[Asterisk-Users] Problem with NAT on Asterisk 1.0.1
Hello: We have a strange problem with Asterisk 1.0.1 We made a succesfully installation of Asterisk over RedHat. We have a FXO card installed and configured, and works great. The Asterisk have a public IP address and the users are behind a firewall and use invalid IP addresses We made some test with X-lite, and a couple of IP-Phones (GoldenNet EMT-22 and ET-22). The X-lite users can made and receive calls between each others but IP-Phones didn?t receive calls, but can made callings to xlite users or to the other IP-phone. All the users are registered in Asterisk, and was configure as this extract of sip.conf: [1234] type=friend context=local username=1234 secret=1234 host=dynamic qualify=1000 nat=yes mailbox=1234 We installed Debian to probe another Linux distro, we use the same machine with the same hardware and configuration files, and the IP-phone can made and receive calls without problems. Even all the users can made callings using the FXO card (Zap channel). Only for test purposes we installed the IP-phones on the external side (with valid IP's) and...... the IP-phones work great. Did anybody have an idea about what is the problem with the configuration files in the asterisk? We are clear about NAT is the origin of the problem, but we don?t know why worked with Debian and not with RedHat. Any advice or suggestion will be very useful. Cheers, Octavio Vargas
This is not an Asterisk Problem. It is a SIP problem and most likely related to the different firewalls the SIP phones are located behind. You will need to configure the firewalls, use real addresses for the SIP phones, or use IAX clients for phones behind firewalls.
