I have Call Manager Business edition and H323 Voice
Gateway 2821 Router. I have configured the E1 controller for incoming and outgoing calls
but I am having a problem with the outgoing calls where incoming calls are working fine without any issues.
The error that i am getting when i do a DEBUG ISDN Q931 is the following:
Cause i = 0x82A2 - No circuit/channel available
any help will be highly appreciated.
Seems like E1-controller circuits / channels are not properly connected or configured.
Router# Show controller E1
# Show Interface Serial 0/0
This CLI gives the E1 Status and the Alarm details
Check the E1 status. If E1 is down, rectify the E1 alarm by checking the Physical connectivity
Ensure the transmission losses, slips, frame loss, Line Err secs etc on the E1 are Zero.
Data in Interval 6:
0 Line Code Violations, 0 Path Code Violations
0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins
0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
Follow the Action Points till the Controller E1 Status is UP
and Zero losses on the link.
Typical Physical Layer Issues are
Physical E1 Disconnection
Framing should be No-CRC4 at both the End. Encoding should be HDB3 at both the ends.
If you need E1 controller configuration details, will give you the details..
Whether your problem is solved ? If not give me the Debug Voip ccapi inout output..
