[Spce-user] SIP 302 Redirect to different IP

Good evening,

User has a SIP Redirect Server and wants to “redirect” incoming calls to one of his many other servers.

The DID used in this example is 123456789.
The Redirect Server has IP

The Contact to reach the SIP Redirect Server is sip:123456789 at

The Redirection goes to sip:123456789 at (only the IP changes).

I have activated “allow_out_foreign_domain”, so the LB accepts the SIP Message.

But the PROXY tries to redirect the call to the very first contact (e.g. IP and not the contact provided via the SIP 302 Message.

Is it possible to have the PROXY use the full contact during a redirect?
