[asterisk-users] Reception of vocal SMSs to landlines.

This is not a clean or efficient solution, but you could use an AGI or .call
file to sent the SMS as a separate call.

Subject: [asterisk-users] Reception of vocal SMSs to landlines.

Hi all,

we face a problem with SMS reception sended to _landlines_, at least in 
France.

Normally operators -tested with France Telecom and SFR- are sending 
voice SMSs from a particular CID number, so no problem. But today we 
discover that -at least SFR- send from time to time voice SMSs with 
original callerID which means that the call is terminated like a normal 
call and not recognized as voice SMS.

Problem is that we Answer() the call or we forward it or we send it to 
voicemail, each user having his own setup. In such cases, the SMS will 
_never_ be delivered as:

. after we Answer() the call, the operator send immediately the audio 
SMS. At this time we are just parsing dialplan to see what to do with 
the call. If the call is to forward, operator hangup -end of vocal SMS- 
before the called party could take the call.
. if sending to voicemail, with or without Answer(), and as generally 
you send audio before recording (eg "Our office is currently close, 
blabla ..."), during this time the SMS is already readed! You just catch 
the last audio from operator message if introduction is not to long.
. if you Answer() and don't take the call (busy or second line or ...) 
same that for VM: you catch nothing or only the end of message.

Is there a way to detect voice audio before to -at least- send directly 
to a voicemail without announcement? Or is another solution existing?

Thanks for any hint
