I have many years experience of CTI on the likes of Avaya, Mitel, Cisco etc, but I’m totally new to Asterisk.
I’m looking for advice on where to start with a CTI requirement.
I have a core requirement to programmatically send DTMF digits down a connected, external call (connected to a handset) from a server process when it recieves a trigger/event. The phone system is a Digium (it’s pretty new, but I don’t have the version number to hand). Preferably our server process would be written in .net, but we can use C++ or Java if we have to.The reason for this requirement is to comminicate (occassionally) with an existing line-side process listening for DTMF on the trunk.
Having read some of the available Asterisk documentation I think our best option might be to make use of the SendDTMF command of the Asterisk Manager Interface. It looks like the AMI already has a .net wrapper (AMIConnector) so we don’t have to use the raw TCP/IP stream.
So …
- Is the AMI Connector the best option for programmatically sending DTMF down a connected call from a third-party (not first-party) CTI application?
- Will this work on a Digium system, or might the interface be locked down etc?
- Assuming AMI is the best solution option, are there any costs (e.g. license costs) or restrictions associated with using AMI or AMIConnector in a commercial product?
- Again, assuming AMI is the best solution, can anyone recommend the best developer’s guide to programming and configuring AMI?
Many thanks.
