[asterisk-users] mISDN DTMF endless tone

[Arturo Díaz Almagro]

Hello all,

I have set up a server with an OpenVox 1BRI card using mISDN driver and
asterisk 1.4.22. All things works properly except when dtmf tones are sent
from PSTN and to PSTN. The cases are different:

- from PSTN, when the end user press a digit I got that right via mISDN
(seen with ISDN asterisk debug) but asterisk is reproducing the tone endless
breaking completely the conversation.
- to PSTN, the phones are sending both inband and INFO dtmf tones, and they
are "played" twice in the PSTN end. Is there anyway to send only one
although two were sent?

The case from PSTN is the most anoying because it is interrupting the
communications. Do anybody have any idea of what is going on?

Thanks in advance.
