akawoz: I'm, having a similar issue. When I phone out to a mobile from my VFX line the mobile continues to ring for 10 seconds.
I have a Linksys PAP2T, the router is a Linksys WAG325N, I'm forwarding the following ports (all UDP) to my PAP2T:
5060 - 5061
53
69
10000 - 20000
Any ideas? If this could be a NAT issue, should I put the PAP2T in the DMZ?
BTW: this is day #1 with Fusion so excuse my ignorance ;-)
same as the issue i had, for cell phones it cuts out after 10 secounds after you hang up, try a land line it will just keep ringing :(, my issue was i was using the router in access point mode, and the modem did not support the PAP2 as soon as i put the router into its orignial router mode no more issues,
i agree with mavric take off portforwarding at least from your router,
