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)
• Webex Connect
• Webex Calling
• Webex Integration with the following scopes:

meeting:preferences_write, meeting:preferences_read, spark:people_read

• Service App with the following scopes:

spark:organizations_read, spark:people_read, spark:people_write, spark-admin:licenses_read, spark-admin:people_read, spark-admin:people_write, spark-admin:xsi
