Suppressing calling party number
« on: July 02, 2013, 12:57:45 PM »
I have a customer with a 3300 and the phones are all ending their DID on outgoing calls. Is there a way that I can suppress sending the CPN on a per call basis?

What trunk do you use to dial out? For SIP trunk it can be kind of tricky and it depends on how the SIP provider how they handle the calls with the hidden caller ID. We have one that requires a special prefix to be dialed e.g. instead of 9+DDI number you dial 9+code+DDI number. Another require a special DDI that the calls are going from. Another requires "Anonymous <sip:anonymous@anonymous.invalid>" in From part of the SIP INVITE message.

You can suppress all CPN or allow it to send the billing number or allow it to do as it does now. However its global not on a per call basis. Its all or nothing. So No CPN at all or main number on every call or DID on every call. Strictly with CPN substitution you can choose on a per extension basis whether to allow main CPN or DID CPN but you cant withold CPN of one or the other. Otherwise its withold CPN on all extensions.

Check with your carrier

Here we use the prefix 1831.

We use 0 for an external line so I created a new rule that hides the number when you dial 0*

I would think that with some kind of list, cor setup you could use call by call service to send unknown caller

If you want the select when a call sends the BTN and not the individual DID you could build a multicall for this and use associated directory number to mask it.

You will have to enable Non-prime Public Network Identity in the COS and of course you would have to select the multicall before dialing to show the alternate number.

I think Mattmayn's answer will be the simplest to do.   
One change in the COS and one add in the the associated directory number form.
