[SR-Users] Remove/Append headers in 200 canceling and 200 ok to BYE

Thu Jan 12 19:04:43 CET 2017

Hi Daniel!

Thanks for your answer.  The idea is to show only a few headers. In BYE
works great. I'm removing and adding the following hdrs:

*User-Agent: Kamailio. <---I will try what you said*
*Supported:.*
*Allow: INVITE, OPTIONS, BYE, CANCEL, ACK, NOTIFY, INFO.*
*Accept: application/sdp, application/gtd.*

For example in following messages ( Kamailio is 172.16.213.38)
