Apologies if this has already been answered. Teething children = no sleep, and complete lack of brain power......

I have Elastix setup and working with two trunks.

Trunk 1 is to my old Samsung PBX which runs the majority of my phones.

Trunk 2 is to my VoIP provider, and is currently used for external calls from my SIP handsets.

We are in the process of removing our old analogue lines, so need the Samsung PBX to send all external calls through the Elastix box.

I've had the Samsung end configured - Dialling 9 and then the external number now goes to the elastix box. But it is being picked up by a "Catch All" rule and being sent to an IVR.

How do I tell Elastix to route calls from Trunk 1 starting with a "9" to Trunk 2?

I've looked at the Custom Context module, but have gotten lost.

Thanks in advance for your help and patience.

You will need to change the trunk context from from-pstn to from-internal, this means that you have already configured your outbound routes.
