What I see it doing is ....it's appending the local area code and it's calling 1-localareacode-7digitnumberdialed via the sp1 interface which is the default on obihai #1.
Here are the digimaps and outbound call routes:
obihai#1
Phone port
Digimap
([1-9]x?*(Mpli)|[1-9]S9|[1-9][0-9]S9|088*******|*******|911|**0|***|#|**1(Msp1)|**2(Msp2)|**8(Mli)|**9(Mpp)|(Mpli))
OutboundCallRoute
{(<200222222*>xxxxxxx):pp},{([1-9]x?*(Mpli)):pp},{(<#:>|911):li},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**8:>(Mli)):li},{(<**9:>(Mpp)):pp},{(Mpli):pli}
obihai #2
obitalk service
Digimap
(<ob>xxxxxxxxx|obxxxxxxxxx)
InboundCallRoute
{200111111>(088xxxxxxx|xxxxxxx):li},{(200222222|200111111)>(xx.):SP1},{(200222222|200111111):aa},{ph}
