One of our trunk provider is IP based and it is actually extracting our IP from the FROM header when sending a REGISTER request. Somehow, we are unable to modify it. As you can see on a REGISTER message the IP found in the FROM is 88.151.130.61. We want to change that IP to the one found in Contact or VIA. We also try to add it in to the FROM domain in the trunk configuration but it doesn’t seem to change it. Even after a SAVE & APPLY. Please be advised that we delete the last set of digits of our IP address server for security purpose.
