Hello,

Why in SEMS, some changes (in transparent SBC profile) in sip headers do not apply. For example i want to change CSeq or Contact header like this:

# transparent SBC profile
# defaults: transparent
RURI=$r
From=$f
To=$t
Call-ID=$ci_leg2
CSeq=$H(CSeq)
Contact=$H(Contact)

When I run SEMS, CSeq and Contact do not change, while other headers change.

 [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:434] INFO:  SBC:      force outbound proxy: yes

 This issue caused the Asterisk could not pass the Authentication process in "match_req_to_dialog" function because the CSeq is the same as the dialogs. So the Asterisk thought this message was a LOOP message.

Has anybody encountered this issue in SEMS? How did you solve this? I know there are some ways for doing this with Kamailio, But i focused on issues in SEMS
