Customer has three of these SVR3000 devices for other clients, they are using PHM1200 Ip phones, on the display of the phone it states that they cannot make outbound calls but in actuality they can make calls, also when trying to do call forwarding there is no audio until they put them on hold and pick it back up. I asked him a few basic questions:
Is this a first time implementacion?No
if not has it ever worked before?Yes
Do you have internal firewall services? yes
Do you has IPS firewall features?? no
If so can you turn everything off and try making those calls then? yes
Do you have QoS implementacion in your network? yes
Do you have access control lists or access rules applied to this network? Yes
What other devices if any are in your telephony network? (routers, switches, etc) routers and switches
What kind of internet connection do you have? Cable Modem? Dsl? Leased Line? DS-3’s
Is your provider information configured correctly? yes
Any hints pointing in the right direction will be much apreciated thanks in advance.
