Gatekeeper with several gateways design

1. In a VoIP configuration with multiple remote sites and a gatekeeper, how does the remote site know what are their E164-IDs to send when registring? Does the router assume the "destination-pattern" from all the "dial-peer voice XX pots"? All FXS, FXO, E&M and E1?

2. With just one zone with several gateways, how do i define a prefix to a gateway? Can't use "zone prefix" without "zone local" and i want just one zone.

3. Is there a configuration example of a case study with VoIP, a gatekeeper and several remote sites? The only one i found (the Raleigh/San Jose example) was w/ only one remote and one gatekeeper.

Re: Gatekeeper with several gateways design

I saw and read that docs but there's no info on configuring several gateways with one gatekeeper.

I have 100+ voip gateways. We run GK with this. If you would like I can email you a sample of what we have. We only have one zone. My email is

Re: Gatekeeper with several gateways design

Trae, what tools do you use to monitor such an amount of gateways?

For example, whether PRI-s are up, what is ASR ratio, is any destination overloaded, accounting, ...

Re: Gatekeeper with several gateways design


Has i understood, they don't have any PRIs installed. Only FXS. And that's why the gw, when regstring, send E-164 IDs with the dial-peer POTs they have.

So you know if there's a way to do it when you have E&M, FXO, PRI or BRI?

Re: Gatekeeper with several gateways design

Hi Telmo

We have VoIP setup with few Gateways and a Gatekeeper. Calls coming to Gateways are from GK but send directly to our provider. In FXS yes they do use the E-164 for registration with GK but in FXO (connected with PRI) case we have to use the tech-prefix ( its not the dial-peer tech-prefix but used under the config of the Gateway setting). I have done the Gateway and Gatekeeper setting but i am not sure its the optimal setting or not. Sample of my config is here please correct me if i am wrong or if someone have the better experience. help will be appricated. Thanks
