Asterisk Instant Messaging

Asterisk Asterisk Support

Hello. I’am trying to setup the instant messsaging in asterisk 13. I did add to my sip.conf

sip.conf

[general]
accept_outofcall_message=yes
outofcall_message_context=dialplan_name
auth_message_requests=yes

extensions.conf

[dialplan_name] exten => _XXX,1,MessageSend(sip:${EXTEN},"${CALLERID(name)}"${MESSAGE(from)}) [/dialplan_name]

When i try to send a message from one user to another using blink softphone i get:

[Jan 29 19:26:08] WARNING[7178][C-0000000b]: chan_sip.c:10515 process_sdp: Insufficient information in SDP (c=)... [Jan 29 19:26:13] WARNING[7043]: chan_sip.c:4109 retrans_pkt: Timeout on 0348c4434d0714f5433456675b558b69 on non-critical invite transaction.

Can someone help? My setup looks like so:
