To follow up on my own reply. I just tried this with one of my standard peers that I use for a softphone on a 1.6.2.10 and see the registration attempt come in at the console and a warning comes up : Host '192.0.2.40' disallowed by contact ACL (violating IP 192.0.2.40) : Registration denied because of contact ACL The peer does show in sip show peers and the softphone (twinkle) shows a Registration Fails with a 603 denied. So I'd say it's working -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
