Thanks Norm,

That is exactly what I am looking for. It solved my problem. I used the prefix to identify calls that should be routed to a particular carrier by Openser. But this added prefix affects the interop with some applications with the carrier, hence the need to strip off the tags i added.

Rgds,

Tolu

Perhaps the "uac_replace_from()" function is what you are looking for.

Note that modifying the "From:" header is NOT allowed by the standards.  Please review the mailing lists in regard to this topic as it's been discussed many times.

OpenSER gives you enough control to "shoot yourself in the foot".  It it possible to create a configuration that can solve your "internal business situation" but might cause interoperability problems with others.

Regards,
Norm
