Ad-Hoc conferense is not working properly

Hello!

Conference at the CCM 4.2 starts on the phones after 3-5 minutes. RTP stream appears immediately, but voice on the phones is heard after 3-5 minutes.

Please, help!

Hi there,

the software conference bridge doesn't support g.729, so that might be part of your problem, try a conference with just g.711

also, do you have a security device, eg firewall between your phones and the CUCM server?

regards,

Paul
