[AASTRA 57i CT with PBXNSIP]

Actually, plug and play should work. Punch in the IP address into the "TFTP server" setting into the phone, and set the Admin->Settings->Ports->TFTP policy to always send the password and set at least one extensions MAC address to "*" and give it a try.

 

Otherwise, just make sure that you fill in the outbound proxy on the phone and also use a domain name in the line settings.

 

Got it, thanks for your prompt help.

[AASTRA 57i CT with PBXNSIP]

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.
