RE: MOH on Cisco phone 7941

MOH is generated by the media resources, not by the phone, so it seems that
7941 is not playing it and 7961 is playing it well. What is the codec that
is used to generate MOH stream? When you place 7961 on hold and hear the
MOH, hit ?? and see what the codec is. 7941 will only support g.711u and
g.729.

The other issue might be a multicast routing, and there is not enough
information to calculate the answer.
 
Also, is it a SCCP or a SIP phone (7941) ? The SIP load will not support
G.729 annex B. For that a hardware transcoder is required to support G.729
annex B out the H.323 trunk.

Subject: MOH on Cisco phone 7941

Hi Guys

    I was configuring the lab for media resources at CUCM 7. One thing make
me
frustrating is MOH didn't work at Cisco7941,but did work at Cisco7960.

    When I press "hold" button, MOH on 7941->7960 was working, 7941->7941
not
working, 7961->7941 not working, 7961->7961 was working. Device pool and
MGRL
are the same. Any idea ?

Many Thanks,

Tortle
