Dear All ,
I have this Case , There is a customer has HQ and Branches in the HQ there is SV8100 in HQ and they want connect remote IP phones in the Branches
The Topology of network I will describe between HQ and one branch because this topology applied the same with all branches
There is Router behind PABX and there is Router behind IP phones The connectivity between them SHDSL and there is static Router applied in two router to make the two location as one network
my Problem the IP phone can't connect with PABX " SIP Server Not Found " although i am already upload NAPT license on the PABX but without port forwarding in two routers because they unconvinced they need to do port forwarding because they are one network and they are many applications working on this environment without need to port forwarding and the IP phone was working suddenly stop after this i suggested we need to NAT
Any one can help me in this issue
