Problem with E1 PRI

jliberm · May 31st, 2006, 03:39 AM

Hello,
I try to connect Avaya IP Office PBX to Nortel TX1 (Rel.18) by E1 Pri.
The only option that I can define the E1 Pri - ETSI, "USER" side on the IP Office PBX. TX1 must work with E1 Pri - ETSI, "Network" side.
The problem is: when I call from TX1 to IP Office, the telephone is ringing, but when I try to answer the is disconnected, as I see in the trace (from IP Office side), TX1 is not sending "ConnectAck".
The card that I am using in TX1 PBX is "IDDP TLTT05AA", Rel.07.
Does anybody have any ideas?
