Re: [OpenSER-Users] remove_hf from textops does not remove whole header field

Hi Bogdan I do not call force_rport specificly from the script. But I checked my eyeBeam and he uses rport, so it is invoking it internally I guess. I switched it off now. But the send() function was indeed what I was looking for. I use it for testing a SBC, I need to know whether it will reject it or not. Thank you for your help, that was all I needed to know.

The bogus result is because of how openser internally process the changes on the message. The changes are not immediately applied, but separately store (as lumps) and applied at the end. What happens in your case, is like this: 1) probably you use force_rport() function that adds the rport param to the top most VIA hdr (as add lump) 2) you call remove_hf() that creates another lump to delete the top most VIA 3) when lumps are applied, the original VIA text is removed, but the rport text is printed because of the add lump (step 1). Probably avoiding the force_rport() function will solve this issue, but note that this function is also internally called. Regarding the addition of the local VIA (when forwarding the request) - this is mandatory by RFC3261 - a SIP proxy must add its VIA. But if you really know what you want to do, try to use the send() function - this will simply send the request to another destination without adding the local VIA.
