Actually its not very far off topic. When starting a new project, say 1000+ extensions, the decision is complex. If you need 1000+ IP phones you need to verify your supply chain and calculate cost of installation. If you have manually touch or even scan the phones then things get complex real quick. For example some suppliers will print additional information on each box of phones to make deployment easier. If you get your boxes of phones with user or cubicle names printed in relation to the MAC and also have the list for configuration then you look like a super hero... Price is not the deciding point on real projects, its the supporting infrastructure. We are also working to get some ATAs like the Audiocodes to work from the res_phoneprov. I have hacked together a TFTP proxy with the help of some existing projects. You can read more here http://etel.wiki.oreilly.com/wiki/index.php/Dynamic_Phone_Provisioning_with_res_phoneprov_and_TFTP Some notes on IP hardphones to look for... * Button Labels, When dealing with languages other than English you need to verify that the phones are available with per language button labels or no labels and on screen soft buttons in the language you need. * Configuration of VLAN on the phone. Can it be done automatic or is it a manual setting. Does the phone support vlan tagging. * Firmware updates: Are they free, fast and stable? * POE standards. Does the phone communicate its required power to the switch correctly (not all switches or phones like each other.). Example: Polycom 330 and Cisco 2960 = all ports think they need 15.4 watts and may over saturate the switch power supply causing random ports to have POE turn off. Polycom 331 and Cisco 2960 = All ports communicate with the the phone and set wattage to ~4 watts +- cable length * Sidecars for the phones. Can you dynamically add side cars to the phones. Lucky that today you can just order snom Visions and do some hacking to fix this issue. * Directory XML App. When you exceed the internal directory size, can you create an XML app to allow the searching of a corporate directory from the phones screen. (Hint: res_phoneprov + xml app + dynamic alphabetic pages) * Power Adapter: Many providers have order numbers with and without power adapters. In every installation you will need power adapters for testing, verifying and for edge devices. * Headsets: Customers request computability with headsets. There are Linksys phones shipping today with bluetooth. My snom 870 has two types of headset plugs on the back. * Handset cord length: Some phones have long handset cords, others not so much. * Handset weight, does it feel too light and weak * Mounting, Are there wall mounting and multiple position desk mounting options * Wireless/dect/cordless = Is it a dangerous environment? I have purchased simple analog phones at walmart for projects where the cordless phones are damaged too often. ~~~ Andrew "lathama" Latham [email protected] ~~~ -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
