Re: Routing incoming external calls. How to do it?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I may be able to help you for a setup that includes a PSTN gateway in
coupling with GNUGK.
We use the same type of set-up for which we include the following in the
gatekeeper.ini file:

[RoutedMode]
GKRouted=1
H245Routed=1
AcceptUnregisteredCalls=1

The important parameter for you is "AcceptUnregisteredCalls". Am not sure
whether the first 2 parameters (GKRouted, H245Routed) need to be set for
this parameter to work. That is, m not sure whether the calls need to be
routed via the Gatekeeper in order to make "AcceptUnregisteredCalls" work.


Secondly, we use audiocodec MP118 for our setup. Within the configuration of
this gateway, we have a setting under:
Protocol Management --> EndPoint Setting --> Automatic Dialing.
In this setting, we have a table that assigns a Port of gateway to a phone
number. Suppose port 1 is assigned to number '123', and 123 is a registered
endpoint (internal endpoint in your case), then all numbers to the line
attached to port 1 would be redirected to this internal endpoint.

Data till now should help.


One overhead step we've taken is to include following section the gnugk ini
file:
[RasSrv::PermanentEndpoints]
192.168.5.XX=GW_ALIAS;84

where 192.168.5.XX is gateway ip, GW_ALIAS is the gateway alias and 84 is
the registered prefix.
Thus, lines on all ports of the gateway and having extension with prefix 84
(e.g. 8467 and so on) would be considered to be permanant endpoints and need
no registeration.

Subject:  Routing incoming external calls. How to do
it?


Hi,

I'm setting up a gnu-gk on a public server (with public IP) and I've
already test successfully external-to-internal calls using NAT, making
both parties to register first with the gatekeeper.

What I want to do now is to route incoming calls from outside (coming to
the public IP) to a predefined host in the LAN, but without making the
external host to be registered with the gatekeeper.

Is this possible? I know little about this subject, and I'm don't know
if I can accomplish this using only gnu-gk.

Thanks in advance for your reply,

Fernando
