Hi all, I'm planning on connecting our Asterisk to our legacy PBX (an Avaya INDeX). I was originally going to sit it between our ISDN connection and the INDeX (tried it, worked ok) but now I intend to hang it off a spare PRI card just so should the * fail we keep our ISDN's at the INDeX, yes I've looked at ISDNguard but little info from the manufacturers. Anyhow, I'm now thinking about using QSIG, I've configured two spans of a TE405P as switchtype = qsig and connected them back to back for testing and calls are ok. However, I cant find any documentation relating to what messages I might see come across the link once I connect it to the INDeX and what I can do with them when they do. Any pointers anyone? Thanks Steve

Q.Sig can be a bit complex as is a 'private network' made of E1 connections and as such also contains some SS7 alike funtionality, but Layer 3 wich is of interest for you is not that different from Q.931 (which is the base for EuroISDN and NI3).
