This really sounds like a Codec issue. Have a look;
Cisco CallManager Software Conference Bridge supports only G.711 a-law and G.711 u-law and does not understand any other codec such as G.729. External callers cannot be added to the conference if they use a codec other than G.711. In order for calls that originate as G.729 to be connected with phones that use G.711, you need to use a transcoder.
