+1 - if reliability/quality are important (especially if you're looking for 24 (well, 23) channels) - PRI is the way to go. We have some call limit features in place on our Patton PRI gateways - if we have over xx channels in use, we can force outbound calls to be sent via a sip trunk (registered on the PRI gateway) to keep a few channels dedicated to inbound calling (this should only be an issue if you're worried about ever having more than 23 calls simultaneous calls the PRI) - basically, the sip trunks becomes your overflow for any outbound calls.

We would prefer not to deal with trunk or internet quality if we don't have to.

We use Appia for all deployments. The load you noted here will be fine. they offer trunks with or without T1's. Your biggest question is what to use for your internet connection. If they will have 24 simultaneous calls your looking at about 2048 KB if using G.711U (86KB with payload plus overhead). Which means you will need to move to G.729 to fit your max call bandwidth inside a T1. -M >>> Tommy Laino <[email protected]<mailto:[email protected]>> 07/03/12 12:21 >>> PM >>> I am recommending a SipX to a customer. They are going to be converting from PRI to SIP trunking. They want to have 24 trunks available for calls. I am assuming that the internal SipX bridge is not going to be sufficient for the amount of calls that they are looking to handle. I am looking for recommendations from the forum for the best way to handle all 24 SIP trunks including best hardware and SIP providers for this deployment(I have used VoIP.ms and DIDLogic in the past). Any help is greatly appreciated. -- Tommy Laino Dome Technologies _______________________________________________ sipx-users mailing list [email protected]<mailto:[email protected]> List Archive: http://list.sipfoundry.org/archive/sipx-users/ _______________________________________________ sipx-users mailing list [email protected]<mailto:[email protected]> List Archive: http://list.sipfoundry.org/archive/sipx-users/ LAN/Telephony/Security and Control Systems Helpdesk: Telephone: 434.984.8426 sip: [email protected]<mailto:[email protected]> Helpdesk Customers: http://myhelp.myitdepartment.net Blog: http://blog.myitdepartment.net ________________________________ This message and any files transmitted with it are intended only for the individual(s) or entity named.
