Hey guys,

I need help to identify the cause of this is error:

Jun 26 12:03:53 ashintgtpsg51 /usr/sbin/kamailio[1651]: ERROR: tm [t_fwd.c:1728]: t_forward_nonack(): no branches for forwarding


This message was shortly printed after I xlog a message in onsend_route[] block.  What else is strange is that the dialog continued on with that same SIP Call-ID.

This is what it looks like in the wireshark flow diagram:

The dispatcher entry is an SRV record which lists available hosts.

Any thoughts on how I can identify the cause of this?

Thanks.
