How to Specify *97 in OutboundCallRoute

[DwayneM]

I have SP1 as Google Voice, and SP2 as voip.ms with SP1 as my primary service provider for outbound calls.

voip.ms allows *97 to access one's mail box, how do I redirect the dialing of *97 to be directed to SP2 ?

Tried adding
{*97:sp2},
to the beginning of the OutboundCallRoute but it gets flagged as an error with a red exclaimation mark.

Yes, I know that I can just dial **2*97 without having to mess with the OutboundCallRoute parameter.

I set up a star code to do this:

Star Code Profile A -> Code?? -> *97, Voice Mail, call(**2*97#)
