Hi,

I am using Kamailio (4.0.3 (x86_64/linux)) against an MSS in the mobile core network.

Kamailio receives an INVITE with following bodies:

Content-Type: application/sdp

....

Content-Type: application/ISUP;base=itu-t92+;version=itu-t92+.

....

How can the latter part i.e. the ISUP body be removed so that I just keep the sdp and relay.

I have gone through the docs for textops, mangler, sdpops. What other functions are there for sdp removal apart from sdp_remove_line_by_prefix.

It's a bit impressive that Kamailio could at least respond to all such multi-body (SDP+ISUP) INVITE messages while asterisk 1.8 (the one in debian apt) could not.

Best regards,

Adnan
