Hi all, I was wondering if OpenSIPS can help me with scenario explained
below;
I have a Fax Server SIP and T38 based. It use a SIP based Pbx as PSTN
Gateway, so requested external fax number are sent from Fax server toward
PBX and then forwarded to Pstn.
Here there's a full SIP trace:

So, what I would like that OpenSIPS do for me is analyze "FROM" header into
first INVITE message than query a DB and if query matches then modify the
"TO:" header.
Example:
From: Fax Alcatel <sip:+390522375507 at 172.16.52.7:5061>;tag=B0A3C63723A2
Here OPENSIPS should analyze "+390522375507" then if query is ok modify
To: sip:00522375568 at 10.9.6.3:5060
into
To: sip:870190522375568 at 10.9.6.3:5060
Is this possible????
Naturally I will put OpenSIPS in the middle between Fax server and PBX and
fax server, as SIP PEER, will points to OpenSIPS ( OpenSIPS then will be in
charge of forward everything to PBX ).
What do you think???
Thanks a lot for your replies.
