My current system confiiguration is:
Asterisk 1.2.4 on a Dell PowerEdge 2850 w/ a Digium TE411P card
We use 2 T1 PRI lines (one for local calls, one for LD calls)
The problem I am experiencing is that every time I use the ‘reload’ command we are unable to make calls out our local T1 line - ZAP/g1 (span 1 on the card ). Long distance calls made on ZAP/g2 (span 3 on the card) work without any problems.
Restarting Asterisk resolves the problem everytime. Obviously, that’s not a very viable option as we constently have calls in progress.
Below is the console output:
– Executing GotoIf(“SIP/183-db43”, “1?s|3:s-NOSTRIP|1”) in new stack
– Goto (macro-tl-dialout,s,3)
– Executing Set(“SIP/183-db43”, “CALLERID(number)=206XXXXXXX”) in new stack – Executing Dial(“SIP/183-db43”, “ZAP/g1/4415555”) in new stack

‘Show channels’ will show the current number of active calls - typically 6-12 calls.
Has anyone seen a behavior like this? Any suggestions?
