Hi all,

I am trying to withhold number on SIP trunks via IP office as the SIP providor can not guarantee the 141 prefix will work all the time over the VOIP network.

The only setting i can see is on the SIP line - send caller ID - set this to 'None', however it still pushes through the number. Is there any other suggestions?

IPO R8.1

Thanks
 
We use the W character ISDN style and it works, with some SIP providers inserting "Anonymous" also withholds the number :)
