[VoiceOps] Verizon and E.164

What type of product are you using for SS7 to/from SIP translation? There is a 
good chance that your SS7 to SIP translation device may have the ability to 
manipulate ANI and DNIS as required. In the application we use on our net the 
M3UA server manages E.164 vs 10 Digit National decisions quite well.

Also, do you plan to use this SS7 route for any international termination? If 
not, it might be as simple as limiting all calls over that trunk group to 10 
digit ANI/DNIS outbound then prefix a (+)1 on the inbound.
