Disconnect on hold / transfer after firmware upgrade to V8.7.5.35

After upgrading to the latest firmware 8.7.5.35 calls drop immediately when pressing Hold, Transfer or line keys. Happens on snom 320 and snom 370, with inbound calls only. Hold / transfer works just fine on outbound calls. 


On the pcap trace it appears as if snom sends a BYE request.

Here the solution from the ticket:

Snom Support:
There is / was a bug in older Asterisk versions that causes this behavior.

Please try to upgrade your version or disable video codec offer.

Hello everybody,


does anyone know hot to disable "video offer"? We have the same issue with several phones. Greetings

If its asterisk you should use videosupport=no in your general config or extension


If its other PBX you should ask your vendor
