[OpenSIPS-Users] Fwd: Push notifications

[Babil (Golam Sarwar)]

Hi José,
thank you. I have a somewhat similar implementation but on top of OpenSIPS
1.11.

I run a daemon that waits for signals from OpenSIPS for triggering push
notifications. Then the rest of the REST-API call (implementing the APN
functionality) is handled within that separate daemon's thread. OpenSIPS is
blocked for minimum amount of time during the REST call. How do you make your
REST calls from the OpenSIPS script? Can you add an example?

Also, in order to wake up Bob and receive calls, in my system I have basically
made Alice to retry a given number of times. Since in my scenario, I control
my SIP clients, it is feasible. But this may not apply to your case.
