I have a asterix PBX running my system and I upgraded my security with a cisco ASA 5505. Now all the extensions are working including the remote once. Everything elase like internet... other servers all working fine. Only problem is that when ever someone dials a landline number from an extension it does not go through.... seems like the firewall is blocking it but I cannot figure out why or how. All the NAT and Access list is fine. Although I have no idea how to accept the SIP PROXY IP through the firewall and I am guessing that might be the problem. There is no any other problem and I am 100% satisfied with the ASA5505 except this problem... Any help is appreciated..
