Dear all,
I am having seriuos problems getting VoIP traffic into and out of my network
via the ISA server which we just newly installed.
My requirement is for users to have internet access from the ISA Server
itself, and i have enabled browsing from the Local Host Network, set the
browser settings, and included the sites in the System Policy Allowed
Sites. And it is working perfectly.
The big problem still remains that my IP phones cannot register to my proxy
server sited at some remote location outside my LAN.
My network topology is such that the phones i am using for the VoIP service,
sitting inside my network and behind the ISA server, have to register to some
remote proxy server outside my network and as soon as it registers i can
begin using the service. The VoIP service is on the platform of SIP and uses
udp ports 5060 and 8080.
I have permitted the necessary ports on the ISA server for the service being
UDP port 5060 and 8080 but still cannot get my VoIP traffic through the
server.
The main question here is: Just as i did including sites in the systems
policy Allowed site, is it possible including the IP address of the SIP proxy
server with some remote IP address like 81.203.23.213, to which my phones
should register to?
Please i need some help here as regards something i am supposed to do or
something i am not doing correctly.
Leonard
