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. -- Arturo D?az -------------- next part -------------- An HTML attachment was scrubbed...
