Hi Experts, we use Cisco SPA IP phone without problem. Recently we encountered an issue with CANCEL messages with REASON CAUSE.
The SPA doesn't understand this message and so, in case of no response, the call never stops.
If in the CANCEL message there isn't any REASON CAUSE the call is stopped normally.
Can SPA 30x supports RFC 3326? Can you implement this feature in the next firmware or fix misunderstanding messages?
Thanks in advance.
