Hi All,
I integrated with third party voice conference solution called Astrisk.it is integrated with CUCM 6.1 through SIP trunk.
When I reach 50 participants per conference I can't add more ip phones to the conference;i get fast busy tone.
Is there any limitations on CUCM SIP trunk to 50 participants only.
Note :
When I join the conference from mobile phone,it works fine;problem happens only when joining the conference from ip phones .
My ip phones are all SCCP phones.
