[asterisk-dev] SIP to SIP unhold and no voice

[Aragon Gouveia]

Hi,

I've come across strange behaviour that I'd like to fix.  I have an asterisk
1.2.9.1 setup with a number of SIP phones ("friend" in sip.conf) connected
to it.  If a SIP phone calls another one and the call is placed on hold by
either phone, the phone that was placed on hold does not receive anymore
voice from the other phone after the call is taken off hold.

I've reproduced this with SNOM360s, SwissVoice IP10s, SJphone, and Xlite. 
Is this an Asterisk bug and, if so, is there a fix?


Thanks,
Aragon
