We are using an Obi 312 for the FXO Port and need to be able to do 2-stage dialing when calling out over the PSTN.  We cannot find setting to allow us to go off hook on the FXO port without dialing a number.  Does anyone know what setting needs to change for this to be allowed?

I just used ## from the built-in default OutboundCallRoute on the "Phone1" physical interface. But there may be other options as listed below as well, hope this helps!

 

OUTBOUND CALL ROUTE:

{([1-9]x?*(Mpli)):pp},{(<##:>):li},{(<**70:>(Mli)):li},{(<**82:>(Mbt2)):bt2},{(<**81:>(Mbt)):bt},{(<**8:>(Mbt)):bt},{**0:aa},{***:aa2},{(<**1:>(Msp1)):sp1},{(<**2:>(Msp2)):sp2},{(<**3:>(Msp3)):sp3},{(<**4:>(Msp4)):sp4},{(<**9:>(Mpp)):pp},{(Mpli):pli}

 

From the poly-obi3-obi5-ag-en.pdf (ADMINISTRATOR GUIDE - Poly OBi Devices - OBi3 and OBi5 Series)

 

Invoke a Second Dial Tone in a Digit Map:


You can tell the device to start a tone after a certain pattern of digits have been dialed by specifying the element {t=<tone>} within a digit map, where <tone> is a 1- to 3-letter name of the tone to play. The tone stops when the next digit is entered.

 

For example:

 

(**1{t=di2}(Msp)|**8{t=od}(Mli))


tells the device to play Second Dial Tone when **1 is dialed, or play Outside Dial Tone when **8 is dialed.


Here is a full list of acceptable (case-insensitive) values of <tone>:
bu = Busy Tone
cf = Call Forwarded Dial Tone
cm = Confirmation Tone
co = Conference Tone
cw1 cw10 = Call Waiting Tone 1-10
di = Dial Tone
di2 = Second Dial Tone
fb = Fast Busy Tone
ho = Holding Tone

od = Outside Dial Tone
pr = Prompt Tone
rb = Ringback Tone
ro = Reorder Tone (same as fast busy)
si1 si4 = SIT TONE 1 – 4
st = Stutter Tone
0 – 9, *, #, a – d = DTMF 0 – 9, *, #, A – D
