I'm looking at this: http://www.3cx.com/blog/support/documentation/networking/sip-proxy-manager and it looks fairly easy. Does anyone know if I can configure a Polycom SP IP430 or IP550 to connect remotely?
If you are planning on setting up several "remote" phones at one location, then the Proxy Manager is probably the best way to go, it can eliminate a lot of headaches.
If it's just one set, and the set has a STUN setting, then there should be no issues. Of course, problem can arise due to many factors that may be unique to your particular installation, including the type/make/model of router that the set is behind and other devices on that network.
Proxy manager is the best solution in case if multiple phones are connecting to PBX from the remote office.
P.S. If you don't like Proxy manager then, for fun, you can try to configure your phone to use STUN server on PBX_IPBX_PORT...
It will be interesting experience...
ok, i see, so i can install the proxy manager on a pc, have even an unsupported phone like the IP 430 point to that...soI should still be able to do auto provisioning then?
