 500 Error

Hello,

we are experiencing a lot of problems with BLF using our SoundPoint IP6XX series.

BLF feature randomly stop working with the phone replying with a SIP 500 Internal Server Error message after a SIP Notify messagge.

Our SIP PBX Architecture is composed by a SIP Proxy running Opensips load balancing on 4 Freeswitch server.

 

We already tested the following firmware release:

4.0.9

4.0.10

4.0.11

 

But in all cases phones' behave in the same way.

Please find attached a pcap trace with 4 call on the same monitored extension on a soundpoint SPIP 650.

The first 3 calls are fine (BLF correctly blinking green on ringing)

The last call fails (BLF not blinking).

 

We are waiting for a feedback since we have many Polycom running the same issue.

 

Thanks

Regards

 

Francesco

Hello Francesco,


welcome back to the Polycom Community.

In this reply => here <= to the same / similar question I had already advised you to contact your Polycom reseller back in 2015.

 

In addition most of my replies to your other post's did not get marked as a solution provided if they did.


Without this they are not flagged and cannot help other users to find a solution quicker.

 

Please work with your Polycom Reseller so they can raise a ticket for you as we need more than a wireshark trace.


In order to raise a support ticket you need to work with your Polycom reseller as they need to do this for you. In case this is some sort of an Internet discounter please post your phone's MAC address so I can look up who would be able to support you.

 

I assume these phones are out of warranty so you would have to Pay per incident.

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

Best Regards

Re: SIP notify SIP 500 Error

Hello Steffen,

thanks for your quick feedback.

 

Since BLF issue have never been fixed on polycom phones, I can not mark your older replies as solved.

Anyway I confirm that I forgot to mark other issues (phone provisioning) and I just did it. Sorry for this.

 

Unfortunatly this samples are all of out of warranty, I'm going to provide you a mac anyway just to know who can help us in solving the issue.

 

What it seems to me is that this problem is not related to a particular sample. I suppose that there is something related to sip notify mechanism, maybe cseq values interpretation. I think it might be solved only with a fw fix.

I remember we worked together on a SIP670 problem related to sip notify that causes phone reset. You sent us a test phone and find a fix included in UCS 4.0.8.

We are going to buy some new VVX samples but we want to be sure that BLF works fine as it is for other brands we deployed on customers.

 

Thanks

BR
