Hello:
    I followed the step by step guide (
http://kb.asipto.com/asterisk:realtime:kamailio-3.3.x-asterisk-10.7.0-astdb) that describe the realtime integration
between Kamailio and Asterisk. I have no problem with registration but when I try a call from 106 to 107 I get the followng error :
 
1. in the asterisk console:  "
Unresolvable destination (478/SL)"
2. in the kamailio log:
   May  6 17:01:38 WH-PC /usr/sbin/kamailio[4192]: ERROR: <core> [resolve.c:1540]: ERROR: sip_hostport2su: could not resolve hostname: "(null)"
   May  6 17:01:38 WH-PC /usr/sbin/kamailio[4192]: ERROR: tm [ut.h:327]: failed to resolve "(null)"
   May  6 17:01:38 WH-PC /usr/sbin/kamailio[4192]: ERROR: tm [t_fwd.c:1530]: ERROR: t_forward_nonack: failure to add branches
   May  6 17:01:38 WH-PC /usr/sbin/kamailio[4192]: ERROR: sl [sl_funcs.c:371]: ERROR: sl_reply_error used: Unresolvable destination (478/SL)

  
Any idea about the cause of this problem?

ps:kamailio and asterisk are running in the same machine. 
 
ps:attachment is  Asterisk CLI log

Best Regards,
zhengyw
