My existing system is being used with Cisco CME 8.6, Cisco MCS 7825-H3, DTM, IPAS
and the IP phone model is CP-7821-K9 and Cisco Unified IP Phone 7942G . In that system now audio conference is not being used. As per CME, it supports 3 way conference. Is it possible to make more than 3 ad hoc conference calls in that system? If possible, then how? Is there any modification required in that existing system to make multiple calls? Need your kind help. Thanks.
