asterisk users - Oct 2017 - Measuring total end-to-end latency

Hi.

Does anyone have some recommendations for measuring total end-to-end latency 
(by which I mean: the time between person A saying something and person B 
hearing it) when there are both SIP and PSTN/analogue/mobile legs in the call 
path?

Examples:

Person A has a SIP phone registered to Asterisk, which has a SIP trunk to a 
connectivity provider, who has connections to PSTN (analogue landline) 
connectivity providers and to mobile network (Vodafone, Orange, etc) 
providers.

Person B might answer the call on an analogue landline telephone.

Person C might answer the call on a mobile phone (perhaps on its home network, 
perhaps roaming on a foreign network).


Is there any way to measure total latency of calls between A and B or A and C?


Thanks in advance for any ideas / suggestions.


Antony.

Hi,

I don't have a direct answer, but I've read several times about
purposely
customized system over the PSTN, echoing incoming incoming audio to produce
metrics
when troubleshooting call quality.

I alse remember a thing called Recqual targeting the same goal.

I hope this helps
