Does it possible increase cSeq manually (for example remove and then append headers?) for UAC module when send INVITE messages with Auth, or kamailio have pseudovar for this header?

Yes, you can. But this will break subsequent CSeq numbers in all requests within the dialog. Also, you will need to restore proper CSeq for replies to the INVITE for which the CSeq was altered. -ovidiu On Oct 30, 2014 9:59 AM, "Yuriy Gorlichenko" <ovoshlook(a)gmail.com> wrote:

As I understand UAC module can not be used at production as module foroutgoing calls from kamailio to provider with this limitations? 2014-10-30 18:24 GMT+04:00 Pavel Eremin <eremina.net(a)gmail.com>om>:

This feature (increasing/decreasing cseq for calls authenticated to the next hop by kamailio) is available with 4.2.0, by using dialog and uac modules. See more details at: - http://by-miconda.blogspot.de/2014/10/kamailio-42-tips-7-increment-cseq-for… Let me know if works ok for you, as I did not test it yet extensively.

This feature (increasing/decreasing cseq for calls authenticated to the next hop by kamailio) is available with 4.2.0, by using dialog and uac modules.
