Question for Asterisk 13.20.0.rc2 to exist on GCP what does Asterisk/PJSip need the Kernel to have to support VoIP? There is installed TDM’s in this environment. How do I get PJSIP to treat the assigned IP addresses a secured local network?
@jcolp there are restrictions on telecommunications connecting directly to a PSTN but cloudy about SIP Trunking. The issue remains the instability of the duration hearing the caller because of this. I am presently testing the same scenario in Microsoft Azure, AWS, Digital Ocean and Alibaba [which is going to be interesting because it is located in China] update to follow.
If you want negligible degradation, you should be aiming at scheduling latencies of under 2ms. 20ms is probably going to be tolerable. 100ms is way too high.
