Yes: Use "bindaddr=192.168.1.102". That's how we solved it on our
Asterisk boxes. Another solution would be to use tcp, but not all SIP
clients support that (and I don't know how good Asterisk does).

Personally, I think this is a shortcoming in Asterisk. Every application
with udp server functionality should handle this correctly.
E.g. FreeRADIUS has a compile time option for this (--with-udpfromto,
unfortunately off by default, for whatever reasons).
