i have a CCM 5.3, conect to a AS 5300, dial peer are made in both device to call siemens phones. The AS 5300 is connected to Siemens Central via E1,
when i call to siemens ext the call got a delay to set the call,
I verifiqued the dial-plan and its OK, and the E1 Channel.
What would be the cause of this problem?
