Polycom VS EX and h323 proxy?

Hi....

We have some Polycom ViewStation EX/FX's, a Cisco 2600 h.323
gatekeeper, and a Polycom MGC50 MCU gateway.

Our network is in private address space behind a NAT firewall.

I was wondering if anyone could tell me is there anyway to use a h323
proxy with our PolyCom equipment. As far as I can tell, the Cisco 2600
can be configured as a h.323 proxy, but I don't know how to configure
the PolyCom stuff to use a proxy. Basically, I would like if possible
for all IP based video conferences connecting to external sites over
IP via the internet to have all traffic coming from one address which
would make it much easier for me to secure our net....I would only
need to allow traffic between proxy and internet.

If it is not possible to specifically configure the Polycom gear to
use a proxy, is there any way they could somehow use a transparent
proxy?

Any help much appreciated....

Thanx in advance.

Chris.

Why not use Asterisk (http://www.asterisk.org) and use our h323 channel
driver. Then you would have conferencing, softswitch, voicemail, sip proxy,
number matching, predictive dialer, interactive voice respone server,
billing system, pbx, calling card platform, and etceteras.

It's not a matter of the Polycom having the ability to use a proxy, but the
Polycom having the ability to register with a h.323 gatekeeper. Youre Cisco
router can be configured as a proxy h.323 gatekeeper, so provided your
Polycom can register with the gatekeeper, you can do it.
