Terminate LNP

  • Routing is done using the real called party number (not the LRN). LNP fields are ignored for the outgoing leg. (Default)

Forward LNP from incoming to outgoing call

  • Routing is done using the LRN when available otherwise the called party number is used. LNP fields are kept for possible relay on outgoing leg.

Ignore LNP information

  • Routing is done using the called party number. LNP fields are ignored for the outgoing leg.


The following table contains the pseudo-code of the mapping according to the configuration AND the content of the incoming call signaling:
CPN = called party number or the TO sip header
called = called number variable accessible in routing script
GAP = generic address number SS7 information element type 0xc0
ported_number = extra number type accessible in the routing script
RN = rn field in SIP request URI
bitM = SS7 Forward call indicator information element: ported number translation indicator (bit M)
X = drop number
