[sr-dev] scscf modifying contact:

[Daniel Ciprus]

Hi,

For our application to work we'd like to see not modified Contact: from Kamailio being sent towards our AS. Unfortunately this is not happening now. Below are REGISTER messages from client and message which is sent to AS. I wasn't able to find any logic in .cfg file so I thought this would be the place where I should post my problem. According to 3GPP TS 24.229, RFC 3261, RFC 5626 it seems like this is not the behavior which should be happening.

Thanks for any hints on this topic .

Dan
