I have an AASTRA 57i CT that has been restored to defaults that I am trying to get to work with my PBXNSIP with no luck.
The only modifications I have done thus far is under the SIP Settings> Proxy IP/Port > Proxy Server, I put the address of the PBXNSIP.
Can anyone tell me what else needs to take place or happen to make this phone register to an extension?
This is an in-house demo so security is no factor here. I am looking for the easiest route in making this phone make and receive calls to other extensions.
