Some time ago, there were folks looking for a way to "broadcast" a voice messages to PSTN based voice mail services. The short-of-it is that they were stymied but vast differences of greetings and potential instructions that played when the various voice mail services answered and thus could not accurately gauge when to play broadcast message. Broadcast messages left on the various voice mail services were typically truncated to some variable point from the start of the message.
If there is still interest in such an application, I've figured out fairly simple, elegant and reliable solution using opbx_dsp_silence() to gauge when all the "noise" finally stops and it is safe to play the broadcast message. At this time I've tested the solution with voice mail services provided by Clarity, Cox, Qwest, SBC, Cingular, Verizon and Vonage. Anyway, if there is any further interest I'll be happy to share how it was done. _______________________________________________ Openpbx-dev mailing list [email protected] http://lists.openpbx.org/mailman/listinfo/openpbx-dev
