Hi All
i have a very strange issue with SIp over my vpn
we have several home workers using an avaya app as a sip phone
they can all ping their relevent phone system with out any latency and can make calls to land lines 99% of the time
the issue is when connecting to a mobile it is connecting but no voice can be hear either end
doing a trace of the data packets landlines get passed to gamma (our SIP provider)
when it comes to mobile it states pending
i have tryed a router with the VPN certificate installed and this can reverse the issue so we get mobile connect and not land line but again this is intermittent
just to gove all info we do use nat on both ends and have not poened to port for STUN yet or set it up on the phone system routers being used are edge router 12 & edge router x not that that makes any differenct i beleive
i hope someone can help
Cheers
Shaun
