Hi! Sorry, I was sick last week...
because of the flag for socket matching, record matching (ip, socket) is selected. Is this the desired behavior.
Yes, this is the desired behavior, because we can only have a target with an ip and socket like this (it seems to be a valid configuration):
70 sip:192.168.1.1 0 1 route=route 1;sockname=udp_5060
Somehow, it should be clear in the documents how the destination record is selected.
I understood, I will supplement the documentation more fully on this occasion.
