LibPri 1.4.15 add new Dialing plan

Good day!

Our provider requires that in the “Called Party Number” transferred TON: Unknown (0) and NPI: ISDN / Telephony Numbering Plan (E.164 / E.163) (1)
No standard dialplan from libpri does not fit.
Is it possible to achieve the desired through the standard configuration?
Or need to patch libpri?
