Good Day All,
I am experiencing some weirdness using the E&M channel and hope
you can offer a little assistance with the problem I am having.
1) call comes into channel 25 (Second Span first channel of a Digium
Quad PRI from SBC-PRI)
2) Call is sent to channel 1 (First Span first channel on the Digium
Quad PRI connecting an ADTRAN via E&M Feature Group D)
3) Between rings one and two the DNIS and ANI is sent then the unit
answers the call.
I barge into channel 25 and listen in on phone 1
I Barge into Channel 1 and listen in on phone 2
PHONE 1 )While listening in to Channel 25 I get the following:
1) I hear two rings
2) I hear the IVR System on channel 1 answer the call
3) I hear the IVR System request the account code
3) I hear the remote unit send (16 DTMF CODES RAPIDLY within a 2
seconds)
Phone 2) While listening in to channel 1 I get the following
1) I hear the IVR System answer the call
2) I hear the IVR System request the account code
(note the above 2 things were heard simultaneously with
phone 1)
3) I hear the DTMF (account Code) come in however it takes many
seconds longer than what was heard on Phone 1
Phone 1 hears 3 sets of DTMF Codes before Phone 2 hears
even the initial 16 digits (the remote unit sends the codes 3 times if
there is no response after each attempt)
The problem is that the IVR System expects these DTMF Codes with the
initial 2 seconds.
The DTMF Tones from the outside caller are heard appropriately on the
inbound channel (25), however when we (bridge them) to Channel 1 the
tones are
heard much slower causing the IVR system to refuse the caller.
MAtt, I am trying to figure out how or where asterisk is messing with
these codes?
