How Many Calls Per Asterisk Server

In the installation guide it states "In general, you can expect to get 25 outbound agents dialing 4:1 ratio or 50 inbound agents with 100
concurrent lines on a dedicated Telephony server using the standard hardware specification". That is 100 calls at once. If the number of
agents is reduced but ratio increased, would it be the same expectation? For example 10 outbound agents at 10:1? And what would indicate that the number of calls at once was more than the hardware could handle? Dropped calls? Dropped recordings? How would I know if I overloaded the asterisk server?

It really depends on the hardware you are using, but the issues that happen with an overloaded dialer are frequent Asterisk crashes, Asterisk becoming unresponsive, audio choppiness, delays in commands being executed and possible recording issues(missing/late-starting/multi-call-in-single-recording)

We have noticed with Asterisk 13 that we can get more reliable capacity out of the same hardware when using Asterisk 13 compared to earlier branches.

Do you now recommend upgrading to Asterisk 13 for vicibox 7.04 and vicibox 8.0.1, or keep the installed version until vicibox has 13 built in?

[mflorell]

I haven't tested Asterisk 13 on vicibox 7, but I know it works great on vicibox 8. We have upgraded dozens of clients to use Asterisk 13 and the most recent svn/trunk revision of VICIdial and it works great.
