Obihai,
The following rules are all valid in an InboundCallRoute:
{pap2>(Msp1):sp1}
{pap2>(Msp2):sp2}
{pap2>(Mpp):pp}
{pap2>(Mli):li}
{pap2>(Mtg1):tg1}
PrimaryLine may be set to sp1, sp2, pp, li, or tg1.
The following rule is ignored in an InboundCallRoute:
{pap2>(Mpli):pli}
I don't know if this is a bug or simply an inadvertent omission (you forgot to expand pli in InboundCallRoutes), but it needs to be supported so that changes to PrimarlyLine don't also require editing to InboundCallRoute rules.
Can we please get this fixed/added in the next firmware release?
