CME - Conference does not works

[dsobrinho]

Hi everybody,

I have configured a CME for a small office, and during the tests the conference did not work. I have re-check the configuration and cannot find the problem. I have attached the configuration of CME here. 

Does anybody knows if can be a bug of IOS for this router 2801 or a mistake in the configuration ?

GW uptime is 2 minutes

Daniel,

Your config indeed looks correct, are the profiles registered with your CME? Can you post "show dspfarm all"?

Hi Chris,

All 2 profiles (XCODEC and CONFER) are registered, however, I will return this Friday to the customer and  I can collect more information.

I have check "show voice dsp error" and there is no error.

My question was not about phone registration, but DSPFarm registration. Since you are using hardware conferencing the defined profiles register with CUCM/CME via SCCP.
