Hi guys,<br><br>I know that this could be considered a bit off the
topic, I've just posted this topic at VoIPSEC mailing list but I just thought this could be very interesting for Asterisk community members so I'm posting it here too.<br><br>So the point is for traditional telephony we expect service
availability of 99,999% and what about VoIP providers around the world
what is currently available?<br><br>I know that some operators are not
owners of the infrastructure so this becomes even harder to warranty
the high level requirements that telephony demands.
<br><br>The best info and explanation I've found until now is: from bandwidth at <a href="http://www.bandwidth.com/pdf/voip/bandwidth_voip_sla_062105.pdf" target="_blank">http://www.bandwidth.com/pdf/voip/bandwidth_voip_sla_062105.pdf
</a><br><br>It would be interesting to discuss the recommend values needed and available at SLA agreements:<br><br>Max Latency<br>Max Jitter<br>Max Packet Lost<br><br>Mean Time Between Failures<br>Mean Time To Repair<br>
<br>
Mean Opinion Score at least 4 ?<br><br>Service
Availability, this point as you probably are aware is very important,
what I just notice a few time a go is that the difference between 99,9%
and 99,999% is big!<br><br>99,9% -> Max time for Outage during one month is 43,2 minutes , considering 30 days per month
<br>99,999% -> Max time for Outage during one month is 0,432 minutes<br><br>If any of you around the world is aware of this values for VoIP SLAs I would be thankful to exchange and discuss this info.<br><br>Thanks in advance.
