I have IPO connected to SIP provider with trunk, on the other side i have third party switch connected with ISDN trunk.
I need one DDI number from SIP procvider to be routed to ISDN trunk. In short when somebody calling to SIP ddi i need to pass this call to third system via ISDN trunk.
Now on user xxx i have Call Forward Uncoditionall to number 61xxx where 61 is the accesss code to ISDN trunk but calling number is not passed via ISDN trunk.
Is there any way to setup this correctly? I think Incomming Route propably but i dont know how to set up to call ISDN trunk from SIP trunk.
