Hi,<br><br>I have some cases that I need to use Asterisk as an IVR/VoiceMail only. It will be connected to legacy pbx using a serial port (R2-232) to exchange integrations and/or messages to allow pbx to send to terminal extensions 'message indications' (a led on in KS).
<br><br>I know Asterisk can do it alone and better, but in some cases isn't possible to change the pbx structure and this protocol via rs-232 is widely used for some big pbx systems.<br><br>Any direction? Is there already a solution for this? Or I need to do a custom development?
<br><br>Thanks in advance!<br><br>Paulo<br>
