Hi,
i have set some extensions with SPEXI

IR=XXXXX,OPT=N,NDC=YYYYYYYYYYYYYYYYY;
where XXXXXX is the extension and Y you can see below an example from ALEX:
2.1 FORMAT
2.2 FUNCTION
The parameter states the complete, translated number for an abbreviated number.
A represents * and B represents #.
In the case when a PTS signal is to be detected, its place in the complete number shall be stated with C, D or E.
C Normal PTS. If time out occurs the sending of digits are continued with the same type of register signalling as before time out.
D PTS followed by DTMF sending of digits. If time out occurs the sending of digits are continued with DTMF register signalling.
E PTS followed by DTMF sending of digits. If time out occurs no more sending of digits and the external line is disconnected.
2.3 EXAMPLE
The non-dialled connection number shall be 0005C11E13D11675. The non-dialled connection number complete translated, shall consist of the route access code 00 and destination code 05 and after destination code a PTS is expected.
When a PTS is received or time out expires, next digits shall be 11. After digits 11 a special PTS signal is expected followed by DTMF digit sending, if time out expires the external line is disconnected.
If the PTS is received next digits shall be 13. After digits 13 a PTS signal is expected and if time out expires DTMF digit sending is performed. After that next digits shall be 11675.
NDC = 0005C11E13D11675
This on the BC11/sp12
