confused with your last paragraph when you say "the circuit >>does establish and
pass calls but resets frequently due to slips". Are >>those calls to/from
asterisk talking to the Nortel? Yes that is correct. The
Nortel switch connects to the PSTN but not the Asterisk. It connects to the
Nortel. While the circuit is up I can call extensions on the Nortel from the Asterisk
and visa versa. >>Or, are you routing >>incoming pstn calls
from the central office through asterisk to the Nortel? No >>Also, have you tried
any of the "pri show ..." commands in asterisk, or >>any of the pri debug
items? Yes. When the circuit is up I can pri show span 1 and it
show partitioned up and active. Ronnie Jones Engineer - ICT Clay Electric Cooperative, Inc 352-473-8000 ext. 8272 352-473-1929(F) 352-745-0910(C) |
