we have a new ASA and want wo communicate via some Cisco SPA509G phones over sipgate.
Following Problem: whitout STUN activated in the phones i get the following error in the ASA Log:
4 Jun 14 2010 07:00:37 507003 192.168.100.67 5060 18.104.22.168 5060 udp flow from inside:192.168.100.67/5060 to outside:22.214.171.124/5060 terminated by inspection engine, reason - reset based on 'service resetinbound' configuration.
and when i activate STUN server i can accept incoming calls from outside, but can not hear something from outside caller but the outside caller can.
With activated STUN and Outgoing call same problem the other way: i can hear nothing but the external can.
Thx for any solution idea.
