<p class=MsoNormal>Hi<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have an AudioCodes GSM (SIP) gateway connected to a 2821
H.323 gateway via SIP which is then connected to CUCUM via h.323<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Regular outbound calls work fine. CUCM sends all 0.@ calls
to the H.323 gateway and then the gateway matches mobile phones call to a SIP
dial-peer and sends the call to the AudioCodes GSM gateway.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The only problem is when a call via the GSM gateway gets added
to an adhoc conference, it gets dropped/disconnected all together after about
10 seconds. If I configure the H.323 gateway to require an MTP then the calls
don’t get dropped, however any CUVA (Video Advantage) user who makes a
PSTN call gets a message on their phone saying “Video Bandwidth
Unavailable”. The CUVA doco says this is because an MTP is being used and
MTP’s don’t support video.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The only MTP’s in my network are the default ones configured
in CUCUM.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any ideas on how I can get the calls via the GSM gateway not
to drop when added to an adhoc conference without enabling an MTP on the
gateway in CUCM? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Or is there a way to have PSTN calls for CUVA users not show
the “Video Bandwidth Unavailable” message when it’s clearly
an audio-only call when an MTP is enabled for the gateway? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Nick.<o:p></o:p></p>
