Re: [asterisk-users] Maximum number of users
Generally its best to keep to a maximum of 2 PCI cards in a server as they each generate a lot of interrupts. The IRQ distribution should be checked on a multi-processor system. I typically have 3 Sangoma cards in low end Xeon servers and there aren't any problems. Recently, I needed to patch irqbalance to evaluate the numa node values because some somewhat older versions of CentOS (6.3, 6.4 initially) do not set certain links inside sysfs. If there is some interest, I could publish my small patch. jg -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Maximum number of users
You need to decide which codecs you are going to allow to be used on the SIP side. As you are connecting to E1 then the standard codec would be g711 alaw or ulaw. You could force the SIP side to use the same codec but it uses about 100Kbps of bandwidth so quite a bit higher than other codecs and some customers may prefer to use a higher compression codec so they dont have to have a faster internet connection. If you start allowing other codecs then asterisk will need to perform codec translation which consumes CPU. You will be limited by the E1 cards you can fit into asterisk. Generally its best to keep to a maximum of 2 PCI cards in a server as they each generate a lot of interrupts. A couple of Sangoma A116 will give you 32 E1 circuits which can handle 960 calls. That may well be pushing the server to its limits of what it can do even if it is just handling basic calls. So you will want 3 of these systems and preferably four as you will want some redundancy. You would want something like opensips at the front end on a couple of redundant servers. You can use the load balancing module in opensips to spread the calls evenly between the available asterisk servers. You should also have a think about whether you wish to use asterisk at all. Opensips will do the load balancing that you need and can perform the billing actions aswell. If all asterisk is doing is performing sip to E1 conversion there may be hardware solutions which will be more cost effective and require less maintenance.

Dialplan complexity, new call rate, features enabled, and transcoding all play a factor in these numbers. To give you an example I have a Dell R710 with two quad core E5520 processors running Asterisk 1.8 and FreePBX 2.11. I have around 1,000 SIP device registrations, 50-80 concurrent calls for the majority of the day, and a total of 8-10k calls processed per day. A few times a week I will see the last minute load at 20 and the 5 min load at 7. This seem to happen when there are a high volume of new calls as the FreePBX dialplan is complex.

Re: [asterisk-users] Maximum number of users
Thats fine for calculating how many users a particular speed network
connection can cope with. 640 concurrent calls on a 100Mbps connection
is doable on a decent machine as long as you are not doing much codec
translation.
Once you get to the point where you start having hundreds of users then
you really need to think about redundancy. OpenSIPS is a good way
forward as it is very light weight and can easily handle tens of
thousands of registered phones. As calls come in then it can forward
them directly or if additional services are required such as possibly
voicemail it can pass them onto one or more asterisk servers in a load
balancing arrangement. Using a couple of database servers replicating to
each other and a virtual IP address (or DNS SRV if the clients properly
support it) will give you redundancy and allow you to add more server to
expand the capacity.

Hi Bilal,
Assuming you have the latest hardware, sufficient memory, cpu, etc...
The key to determine the maximum number of users comes down to the
office type, RTP path, network interface, and primary codec used.
First we need to determine the over-subscription rate, how many people
will be using the phones at any given time.
For a call center, the ratio is 1:1.
For a normal office, the industry standard is 4:1.
{This ratio is also used to determine the number of PSTN channels you
will need too}
Will the PSTN connections be Digium card(s) in your server or external
gateway(s)?
Assuming Diguim card(s), the RTP will be going through your server.
Determine the network interface. 10/100/1000baseT
Then we need to consider the largest codec used, and divide the
available bandwidth by the typical packet size.
µ-law/A-law is roughly 80 kbps, so we can support 128/1280/13107 audio
streams.
Divide that by 2 (just to be safe) and allow RTP in both directions.
64/640/6553
Now multiple the result by the over-subscription ratio. 4:1 =
256/2560/26212
So we see that the maximum number of users is 2560 for a normal office
when there is a 100baseT NIC in your Asterisk server.
You would also need to have 640 channels (28 T1 PRI's) connecting to
the PSTN.
/Using SIP trunks to connect to the PSTN through the same 100baseT NIC
will reduce the maximum number of users you can support./
The real challenge is not supporting thousands of users (IP Phones),
it's connecting a sufficient number of PSTN connections to support
those users.
Sincerely,
Brian LaVallee

Re: [asterisk-users] Maximum number of users
We have a machine with a quad core 'Intel(R) Xeon(R) CPU E5-1410 0 @ 2.80GHz' running asterisk 11.2-cert with ingress and egress all sip. Fastagi running as a daemon (written in perl) performing cdr updates at call start, answer and call end together with a query when a call comes in to get information on what to do with it. Local Mysql 5.5 database. With all this we easily handled 450 simultaneous calls with many of them also performing call recording. I think we typically had 60% idle on each processor so the box could be pushed a lot more. On 18/12/13 15:46, Tech Support wrote: How did the system behave with 244 calls?

We had about 120-150 users in a conference, that seemed to be okay, heard a complaint about a periodic sputter in audio, but nothing to serious. Issues came once the call was done, ~150 users all hanging up at once. SQL was VERY upset with that, causing * to choke. Though I think it was how we handled the deployment to get it up quickly, and may have been able to prevent this, if tested better.

Re: [asterisk-users] Maximum number of users
How did the system behave with 244 calls? I've been able to make 1,024 concurrent faxes (which tend to use more resources than audio calls) in the lab. The problem I had was after the faxes were transmitted, things couldn't keep up and kept dumping core. Two things were going on, (1) the CDR was written to MySQL and (2) a FastAGI script (I use the AGISpeedy PERL package) to write a log entry also to MySQL. I tried switching the CDR's to sqlite and that seemed able to keep up, except that its concurrency issues were a problem. If MySQL is the problem, I could probably optimize it better, but it doesn't explain the Asterisk core dumps. It might be related to the number of FastAGI scripts running, I'm not sure at this point.

Re: [asterisk-users] Maximum number of users
You can have tens of thousands of phones as long as no one makes or receives any calls J. The better question to ask is how many concurrent calls have people been able to make. The quick answer is it depends on many things.
