Hello,
I am setting up a Cisco CME 10.5 as a conference bridge for SIP Phones.
The CME is already serving SCCP phones and the DSPs have been configured to provide hardware resources for conference calls and transcoding.
I am now configuring the SIP terminals to use the CME as a Conference Bridge but I am getting an error 403 : FORBIDDEN When establishing the Conference Call through the bridge.
I have tried using the number I have configured for SCCP ad-hoc conference (A020) in the form of SIP URI: A020@<IP Address of CME> but I get an error 403 Forbidden when setting up the conference from the SIP Phone.
A020 is the number I gave to the DNs that I configured for the AD-HOC conference.
Any ideas?
Many thanks,
Francesco
