I was trying to setup instant messaging in asterisk server. For the client i'm using Blink Softphone. I did add to my sip.conf
[general]
accept_outofcall_message=yes
outofcall_message_context=dialplan_name
auth_message_requests=yes
and to my extensions.conf
[dialplan_name]
exten => _XXX,1,MessageSend(sip:${EXTEN},"${CALLERID(name)}"${MESSAGE(from)})
So this is a simple extension for testing. But when i try and send the message from user1 to user2 i get in the asterisk log:
[Jan 30 21:17:47] WARNING[6420][C-00000005]: chan_sip.c:10515 process_sdp: Insufficient information in SDP (c=)...
What can be wrong here? I'am sure that the clients are on the nat, so i do have both nat=force_rport,comedia for all my users in sip.conf
My asterisk version is 13 (latest).
[UPDATED] I turned on the sip debug log, and tried to send the message (first i get some weird retransmission):

arheops was right! Using INVITE request as basis request <- here it is. Instead of MESSAGE for some reason INVITE request is used.
