Hello I'm sorry if this is a recurring subject, but I'm having problems registering my SIP configured 7970 phone with my Asterisk server.

The phone is using SIP 70.9-2-1S firmware, and my SEPmac.conf.xml file looks like this:

I've tried multiple config files but this is the only one that seems to be able to send the REGISTER request to the server (the others simply hung up displaying registering).

 

By debuging the Asterisk server (located at 192.168.1.201) with "asterisk -rvvvvvvvvvvvvvvvvvvv" and "sip set debug ip 192.168.1.139" (correspondig this to the phones IP) I get the following:

And then it just keeps trying to register.

 

The phone's status log doesn't show anything, it just hangs displaying "registering".

 

I'm not really sure, but by looking at the Asterisk's debug output I think its trying to register using a different port than the 5060 and also doesn't send the Authorization parameters in the header. I'm saying this after looking at the debug output of a 7960 phone that does connect to the server succesfully leaving this output:

I managed to track the error down. As you pointed out, the problem solved by disabling the nat configuration in the Asterisk configuration file.

Thanks for all the help.

<natEnabled>true</natEnabled>

Change that to "false" and try again.

Did you factory-default the phone (so the phone can download the changed config)?

Yes, the phones came with the SCCP firmware. I've upgraded and tried this configuration on two of those phones with this results.

Try the option above. 

Next, after the phone has rebooted.  Look at the status message of the phone.  What does it say?

By changing the transportLayerProtocol to 1 no registration log is captured by the Asterisk server.

Also the status message screen shows the following:

2nd line (from the top) means the config was downloaded by the phone and was "accepted" with no issues.
Last line states the dialplan is missing.

Yes I know that I'm not providing any dialplan configuration, but from what I recall from other cisco phone models that shouldn't interfere with the phone line registration.

Is NAT and ALG enabled on the network?
NOTE:  I've had 7970 registered to Asterisk but I've never used 9.2 as a firmware.  I used whatever latest firmware that was available.

NAT is enabled but I'm not really sure about the ALG. The phones' network SIP gateway is different from the internet one (this one beeing the main router), where should I look for this configuration?

I don't see a SIP ALG option in neather of them, but I could replace one if needed. My main router is a "Linksys WRT54G2", while the one that functions only as SIP gateway is a "Nisuta NS-WIR150N".

Talk to the provider if they support NAT &/or ALG. I suspect they don't so these two functions need to be disabled on the router as well as on the Asterisk, Extension settings.

The NAT function is supported and needed for the phones to work (the 7960 models only work with NAT enabled).

In the case of the ALG as I understand (and please correct me if I'm wrong) messes up the connection with the public network. In my case the problem is within the internal private network. The phones don't get to register with the internal Asterisk server as it is seen in the Asterisk's debug output.

I'd bet it has something to do with the phone's network configuration. Or does the registration request in the 7970 models always looks like this, totally different from the 7960's one?

7940/7960 phones are easy to integrate with Asterisk because the last known working firmware version is very stable.
The firmware for the 7970 is, however, not. I know of two version that is and 9.2 is not one of them.

Attached is known working SEPmacaddress.cnf.xml config from a working 7970. 

Take note the config is based on 9.4(2) firmware.
