You can use the digital phones with Asterisk. Just that you need a Citel Portico external box to convert the proprietary (ie. Digital) non IP protocol that cannot work on TCP/IP networks to standard IP SIP protocol that can. At about $120 per port the advantages and "potential" issues may or not make it feasable. If there is already a significant investment in high end digital phones that can cost many hundreds of dollars each and you want to continue to use the existing wiring it is probably worth considering IMHO.

It is *not* that the digital phones do not need a card. It is that there is no card on the market that will work with them. > Also, how it will use ethernet switches! It will not use ethernet switches. > It does not work with IP Packets. No, it does not, and it will probably never work. To make it even clearer: Bilal -- You cannot use your digital phones with Asterisk. Period. Either: 1 - use a matching digital switch (Nortel Meridian or Norstar, etc.) 2 - sell the phones and replace them with proper IP phones that you can use over an IP network. If you are concerned about availability in the event of a power failure: Purchase an Uninterruptible Power Supply of the appropriate size, Power over Ethernet injectors, and configure your system such that it will stay up during a power outage. -Stephen- _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
