Re: Register Cisco 7821 to voip.ms using SIP

You need the SEPmacaddress.cnf.xml and the dial plan. That is mandatory.
So why is the phone not downloading those files?
Did you actually factory-defaulted the phone or not?

No, as I said, the phone is indeed downloading those files. It is just not
doing working. It gives no status messages indicating an error in the
config, and still does not register.

Disable NAT.
Disable ALG.

Is the phone username/password correct?

Do you mean to disable nat and alg in the phone settings, router, or pbx?

Yes the username and password are correct.

Everywhere.

I don't see how I can disable NAT in my router and still have a functional network though. I also can't find NAT or ALG settings in the phone configuration. However I did disable both in the PBX with no luck.
