Hi everyone,
I'm currently working on migrating our telephony system from Cisco CUCM to Webex Calling. Our current setup relies heavily on CUCM's ability to send an ECCP (External Call Control Protocol) request to our system, wait for a response, and then continue call routing based on that response.
As I understand it, Webex Calling doesn’t support ECCP directly. So I’ve been looking for a similar mechanism that could allow our system to influence or control call routing in a comparable way.
So far, I’ve considered a couple of alternatives:
Using Webhooks + Webex Calling APIs: Our system would listen for Webex Calling events (like an incoming call), run its own logic (which mimics the ECCP decision-making), and then use the Webex Calling API to take appropriate actions (e.g., redirect the call, reject it, etc.).
System-Initiated Calls: Instead of waiting for Webex to notify us, our system would initiate outbound calls and execute the ECCP-like logic before dialing. This would give us full control, but might require a shift in how we handle call flows.
My questions:
Is there a native or recommended way to implement ECCP-like behavior in Webex Calling?
If not, what’s the most viable workaround for systems that need to intercept and approve/reject calls based on external logic?
Any advice or pointers would be greatly appreciated. I’m still trying to fully understand Webex Calling’s capabilities, so apologies if I’ve misunderstood any part of the architecture.
Thanks in advance!
