Has anyone ran into issue where IP Phone calls between 2 sites over
internet with site-to-site VPN? On the first call the audio is one way
but if you hang up and call right back the call works fine with audio
in both directions.

Main site is an ASA and remote site is a Cisco router. All subnets are
allowed for the the VPN traffic.

Erick
