No LNP insertion
- No LNP field is inserted in the outgoing leg. (Default).
Relay LNP information
- LNP fields are inserted in the outgoing leg only when they are received in the incoming leg.
Always insert LNP information
- LNP fields are inserted in the outgoing leg regardless of their presence in the incoming leg.
The following table contains the pseudo-code of the mapping to the outgoing call according to the configuration AND what was present in the routing script variables:
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
| Outgoing NAP config. | Outgoing SS7 | Outgoing SIP |
|---|---|---|
| No insertion | bitM = 0 if ported_number then
else
|
RN and ndpi not present if ported_number then
else
|
| Always | bitM = 1 ported_number => GAP called => CPN |
ndpi=yes if ported_number then
else
|
| Relay | called=>CPN if ported_number then
else
|
if ported_number then
else
|
