Ok, feature request for progress detection opened as OPENZAP-70. Meanwhile, I humbly offer a basic working environment in Spain (a TDM400 with 1xFXO) if you need it for testing. François. On Wed, 2009-05-20 at 08:08 -0500, Anthony Minessale wrote:
The most difficult one would be the cadence detection. The rest are just based on events from the driver. We have never tried it in Spain so we unfortunately have not had a working environment to test it in. I am sure we could strive to support your requests but it will take time and resources so maybe you can open a feature request on jira http://jira.freeswitch.org and we can try to keep track of your endeavor.

I briefly looked at the code, so I will then answer my own questions from what i understood (and I didn't understand much). Please correct me if I'm wrong (see inline answers).
A new question would then be: Are any of those features planned for the future of OpenZAP?

No.

Yes.

No.

No.

No / No idea / No idea

You're welcome!
