I switched over to using incoming calls with callcentric and outgoing currently as well callcentric.
I like that callcentric is 2 bucks for unlimited incoming calls and that works well and I'm on pay as you go outbound but I wanted to be able to dial a special number for using google voice when I don't want to chew up my callcentric minutes.
Here is my current outbound route
{911:sp2},{([1-9]x?*(Mpli)):pp},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**9:>(Mpp)):pp},{(Mpli):pli}
I originally had callcentric for 911 and never used it but callcentric is still on sp2 and I now want to have GV as my secondary option.
