[Asterisk-Users] Are there any digital phones that run on asterisk yet?
Are there any digital phones that run on asterisk yet? I'm talking about non-IP phones here... John

>Asterisk can work with ADSI phones,What I have in mind is a pci card with zap-like-driver that supports digital phones. This eliminates (is compairable to using channel bank) additional delay and a primary echo source when both haves of a conversation are carried on the same pair as found with fxs ports. There are many reasons why this is superior to the channel bank/analog phone route especially when VoIP comes into the picture. This is also superior to an office filled with IP phones and a centralized asterisk switch - although there are times where it is clearly advantageous to use an IP phone, such as distant office phones or if all of your calls are destine to IP. But if you are connecting to a telco, calls that avoid IP are always going to be superior and more reliable (with the current state of things). Anyway, there are many pci/digital phone key system or pbx manufacturers. At some point they will see the inevitability and potential of the Asterisk market and modify zap or make drivers for their equipment. This is a problem for independent developers because if you began to make this type of equipment, you have to potential of instant heavy competition. Maybe it would be a good open hardware project like zappata. Anyway, if you think asterisk is growing fast now, just wait till this happens... Anyway, I need hundreds of these phones. I am using Asterisk as a bridge to several aging PBXs and am expecting to one day run all of my wired phones native in Asterisk. John

These folks have some interesting ideas: http://www.citel.com/products/docs/SIPProdSht_5.19.04.pdf

Voip does cause a delay that necessitates the use of an echo canceler. Another advantage is that most proprietary digital phones have a lot more programmable buttons/leds/whatnot than current voip phones. One problem I see is that there are several different poprietary digital phone interfaces. Peter
