Has anyone configured polycom viavideo(LAN based h323 clients) talking through IP/VC 3520
gateway onto WAN h320 nodes
Present scenario : IPVc 3520 LAN gatewayip is 192.168.20.58 WAN side only one BRI
connected and assigned a numberISDN
gateway configured to use embedded gatekeeper
gatekeeper pemanent zone file entries mapping ip to extension numbers
Callrouting inwards tcs4
Polycom viavideo clients configured to use gatekeeper and H323 extension which
matches extension numbers in zone file of gatekeeper
STill cant get this thing to work...initially when we had automatic registration we got errorr"duplicate aliases in Gatekeeper"..we have removed the same now and manually entered h323 lan endpoints in the zone table of gatekeeper..now it registers but "service not found "
Can anyone define
the exact workflow of a call being placed from LAN to WAN and viceversa
When WAN places a LAN call...is it the gatekeeper that routes the call inward??
You should kill your configuration and start from scratch.
1. enable the embedded GK
2. Configure the gateway to registerer with embedded GK address (same address used for the gateway)
3. Configure a service prefix for outbound calls (example 9) to dial outbound you will dial 91<10-digit ISDN number(s)>
4. Enable IVR only on the gateway for inbound call routing (this allows you to test and verify that the gateway is answering the inbound calls correctly)
5. Configure H.323 extension on your Via Video (example 55555)
6. Configure Gatekeeper address on the Via Video (gateway IP address)
Reboot gateway and client. Make sure the gateway and endpoint are listed in the gatekeeper registrations (do not hard code anything). Also make sure that the gateway service prefix is listed in the service table.
7. Go to the Via Video and try dialing out using the service prefix and ISND number(s).
8. Dial inbound to the gateway from ISDN (you should get the IVR) after the IVR answers enter the Via Video's h.323 extension (55555) followed by the # sign.
You shouldn't manually configure any endpoint information in the Gatekeper. In the gateway configuration you will enter its own IP address.
You should have all endpoints (including the gateway) register with their information, you don't need to manually enter any endpoints in the GK.
Followed by the # ....
Hardcoding GK information makes it very easy for calls to fail because something has been changed on the endpoint of a fat finger during config. I
If you set the unit back to factory defaults "I believe" Plug and Play" all you should need to do is enable the GK, and reconfigure the gateway paramaters. Just make sure you gateway service preifx is listed in the services definition talbe. I don't have a 3520 or 3510 at my disposal so I am doing this from memory... Sorry.......
We are running the latest version of Via Video & have noticed that it always picks a different port each time it registers with the gatekeeper (3520). Therefore we do not hardcode the terminals in teh gatekeeper.
Some other devices we use are consistent in the ports they use, and we have predefined some of them.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
