Nortel digital Meridian phones are like $400/each. At least that was the price of the phones at a hotel I did a job for recently.
When you go to SIP, you may save on the capital costs for the phones, but other costs will increase. These are related to: 1.) increased support requirements for supporting VoIP 2.) additional licensing may be required from your vendor to support SIP or IP media 3.) increased costs associated with mitigating potential damages since your voice services are now subject to the same outages as your network 4.) increased training costs for staff to become proficient in VoIP 5.) increased costs associated with monitoring QoS 6.) increased costs associated with reconfiguring your network for VoIP and QoS - many times new switches may have to be purchased in addition to SBC's etc 7.) additional costs associated with rewiring physical space to accommodate additional Ethernet ports required for phones Sometimes, if you already have digital - it may not be worth switching to SIP even if you save a ton on the handsets. Whenever we switch over a hotel to VoIP, we always run into these extra 'hidden' costs. If you want to do digital with asterisk, I think you'll need a T1/E1 multiplexer that supports digital phones. -------------------------------------------------- Salvatore Giudice [EMAIL PROTECTED] VoIP Security Training, LLC http://VoIPSecurityTraining.com 848 N.
