Hello Ali,

Have a look at this function:

Be sure to properly read about how it works and the formal implications of using it, though.

Hi,

I’m using LCR module in Kamailio , where matching of the rule (From-URI in LCR-rule table) is currently based on user part of sip address in From field (highlighted below in blue).

While we need to change the identification to be on the otg value sent in the sip address in From field (highlighted below in yellow).
