I have an asterisk PABX exuipped with Digium TE210P.
There are two trunks connected to different Telcos (both E1 ccs,hdb3,crc4).
We are facing contant problems with one span, while the other is always operational. Customer blames asterisk side, while we think it might be a problem on Telco’s. Restarting asterisk restores service on span 1, we think it simply sends Group Reset to the switch, which unblocks all channels.
How to check on which side the problem is? How to troubleshoot the situation?? During this kind of failure, we show the customer, that other span is working fine (we place test calls to prove it). Later on we restart asterisk (is there any possibility to restart just one span without restarting asterisk?) and system is fully operational till the next failure.
We desparately need support
