Application that can receive PSTN calls (Webex Connect) with custom IVR, and direct the caller to a Webex PMR (by way of Webex Calling).
This project was developed to provide a method for PSTN callers to join PMRs using a single static DID and a static 7 digit PIN, that can be customized by each user (per PMR).
The PSTN Flow:
- Caller dials a Webex Connect number which triggers a Webex Connect Flow.
- Webex Connect Flow collects DTMF input, and sends an HTTP POST with the caller number and entered digits to our server
- Webex Connect Flow patches the call to Webex Calling Queue (empty)
- Our server monitors the Webex Calling Queue using XSI
- When a call enters the Queue that matches the POST we received from the Webex Connect Flow, we transfer the call to the Webex PMR
The Server:
- Our python server.py is listening for POST requests from Webex Connect
- Our python server.py is monitoring the Webex Calling Queue
- Retrieving/Storing configuration information from/to MongoDB
- Developed on MacOS Ventura (13.2.1) & Ubuntu 22.04
- Developed on Python 3.8.1 & 3.8.3
- Other OS and Python versions may work but have not been tested
- Mongo DB (i.e. Atlas)
