[asterisk-users] Asterisk cluster and call pickup
I'm planning to migrate 500+ extensions from a legacy PBX to Asterisk. Some will be SIP, some will be DAHDI FXS. I want to deploy a load-balancing cluster using DUNDi with regcontext so all servers will know where to find all extensions. DAHDI extensions will have their dedicated server, SIP extensions will be spread out on 3 different servers. Now I'm wondering how would call pickup work on that scenario. Is it possible (maybe with distributed devstates) to pickup a ringing channel on a different server? Or is there a different way to load balance while keeping call pickup functionality intact? Any input on this is very welcome. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

[asterisk-users] Asterisk Cluster Scenario
Hello folks, my company has experience in setting up single asterisk setup, but recently one of our customers asked us to set up an asterisk cluster, that must be High Availability and Load Balanced. So I wrote here to have some hint or advice about the configuration we thought. First of all I'll explain you the scenario: The asterisk cluster must serve as Call Center "Hub-and-Spoke". There are lots of little call-centers (~15 ops), phisically separated, that must appears as a single "Big Virtual Call-Center". The call-center is inbound and outbound. Initially the "Virtual Call-Center" will be composed of 15 small call-centers (= ~230 ops), but the prevision is to grow to ~800 ops. Asterisk must work as B2BUA, because the customer does not want the call-centers contact directly the upstream SIP providers. Asterisk server must also record the call and, maybe, do some transcoding. The single asterisks instances talk each-other with DUNDi/IAX2 to pass the calls from an op to another op registered on another server. We'll use a mysql database (NDB cluster) to avoid to have multiple sip.conf files with the registration informations (asterisk-rt). We must, in any case, use asterisk, because the whole call-center has to be integrated with a 3rd part software for predictive calling ad power dialing which has been developed for asterisk. The SIP servers are behind NAT, because the customer want to use only one public IP address; every asterisk server will have a different RTP port range to avoid rtp conflicts. And, for now, the LB part works manually registering the ops on different asterisk servers. But now we have to achieve the HA part of the setup. We started considering a SIP hardware load balancer, like Radware or Brocade, but neither a single nor a couple of this equipments (HA, remember?) do not fit in the customer budget. So, we started thinking about use OpenSIPS (formerly OpenSER) as a SIP load-balancer. (the customer has server hardware that could be used for this, and we will use VRRP for redundancy). In the OpenSIPS features we read "load balancing with failover", but we could not find any useful and complete configuration example. Is OpenSIPS able to know if an asterisk server is UP or DOWN, or must we use a 3rd part tool, like mon? Anyone has experience in use OpenSIPS as SIP load balancer (not to work as "real" SIP proxy)? Any hint/advice for this part, or for the global setup? Thanks in advance for the help! Stefano PS: sorry for my weak english PS2: sorry for cross posting but, if the general setup is more asterisk related, the OpenSIPS part is, obviously, OpenSIP specific. -- Stefano Sasso http://stefano.dscnet.org/ -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Without knowing exactly what you are trying to do beside having at least 500 outbound calls, that would be impossible to say.

Your up front cost is going to be a little higher with TDM -> SIP devices, but your management will be a lot easier. AudioCodes also has equipment that can support a DS3 connection, or multiple T1s directly to SIP. For example, If you are getting 22 T1s then get two AudioCodes Mediant 2000s with 16 spans (maxed out) or two Mediant 3000s with 21 spans. If you are getting a DS3, get a Mediant 3000. The M3000 supports up to 84 T1s or three DS3 or one OC3. Then leave call management up to Asterisk. Of course, have redundancy everywhere you can. -Jonathan -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

This is correct, astdb isn't stored in a database and essentially your scenario with astdb file being shared won't work or will be highly unreliable.

The number of Asterisk boxes depends on the application. If you get your calls via PRI's I suggest exploring 2 MaxTNT's each with DS3/GbE interfaces and a lot of redundancy.

Re: [Asterisk-Users] Asterisk Cluster
Inbound calls? Outbound calls? Zap channels (TDM) ? SIP channels? IAX channels? There's a good number of questions that need to be answered before one can get to an answer on your original question.

Hello, I'm going to need to take up to 10,000 simultaneous calls on a single number. I'm going to need lots of * boxes to do it.
