I currently have an old CUCM system that is unable to dial any mobile number that starts 073.
I'm assuming that this is down to an old dial plan being installed. As this box no longer has any support on it (due for retirement soon) is there anything that I can do in the meantime?
There's no way to tell if this is on CUCM or on the GW without reviewing the dial plan configured in CUCM, and if using H.323/SIP the config on the GW as well.
You can start by either reviewing your route plan report, or using DNA to find out how you're routing those calls.
For some reason DNA is not letting me select options. I'm just restarting those services now. If it helps, as soon as I dial 9 (outside line) 073 I get a message saying 'the number you have dialed has not been recognised, please contact an operator or try again'
does that sound like the GW ? the dial plans are pretty basic.
That doesn't sound like CUCM, debug the GW to see if the call makes it that far, and if you see the call there, most likely that's your telco playing that message.
But there must be something in CUCM which sends the calls to the GW as soon as you dial 9073, and that you would need to fix.
just done a DNA and got:
Match Result = RouteThisPattern
but as you say there must be something that is pushing this as it is immediately after the number 3 is pressed (4th digit)
