Re: [Asterisk-Users] Soekris and Asterisk
Hi Kristan, The interrupt load is what I am most worried about. At most it would be two spans. Echo cancellation is not required as 80% or more would be fax traffic, the rest IVR and voicemail. I am aware of AstLinux but unfortunately for this particular application the Soekris OS is gonna be FreeBSD as the Soekris is primarily a router with the PRI piggybacking. As far as I can tell, I don't need asterisk installed, just zaptel and libpri. I guess I'll find out. The major reason for this is that I can't physically stick the PRI card in my * server (don't ask!) so this is one of the alternatives I have dreamed up, along with setting up the Soekris with the PRI and IAX2 trunking to the * box but I think TDMoE would be much more efficient. At the end of the day I might just have to get a bigger * server to get the card in, but doing it this way would be an interesting hack and also allows some sort of scripted failover. Eg, if the Soekris sees that a * server has died it can stop the zaptel service, swap in different config files pointing to a mac address in a backup * server and away we go :) Craig - Original Message - From: Kristian Kielhofner [EMAIL PROTECTED] To: Asterisk Users Mailing List - Non-Commercial Discussion asterisk-users@lists.digium.com Sent: Tuesday, October 11, 2005 6:35 PM Subject: Re: [Asterisk-Users] Soekris and Asterisk Craig Guy wrote: Has anyone on the list used a Soekris engineering PC as a TDM - Ethernet bridge?
