I have two voice gateways :
1) A 3660 ( version 12.3(2)T) in the home office.
2) and 2620 (version 12.2(29) in the remote site with two FXO card.
In the remote site, I want make call locally and if these 4 lines busy or there is another problem, to route calls to voice gateway in the home site. For this, i have used two ways :
1- configure many (4) pots dial-peer (
To the PSTN) with the preference 1
- configure 1 voip dial-peer to the
gateway in the home site with
prefrence 2 and same destination as
2- Configure ,in the CCM, a Route list
with a Grouplist that contain these
two gateways as H323 gateway . ( the
remote voice gateway is the fisrt in
But, with these two config i have always a busy tone if the 4 line ( 4 FXO ports) are busy !!
Please, how to resolve this situation ?
Check your remote site H323 gateway configuration in CCM. Do you have a calling search space with permissions to call the PSTN? Is the Significant Digits set to All (or at least the number of digits sent from the router)?
If the config is good try a reset on the gateway.
The problem is not with the PSTN calls. I make calls to PSTN locally in the remote site (4 FXO ports), but when these ports are busy, i want to route next call to VG in the home site across voip dial-peer.
I have used route list also, but didn't much.
Standard gateway images, like IP Plus allow you go go from inbound pots to outbound pots, and inbound voip to outbound pots dial-peers.
You need IP-to-IP Gateway software to go from inbound voip dial-peer to outbound voip dial-peer.
Can you elaborate on the the route-list / route-group configuration that failed?
