SIP Invite "FROM"


#1

Good Afternoon,

So we have a client who has configured UCM6302 everything is working.

We are having issues with outbound calls, 403 Forbidden.

The SIP provider is saying that the issue is that the From should have the SIP server’s address, not of the clients.

Did you ever encounter this?
Example:

From: <sip:356123456@Clients Public IP>;tag=c64d7688-e5ce-4f66-b94f-34a5a5949879

The SIP Provider is saying is should be

From: <sip:356123456@PROVIDER SIP ADDESS>;tag=c64d7688-e5ce-4f66-b94f-34a5a5949879

Is their a way I can change the address in the “From”"

Thanks

From Domain: PROVIDER SIP ADDESS

But if you have external public it can be SIP ALG turned on router.
