Unable to transfer "Anonymous" calls off switch?

[anthonymo]

IP500 8.0(18)
When a call comes in and the CID is presented we are able to press transfer, dial 9 then an off switch number and transfer the call without issue.

However if a call comes in marked "Anonymous" (thru dialing *67 or carrier blocking) and we try to transfer it we get a call rejected message. I'm guessing I need to modify either a dial code or a SIP URI, Let me know if you need further info !
I've ran the Monitor and captured the following bit of data
10.1.1.114 is the IP500
3809090 is my cell
207.5.178.218 is the SBC
69.39.99.162 is our Wan address

My experience with this is the LD carrier will not allow a call to go out that is not in your block of "authorized " numbers. Some allow it, some don't as a 'security' measure. Having said that, I don't know how to gewt around it. Have you called your carrier?

 

[anthonymo]

Yes, I spent about an hour on the phone with them yesterday only to have them confirm that the "anonymous@anonymous.invalid" was causing the issue and they couldn't correct it.
I was hoping for some sort of 'Don't used called # when trasfering call' option

 

[anthonymo]

Anybody else have an issue transferring CID blocked calls?
If not can you show me the trace so I can see the difference, perhaps we can discuss URI settings?

 

[anthonymo]

Anyone? I guess this isn't an issue?

When you transfer the call, just send it out via an ARS that withholds the number, or simply presents a valid number off your number range?

Here is how I set it up:
When they press transfer and dial 9 it triggers an ARS that matches N; to N Line group ID 7
Line 18 (SIP) Channel 1 is outgoing line group 7 (the only one) its local URI, Contact and display name are all the same;
8665516300 (number changed)
If the operator was to start a new phone call and dial 9 it works correctly and represents the 866 # however if they are transfering a call we run into that From: "Anonymous" <sip:anonymous@anonymous.invalid> error.

Please be gentle, my only training was the intro stuff 5 years ago needed to become a certified installer. SIP and ARS was hardly around then
