Also explain the firewall type and what it is being used for. Typically you DO NOT WANT it to be sip aware unless it is a full SBC, which means making sure nat is symmetric and the sip alg/proxy is off.

The sipx server is in dmz network. I would like to connect a phone to sipx server from internal network. I am able to initiate phone calls from internal network to phones in dmz and there is sound both ways. However, I am not able to initiate calls from dmz phones to internal network. Looking at registration info, I see that internal network phone ip is that of external interface of internal firewall. The firewall is sip aware. I am not sure if the problem lies in sipx server is not able to contact internal phone or my firewall configuration is incorrect. I am assuming that since I can connect from behind a firewall over a wan to a sipx server which is behind a firewall, I should be able to do this, as well. Any help is appreciated. Thanks in advance. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/ _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
