FWIW, here is the configuration I use on SP2 for Anveo:
Service Providers -> ITSP Profile B -> General -> Name : Anveo
Service Providers -> ITSP Profile B -> General -> DigitMap:
(<1aaa>[2-9]xxxxxx|<1>[2-9]xxxxxxxxx|1xxxxxxxxxx|011xx.|(Mipd)|[^*#]@@.'@'@@.)
where aaa is your local area code.
Service Providers -> ITSP Profile B -> SIP -> ProxyServer :
sip.anveo.comService Providers -> ITSP Profile B -> SIP -> ProxyServerPort : 5010
Voice Services -> SP2 Service -> X_ServProvProfile : B
Voice Services -> SP2 Service -> AuthUserName : (sip username)
Voice Services -> SP2 Service -> AuthPassword : (sip password)
Voice Services -> SP2 Service -> CallerIDName : (callerid name)
