[Kamailio-Users] function to send ACK message

[Alex R.S.M]

Hi,

I need kamailio proxy to reply with an ACK to 200 OK, i.e. the proxy stays in the call:

UAC  sends INVITE to kamailio, kamailio forward it to UAS
UAS  sends 180 to kamailio, kamailio forward it to UAC
UAS  sends 200 to kamailio, kamailio forward it to UAC AND sends ACK to UAS


I was wondering what function I can use so kamailio can generate an ACK message to response to 200 OK.
Apparently both t_reply () and sl_send_reply() functions create responses and not an ACK message.

Thanks,
Alex
