I’ve been asked by a client to look at Asterisk in order to build an automated survey system. This survey system has to be enhanced such that the besides making choices with the keypad the surveyee can also leave audio comments which must be recorded.
There are a number of areas that I’m not quite sure if Asterisk can handle that I would like to just clarify.
The automated system might need to send a few DTMF tones to get through to various extensions and I know some of the surveyees will be on SIP phones. How well does Asterisk do in sending DTMF to SIP?
Following on from 1, we’re considering putting the Asterisk server in a data center and calling via SIP out to the PSTN via a company like Vonage. Again, will sending DTMF tones be an issue? Anyone know of any VoIP companies that handle DTMF nicely? How nicely does Asterisk handle SIP calls generally?
I hope to be controlling the logic of the system via the AGI. From my brief reading of the Asterisk docs it seems that AGI is primarily for incoming calls. Is AGI easily usable for outgoing calls?
Will it be too much of a problem that Asterisk does not connect the suerveyee to an extension? In this system the call doesn’t leave the Asterisk system. Will this be a problem?
Thanks in advance for your help,
