Does the same issue happen even if you specify the SIP Server's IP address instead of the domain name in the SIP UA's setting?
If you use the domain name in the SIP UA's setting, the SIP UA will send a REGISTER to the SIP Server through a router because the domain name points the router's global IP address.
Some router products can not handle this kind of routing. |

The issue does not occur when IP address is mentioned.
As mentioned, this is a localised lab setup and there are no routers in between. Moreover the Reigster packets are reaching the SIP server, the issue is that the SIP Server is responding with 403 forbidden when the Register messages have domain name. |

If REGISTER's request-URI indicates a domain name, the SIP Server tires to resolve its IP address with the DNS, and forwards the REGISTER to the resolved IP address.
You said that the domain name points a global IP address.
Therefore SIP server tires to forwards the REGISTER to the global IP address.
To prevent it, put the domain name at the [Interface address x] in the [Configuration]->[System] page. |

Have tried with the domain name added as an interface at Configuration -->System page. But still getting 403 from SIP server.
Note: The same setup was working earlier. |

Rakesh,
Are you using Auth for REGISTER?
Let you disable it for testing.
It is the "REGISTER=on/off" in the [Configuration]->[SIP] page.
You need to restart the SIP Server after you changed the setting.
Also make sure that the SIP server's PC can reach the DNS server.
Try nslookup for the domain name.
If nslookup can not resolve the domain, you need to set DNS settings correctly. |
