This seems to be a bug in R2 chan_dahdi support.<div><br></div><div>The problem is that the audio that you hear during the voicemail prompt ("Por favor deje su mensaje ... blah blah"), is sent as "early media". In MFC-R2 there is really no signal to notify whether inband information is available, the call is just accepted. I am unsure if typically all telcos provide alerting information, the R2 support in Asterisk has been working without major complains for a while, so I don't want to break backwards compatibility by adding inband media to all calls.</div>
<div><br></div><div>To fix this I think a new configuration is needed, something like mfcr2_media_on_accept=yes or something along those lines. This would mean when the call is accepted (but not answered) media will be passed through instead of waiting for the answer signal. That should fix the problem with voicemail in the telco.</div>

Are there any news on this subject. From the slin files I can hear the Telmex prompts but we can't still hear them on the phones, it doesn't matter what configuration changes we made
