Let me tweak Ron's instructions (I realize how presumptuous it is on my part
).
I am also assuming Google Voice on SP1 and VoIP Raider on SP2.
Physical Interfaces -> PHONE Port -> PrimaryLine : SP1 Service
Voice Service -> SP1 Service -> X_ServProvProfile : A
Voice Service -> SP2 Service -> X_ServProvProfile : B
Service Providers -> ITSP Profile A General -> DigitMap : (<1813>[2-9]xxxxxx|<1>[2-9]xxxxxxxxx|1xxxxxxxxxx)
Service Providers -> ITSP Profile B General -> DigitMap : (xx.)
It's easier to understand that you set up VoIP raider dial plan settings in
ITSP Profile B section - same place where you set up your SIP credentials, STUN server, etc. Added benefit is that Ron's plan assumes that international numbers start with 011 - which is not always the case! Specifically, voip raider - as all betamax companies - requires that you dial 00 instead of 011. If that is the case, you may change the last option to
Service Providers -> ITSP Profile B General -> DigitMap : (<00>xx.)
Note that neither GV nor VoipRaider support 911.
