This should be posted in the user forum. I suspect that you are
encountering a classic re-invite failure due to codec renegotiations. I
would take a look at the packet echange and see if your gateway tries to
change codecs between the hold attempts.

I am having an issue with version sipXconfig (4.4.0-
2011-03-21EDT13:50:34 swift) where the call is disconnected when put
on hold twice.
Scenario:
We have a cisco 2811 ver IOS15.1 with and ISDN PRI and using it as a
sip gateway to SipXecs.
User calls in from PSTN
Call is answered.
Answering user places PSTN call on hold.
(MOH is invited but not heard by PSTN user)
Answering user resumes call, now MOH is heard along with the voice.
Answering user places PSTN call on hold again. MOH is not invited again.
4 seconds later, the call is disconnected.
It seems that cisco 2811 disconnects the call because it thinks its a
mute call after the second on hold.
Also, in SipXecs and on the cisco. The ~~mh~~@ is still active for
about 5 minutes.
This did not occur on version 4.2.1.
Here is the pertinent cisco config:
voice call carrier capacity active
voice rtp send-recv

Does anyone have any ideas?
