Cisco 7970 IP Phone with 3CX Server

[DexDeadly]

Hello,

I am trying to get help in setting up my newly purchased Cisco phone to work with my 3CX server. I have found a thread on here that someone named GordonKapesMZ4 has mentioned he has had this working. I seem to not have a properly configured xml file to make it connect to the server. If someone could help me out that would be really great. I am trying to set the phone up to use in a business I'm trying to get going. If someone could please help me out with this I would appreciate it greatly!

Hi Dex,

Here is where I found the information on how to get the phone working,

http://www.voip-info.org/wiki/view/Asterisk+phone+cisco+7970+SIP

I assume the following procedure would work on 3CX.

Let me know if any of that helps?

Hello,

I've used this document and it seems I last night was able to get it to check viocemails for the extension I programmed and it seems I can make outgoing calls. However it doesn't connect to the line and register. So I can't receive the incoming calls. The line comes up with a red x on the phone.

Do you have NAT turned on when the phone registers?

I know I had to toggle the NAT on and off when trying to register to the UCx platform. Finally the phone connected when I turned NAT off.

Toggle NAT on in the phone in the XML config file?

 

[GordonKapesMZ4]

ON the 3CX itself. I assume there is a setting on 3CX that allows you to choose NAT on or off? I haven't worked with 3CX so I don't know for sure.

That is, choose your extension and SIP parameters on 3CX and see if there is a setting that allows you to turn NAT on or off for that particular phone. I know on the Asterisk configuration file, there is a setting that says NAT=yes or no.

I guess i misread your post from a few years ago. I do not see anywhere to turn off the NAT in 3CX.

NAT/ALG check:L:4.2[Line:10000>>12158331298] RESPONSE 200 on 'INVITE' - some of SIP/SDP headers contain inconsistent information or modified by intermediate hop
SIP proxy detected:
Record-Route:<sip:209.216.2.212;lr;ftag=a904dc37>
Media session IP ('c=' attribute) is not equal to the SIP packet source(IPort):
Media session IP: 209.216.2.203
Received from: 108.36.212.53

I get this in my log when calling out actually. I'm putting the server in a DMZ zone see if I can eliminate it.

Sorry that I am not that experienced with 3CX. I would recommend you call Alpha Telecom in Toronto and ask for Andrew Daly. They use a 3CX in their office.

Does 3CX support skinny out of the box?

hairless, those tutorials wont work since the 7970 requires and XML config and not a regular configu like they use.

Some time ago, I had the same problem when I tried to use the free SIP firmware version 9.3 for a 7941 phone that I bought with SCCP firmware. The phone would come up, but it would not send any registration request to the switch (and consequently would not register). As registration is required to receive incoming calls, no calls were sent to the phone.

I wasted quite some time trying to figure out the problem. I eventually gave up and tried an older firmware (8.4.1 to be specific). With the older firmware, the phone came up, registered and everything worked as it should. Maybe it's something in the XML configuration file that must be added to instruct the 9.3 firmware to register...

If you are using 9.3 firmware (or another 9.x version), you could try a downgrade to an 8.x firmware version.

Currently I have SIP version 8-3-1
I have the ability to make calls and I can call extensions I just can not receive calls. I do not even see in the log the phone trying to register. I do believe my config is missing something and I keep trying everything I read. Still nothing makes the phone try to register to receive the calls. i've tried both of these XML config files.
