Materials :

great news, for the incoming as i mentioned all you need to configure is the incoming CSS and the significant digits under the GW config


the CSS needs to reach the phones and the significant digits how many are you going to use


ie, if you receive 10 digits but you only use the last 4, set the significant digits to 4.


if you already receive 4 and have DIDs then there is really no need

in first place configure the gateway using MGCP or H323


for outgoing configure a route group and add the GW

then create a route list and add the route group

create a route pattern and assign to it the route list


for incoming configure the significant digits and the incoming CSS to reach the phones


if H323 make sure you have the necessary dial-peers configured


you can go thru this doc for a better understanding

Hi


Thks for this document.

In your reply i cannot understand what you mean by "for incoming configure the significant digits and the incoming CSS to reach the phones".

Could you please be more explicit ?


I use a MGCP Gateway, so do you mean that all configuration about 'dial-peer voice' in the voice gateway are irrelevant ?

MGCP does not use voip dial-peers, go to the GW or endpoint config in CUCM and you will find those parameters

Hi,


I'm trying to configure a route group, but there is no device in the Available Devices list box.

The voice gateway is still well registered in the CCM. Is there something missing in gateway parameters ?

Hi,


I have resolved the problem. A previous route pattern not well configured was using this gateway. I have sorted this out. Now i can make outgoing call. I'm trying now to configure incoming call.
