[Freeswitch-users] FS beats Aculab Prosody S on subjective test on lay users for conference quality

[David Knell]

Hi Fernando,

Greetings from Rio..!

It'd be interesting to understand more about these results - roughly
speaking, two conferencing systems using the same codecs, etc., ought to
perform pretty much identically, particularly with just a few callers.

I'd be interested to see a network packet dump of a conference on each
of the machines, if you're able to make one available.

Cheers --

Dave

> All users preferred FS. Some users were almost enthusiastic after

> FS. The average report told 50% more satisfaction on FS. Questions on
> report were simple ones, with results from 1(worse) to 5(best) :
> 1-Overall opinion(1-crap; 5-awesome);
> 2-Delay (1-more delay, 5-no delay at all);
> 3-Audio quality (1-noisy, choppy, etc; 5-cristal clear);

> Machines used:
> Prosody S: Windows Vista Business, Intel Core 2 Duo E7400 @ 2.8
> GHz, 4Gb de RAM
> FreeSwitch: CentOS 5.4, Intel(R) Pentium(R) 4 CPU 2.40GHz, 1Gb RAM
