All of our users' login to a Remote Desktop Server and use an Access / VBA application on that server. We want them to be able to dial contacts on that database (via 3CX) at the press of a button. However, the 3CX server will be on a different site.
I understand that the 3CX API used to initiate the call needs to sit on the 3CX server, so we will need to establish a way to send a signal/message to that API (on a different server) in order to initiate the call.
I have a pretty good knowledge of VBA, Javascript and am OK with c#/.Net - but before I embark on this project I want to check a couple of things (and hopefully get a little guidance):
1. Has anyone already done this, who would be willing/able to supply a solution that gets us close
2. If not, I could really do with some pointers (that would speed things up), as to the process/methodology required. For example:
- Write a DLL (via C#) and reference it into the VBA application
- Write some VBA to communicate with the DLL and pass the necessary variables to make the call
- Write a small service (via C#) that sits on the 3CX server and can initiate a call
- Make sure the Firewalls are set-up to allow communication between the two servers
- Have the local DLL open up a communications channel with the 3CX server
- Have the local DLL communicate with the small application and send the relevant variables to make the call
- Obtain call results (I could possibly use the REST API for this to make life easier)
The above is pretty much guess-work, so any guidance, code snippets or help in general - would be massively appreciated.
Thank you.
