I am looking for assistance or pointed in the right direction of setting up conference calling in CUCM 6.1, with 2811 running in SRST mode.
I have a remote site registering to 6.1, with a local ISR running in SRST mode. I do not want to set up a media resource unless I need to.
Here is what is happening.
I call outside line to remote location.
Call is answered.
Called party presses Confr softkey, places call.
New Called party answers, confrn softkey pressed again, call is dropped and I hear fastbusy, however the call between the two stays up.
It sounds like a Codec issue but not sure what to look at.
