We have an AudioCodes MP-118 gateway and a nexVortex VoIP line. Currently we are using the gateway for inbound calls and the nexVortex line for outbound calls and that is working fine. We would like to have the gateway working for both inbound and outbound calls if possible so we have it to fall back on if our Internet connection ever goes down but we are having problems getting outbound calls to work on the gateway. When I try to make an outbound call on the gateway it just rings and rings but never goes through and connects. I am not sure if this is a gateway problem or an Elastix problem so any help you all can give would be greatly appreciated.
