Note 1:
The Relationship between physical ports and Interface Ids is as follows:
FXS 1 = IF:06
FXS 2 = IF:07
…
FXS 8 = IF:13
FXO 1 = IF:56
FXO 2 = IF:57
H.323 LAN = IF:05
Note 2:
For calls from H.323 to the telephones, the H.323 gatekeeper must present a 3-digit
extension number, whether the caller dialled just the extension number, or whether the
caller dialled the full telephone number (including area code).
For the call to be accepted, the last two digits of the extension number must be 06 to
13 to be a valid Vega FXS interface ID.
For calls from H.323 to the FXO lines, the gatekeeper must choose the appropriate
interface on the Vega to dial out from; when the gatekeeper presents a call to the Vega
the telephone number field must contain
ppttt…t
where
pp
= port number (56 or 57)
and
ttt…t
is the telephone number to onward dial.
For more details on the operation of the dial planner, including the various
tokens that may be used, see the section “The Dial Planner” in the Vega
Primer.
