[asterisk-users] Treating T1 as trunk in/out, not individual lines
I'm tying a Nortel option 61 to asterisk via T1. I don't want to split each of the t1 channels out into individual lines (tied to a specific extension) - so a trunk in and out. Assuming PRI over T1 signaling, how would I pass the CALLED and CALLER info across the channels so each side knows what to do? Is there something in the PRI protocol you can point me to for figuring this out? Thanks, MD -------------- next part -------------- An HTML attachment was scrubbed...

A PRI is a primary rate ISDN. B channels carry voice, D channel handles the information & signalling in ISDN. Lyle -------------- next part -------------- An HTML attachment was scrubbed...
