[Asterisk-Users] Can this box handle 8 T1s (PSTN) with Asterisk?
Hi all, I am handed a project to setup *. The requirement is that it can handle 8 T1s. Half of the calls coming into the system will be routed to SIP extensions (with transcoding). The machine we have in our disposal is a new dual Xeon 3.2gHz server with 2g of ram and an dual 1000mb nic. Voice will be coming in from the PSTN (through 2 quad digium cards) in g711ulaw, and most of the time will be doing IVR with dtmf detection. Half of the calls will eventurally got routed to sip extensions and the requirement calls for keeping the bandwidth to a minimum; so we force all the sip extensions to only use g729. Is this machine capable of meeting the requirement? Thnx. -------------- next part -------------- An HTML attachment was scrubbed...

What will my CPU utilization like? Will it be like 50% or more? ________________________________ From: asterisk-users-bounces@lists.digium.com on behalf of Andrew Latham Sent: Wed 3/22/2006 2:11 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Can this box handle 8 T1s (PSTN) with Asterisk? yes On 3/22/06, Wai Wu <wwu@calltrol.com> wrote:> > Hi all, > > I am handed a project to setup *.

on half of the inbound (less than 48) to sip phones with g729, load will be high, but that is a lot of licenses to buy so I will suspect that you will end up using ulaw/alaw.

I don't know what the MIPS requirement is for trans-coding g729; but only 4 Ts worth need to be trans-coded for my installation. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Andres Sent: Wednesday, March 22, 2006 3:56 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Can this box handle 8 T1s (PSTN) with Asterisk?

We will do some test and if the load is too high, we will go with extenal trans-coders boxes. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Andrew Latham Sent: Wednesday, March 22, 2006 4:04 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Can this box handle 8 T1s (PSTN) with Asterisk? on half of the inbound (less than 48) to sip phones with g729, load will be high, but that is a lot of licenses to buy so I will suspect that you will end up using ulaw/alaw.
