Hi, we have CME 4.3 on 2811 router. When we try to make a conference call, we got a message on the phone screen says " can not create conference".

After that, we still have the first call on hold and the second call resumed.

Any suggestion?

Sounds to me like there is no conferencing resources on the router, or the dsp's have not been configured to be! can you please send me you configuration!

should that use soft decoder to transfer between G.711ulaw and G.729r8? We are only use 3 way ad-hoc conference.

Anyway, I config the dsp resource, it shows conference connected, but there is no sound from 3 callers.

Is there anything wrong when I config the dsp? How to trouble shoot such kind of problem?

Thanks again.
