I appreciate your responses. However, I feel like I'm not explaining myself very well.
When you say the system is highly scalable, are there any numbers / specs that show just how scalable it is? Does the 250 number for concurrent calls not include RTP streams? Basically, we need to understand the numbers. Does any documentation exist for this?

Not necessarily. The system is highly scalable. One bridge makes a single point of failure. HA is a master/distributed but not a master/slave model. Even so, it is more preferable (to me anyway) to make any site or group an "island" when it comes to communications. I find it easier to troubleshoot, plan and operate. People are always trying to do things with HA and really assume how it all works. Good luck, sounds like a lot of fun. ============================ Tony Graziano, Manager Telephone: 434.984.8430 Fax: 434.984.8431 Email: [email protected] LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 Fax: 434.984.8427 Helpdesk Contract Customers: http://www.myitdepartment.net/gethelp/ ----- Original Message ----- From: Ken Fulmer <[email protected]> To: 'Tony Graziano' <[email protected]> Cc: [email protected] <[email protected]> Sent: Thu Mar 04 18:13:25 2010 Subject: RE: [sipx-users] 250 Concurrent Calls? I might be misunderstanding the capabilities of the system. Can't we use two servers in HA (primary and secondary) with a third as a sipXbridge? I didn't realize each server had to run the proxy services. However, the third server wouldn't have any phones attached - it would be used for PSTN call routing. Is this a configuration that makes a cluster more scalable?

Understand. I'm not sure how "standalone" it will be. For example, right now ANY server in HA must run a proxy. Voicemail is another that is not standalone. Sipxbridge has nothing to do with internal calls, just itsp connections. Once you get a handle on the requirements and they make sense on how they were arrived at, post back. ============================ Tony Graziano, Manager Telephone: 434.984.8430 Fax: 434.984.8431 Email: [email protected] LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 Fax: 434.984.8427 Helpdesk Contract Customers: http://www.myitdepartment.net/gethelp/ ----- Original Message ----- From: Ken Fulmer <[email protected]> To: 'Tony Graziano' <[email protected]> Cc: [email protected] <[email protected]> Sent: Thu Mar 04 17:43:29 2010 Subject: RE: [sipx-users] 250 Concurrent Calls? I'm trying to understand how the 250 number was generated. We'd want to use a dedicated server for the sipXbridge.

Does anyone know what server specs are required to get this number of calls through the server comfortably?

It really depends on the roles being used for the server. sipxbridge is used for ITSP trunking. If you are also going to have remote users you need to ask a similar question about media relay I think. Voicemail/AA/CDR/ACD roles also play a role, as does configuration, and whether or not this is part of a HA system or not. bandwidth might also play a part here too. If you can better describe what you expect your environment or use case, you can expect better guidance. _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
