[VoiceOps] VoIP - Call forwarding issue

[Rod.Dossouvi.CTR at dot.gov]

Here is the deal: 
user is trying to have calls forwarded to his cell phone. When enters: 
9-xxx-xxxx, local callers get forwarded fine, but long distance callers
get an error. 
Alternatively, when user enters: 9-1-615-xxx-xxxx, long distance callers
can now get through, but 
local callers get the same error.

Any input? Thank you.
