A couple of tricks that are possible that might help in different situations:
Using SRV records for gateway selection? I've not tested this yet but should be possible. I have done this... Make DNS at the remote select the local gateway first... ie., site 1: gw1.sip.domain = 192.168.1.10 gw2.sip.domain = 192.168.2.10 site 2: gw1.sip.domain = 192.168.2.10 gw2.sip.domain = 192.168.1.10 Mike On Wed, Jul 6, 2011 at 12:36 PM, Tony Graziano <[email protected] > wrote: > I have two site connected via an IPSEC VPN.
