Cisco 7940 Music on Hold

I have an ISO based 4.4 system that is up to date. I have uploaded a music on hold file, but when I use a Cisco 7940 and put a call on hold, it doesn't seem to play the music on hold. Is there an incompatibility between the 7940's and SipXecs in regards to music on hold, or can you point me in the direction of how to tech the problem? Thanks.

Cisco phones do not have the capability to support music on hold as defined
in http://tools.ietf.org/html/draft-worley-service-example-04 which is
what sipX uses for music on hold.

if you get calls in through sipxbridge (internal sbc) you can get MoH for
external calls (sipxbridge can inject MoH)... but will not work with
audiocodes gateway / internal phone to phone.

Interesting, on some Linksys SPA942 I had music on hold working on
phone-to-phone, and phone to gateway (Epygi). However, can not get it
working with Phone-to-Audiocodes. It did play Audiocodes noise making
Music-on-hold tone though - but it was a bit obnoxious. Not sure if they
operate the same as the 7940 phones.



It's great FUD to know that Cisco phones don't work with some standard SIP
implementations.

SPA942 supports the correct MOH uri method.

Perhaps the epygi does too. Most gateways (audiocodes, etc.) do not (yet).

cisco's sip uses the old hold method (0.0.0.0) which is the 1980's style of
MOH, but then they built their phones more for call manager and sip as an
afterthought or second tier way of doing this for those models.

sipxbridge's MOH is that it anchors all the media so it works. Gateways
(audiocodes/patton, etc.) do not have a MOH URI that points to sipx. Some
SBC's do. Internal calls require the UA to support this MOH URI method. In
the end, the limiting factor is not the gateway, SBC or sipxbridge, it's
the UA. The UA must support it in order for it to work in all call flows
(trunks, gateways, internal). If the UA doesn't support it, it ain't gonna
happen.

Todd, there isn't any FUD about it. They fall down on:

RFC3261 - REFER, headers, content-types, record-route
RFC3263 - SRV and NAPTR for SIP
RFC3515 - REFER
RFC3891 - Replaces
RFC3856 & RFC4479 - Presence
RFC5589 - REFER and Replaces

I got tired of reading after finding those, I'm fairly confident there
are more the firmware does not support. :)
