MOH for third party sip phones

[iptsupport]

Hello , 

I using CUCM version 9.1.1.2000-5  . 

Does this version support MOH for third party sip phones ? 

Thank you

I think yes b/c I can listen to default MoH playing to 3CX phone while kept on hold...

I need to configure anything special ?

Hi iptsupport,

 the 3rd Party Phone must support the Cisco-proprietary feature signaling for MoH to work (check this link as a reference).

Hope this helps.

Hi Marcelo Almeida

Thank your for your quick replay . 

I will try to follow the configuration in the link . 

[iptsupport]

Do you have example to a client that support MOH  ? 

[Marcelo Morais]

Hi iptsupport,

 sorry I don't have an example of a third-party Phone that support MoH.

 I think (I'm guessing right now) that Polycom equipment has a better chance to support MoH, because the Cisco 7936 and 7937 are both Polycom/Cisco equipment.

Hope this helps.

Hi,

I couldn't found better piece of information which list all cases how MoH is implemented for various terminals and hence thought of testing the same. My observations;

SCCP phone -> Hold -> SIP Phone -> MoH plays to SIP phone

SIP Phone -> Hold -> SCCP phone - > Doesn't play MoH

SIP Phone -> Hold -> SIP phone -> Doesn't play MoH

Please note that I have checked with both Xlite and 3CX, results are same.

I have verified in wireshark also,  call manager is not sending RTP packets to held party when call is hold by third party SIP phone.

Checked in CUCM 9.1

Thanks

Vivek
