Hi, I've got two pa1688 phones that I want to set up to communicate between branch offices without a gatekeeper. Both phones will be behind a firewall and I want to use port forwarding so the phones can communicate. I tested the phones behind a firewall on the same network segment and there were no problems at all using sip. However, I then moved the phones into situ and port forwarded udp on 5060 and 10000 - 20000 at both branch offices firewalls. I set the rcp port to 10000 and the sip port to 5060. The phones were able to ring each other, however, there was no sound on both ends. Can some one please tell me which ports I have to open in order to make communications between the two branch offices using these phones. Or share a config or suggest another protocol so I can make this happen. Thanks, Oliver
