I have recently been contacted by people with Asterisk installations that hang up calls after 10 minutes or so with regards to E1 connections. I have had a poke through their setups, and it all looks standard. I have even tried the patch from this site http://forums.digium.com/viewtopic.php?p=15702&sid=5fd90c0526e702f1d0b83ecc08fcfc51 on one of the installations but it didn't help. Can anyone think of anything else to try? I can only think that the Telco has something set up slightly wrong at the PRI_NET end of things. ;) later, Paul Hales -- Paul Hales Technical Manager AsteriskIT www.asteriskit.com.au bus: 03 8320 8100 mob: 0434 225 491
