[Asterisk-Users] Monitor DTMF problems

[Mir]

Hello

We have discovered a problem with DTMF on Asterisk.
We have a setup with a T1 from PSTN going into an Asterisk box, and
then out again on T1 and into a normal PBX (EADS)

We use it to record all calls going to/from the PBX.

The problem is that when we record the calls (with MONITOR command),
DTMF tones gets obscured, and is not understood in the other end, if
we dont Monitor, there are no problems.

It sounds like the tones are cut into two, hmmmm hard to explain ...

Does this ring a bell at anyone ?
