Hi,


This normally happens when there is a CODEC mis match between the 2 end points. When you said 3rd party, is that the PSTN Number you are trying? or any Number where you need a xcoder to play a role?



Please rate if that helps.


Mohsin.

By the 3rd party i mean the 3rd DN.


This is the scenario of what happens. whenever a call is initiate form A to B, then conferencing C drops the call with B and establish the call with C and a message is diplayed on A " cannot complete conference"

Hi.

First verify that conference bridge is correctly registered on cucm and that is associated with Media Resource Group an Media Resource Group List.


If Phones are in different location, verify that the location allows enough bandwidth to establish a call conference.



Let me know

Location is only for BW between sites...it doesn't determine CODEC.  Take a look at the Region configurations.  If the SW conference bridge is in a different region than the phones and you are using defaults, the intra-region codec default is G.729.  However, SW resources only support G.711.  You will need to ensure that the region assigned to the phone specifies G.711 for calls between that region and region(s) where SW media resources are deployed.
