A certain PSTN number is constantly dialling one of our ddi's day & night from an autodialler & I'm not having any luck stopping this at network level. Is there a way to block or reroute calls from specific numbers on UX2000?

I'm not sure about the UX2000 but you could write an MSPL script to achieve this. See here.

Yes, you can manipulate incoming calls from the UX2000. I am not certain about blocking but you can indeed reroute the calls from a specific number.

I have now figured out how to do this and managed to block the calls, if advice required let me know

Hi,

Please check if any black list can be configured in the UX2000 to block the specified incoming call.

I'm running into the issue.  How did you end up blocking the call from the UX2000?

thanks!
