Results from that might be a bit hard to predict with two phone port OutBoundCallRoutes and 011xx in Mpli in both. The great digit map guru of the distant past recommended leaving phone port digit maps and outbound call routes alone
If you are starting from default with sp1 as your Primary Line, then change ITSP A DigitMap (Msp1) from:
(1xxxxxxxxxx|<1>[2-9]xxxxxxxxx |011xx.|xx.) to this:
(1xxxxxxxxxx|<1>[2-9]xxxxxxxxx |<**3>(011xx.)|xx.)
This will add **3 to any number starting 011, then either of the outbound call routes will send it out via sp3 after first removing the **3.
