Conference between IP phone Cisco

Hi Voice Team,

I have a environment with SIP phones and Cisco "SCCP" phones registered in a CUCM 8.5.

But, the conference is working just for sip phones...

The conference bridge configuration was attached...

What is the problem? 

thanks.

You do not need DSPFARM if your desire it to use CUCM as the conference bridge, however if you have enough PVDMs on the GW it is always recommended to use hardware conference bridge. 

As to Truster Relay Point it is set on your conference bridge, see the last field on your screen shot.

Are all the phones in the same Location and Device Pool or are the SCCP phones in different DP and hence trying to negotiate different codec? Keep in mind software conference bridge can only do G711 codec.

Do you require Truster Relay Point as you have it set? Have you tried removing it?

HTH,

Chris
