Is it this easy?
In the phone OutboundCallRoute setting:
{([1-9]x?*(Mpli)):pp},{(<#:>|911):li},{**0:aa},{***:aa2},{(<**1:>(Msp1))|155555555|14444444444:sp1},{(<**2:>(Msp2)):sp2},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
Where all calls would go out the primary line (in my case the PSTN) except for 15555555555 and 14444444444. Those would be routed through SP1 ?
Thanks!
