Block inbound calls from anonymous numbers on SIP 1

[PaulCarter]

Hi,

Our customer wants to block calls from anonymous numbers on a couple of their DDI's. I know I have done this previously on ISDN using a ! in the incoming CLI on the incoming call route to route them to a barred shortcode but this doesn't seem to work on SIP. Does anyone have any ideas on how else we can do this?

Try to enter anonymous in the CLI field.

IP Office remote service
IP Office certificate check
CLI based call blocking
SCN fallback over PSTN

That's great - that worked!

Thanks
