SIP contact header during SIP Registration

SIP contact header during SIP Registration Empty SIP contact header during SIP Registration

Post by starunj Mon Oct 04, 2021 10:21 pm

Hello Everyone,

Wanted to request if anyone has any ideas on how to overcome this problem we are facing.

Our provider is forcing us to use a "contact header" like user (at) freesbc_ip_address during SIP registration.

However, from FreeSBC, the contact header is going as interfacename (at) freesbc_ip_address.

Specifically, in our case, it is sending voip1 (at) 10.0.67.134, but should be 68249999 (at) 10.0.67.134.

On FreeSBC, the interface name cannot be an integer, so, we can't even rename voip1 to 68249999.

I'm attaching the image we received from our SIP trunk provider as well as what we are seeing from our side.

Any help or ideas on overcoming this will be greatly appreciated. Thank you very much.

Hi

There is no way to manipulate the Contact header in Register messages at the moment.

Thanks.

Thank you very much for your reply. I had a couple of questions:

1. Would this be a possibility sometime in the future?

2. Would it be possible to allow us, through FreeSBC, to set the interface name to an integer? Because, presently, the contact header is being sent as interface_name (at) ip_address (voip1 (at) 10.0.67.134).

We are keen to get this to work with our SIP trunk provider.

Hi

We already have tracking for manipulation of the Register messages. But I cannot give you a date yet.

You cannot enter an integer value for the interface name.
