[SR-Users] Help find out where to modify request uri

[Simone Felici]

Hi to all,

I need to edit our ser installation (OLD ser-2.0.0-rc1) implementing a check to rewrite the INVITE 
URI address in case a flag on a DB is set or not. I'm not proof on this and as always the solution 
is to find out on the production system without the possibility (for now) to upgrade to most recent 
version. In fact I would load the flag with the db_ops module.
The scenario should be the follow:
1. a call is coming from sip or from pstn to an internal sip account
2. the ser should check if a given flag for the called account is set (db_ops)
3. if it's set it should take the destination URI (taken from location db table) and rewrite the 
number to another known number. i.e. from sip:123456789 at IP;uniqu=... to sip:new987654321 at IP;uniq=...
My first issue is to identify WHERE ser execute the INVITE to the sip account and how rewrite the URI.

Could someone point me to the right place and give me some suggestion?

The ser.cfg used could be read from a previous post of me:

Thank's a lot!
