Hi, Does anyone know what exactly the option transmit_silence_during_record in asterisk.conf does? Is this useful for voicemail recording? Providers such as Broadvoice and Vonage hang up the channel after 30 seconds because they think the other party is not there when someone records a voicemail. I've been using rtpkeepalive=15 in sip.conf to overcome this problem but I am wondering if this asterisk.conf option better serves this purpose? -------------- next part -------------- An HTML attachment was scrubbed...

If asterisk sends nothing while the caller speaks his message, the provider might terminate the call. So asterisk can transmit silence (which is not "nothing") during record. Similarly you might have to say "yes dear" regularly to avoid having the connection terminated while talking to your SO. :-) Leif

Yes, it does _exactly_ what it says it does but the usage of the option remained elusive to me.
