Hello Jorge, and thanks for the answers, but:<br><br>I don't understand what is a blind transfer and a supervised transfer.<br>I mean, in the topology:<br><br>- pstn line -> norstar (ext 123) -> ATA -> (fxo zap/1) asterisk
<br><br>An incoming call from the pstn line is forwarded by the norstar to extension 123 were asterisk is.<br>So asterisk answers the call and play a background message for the caller. <br>But when the user enter the extension number what do we have to do?
<br>I tried with:<br><br>Hook flash version:<br>exten => _XXX,1,Flash() ;do a hook flash (like pressing FUNCTION in meridian phone)<br>exten => _XXX,2,SendDTMF(*70w${EXTEN},250) ;sends the code for transfer plus the extension
<br>exten => _XXX,3,Hangup()<br>In this version I can transfer the call using the same channel (zap/1) but didn't find a way for voicemail if the call is unanswered or is busy.<br>Also if its unanswered the call is returned to the extension were asterisk is.
<br><br>Dial version:<br>exten => _XXX,1,Dial(ZAP/1/${EXTEN})<br>It says the channel is busy.<br>I think that with this version I can have a dialstatus for sending to voicemail<br><br>So, a couple of questions:<br>What is a blind and a supervised transfer? (cannot find it in the norstar manual)
<br>Do you have and use this topology? if so, how do you do it?<br><br>Thanks for the help!!!!!!<br>(I'm a linux sysadmin and never before worked with telephones system)<br><br>-- <br>Gustavo Berman<br>Sysadmin<br>Depto. Informatica
