Actually, out of curiosity, and since I want to get rid of Asterisk and replace it with something (anything, so help me, anything at all) else. FreeSWITCH is popular at the moment; the only other convincing option I have run across is yate. So, dear lazyweb, can you tell me: Have you actually used FreeSWITCH or YATE in a small SIP-only environment? Did it work well, reliably and with minimal maintenance? Did it work effectively as an answering machine for home? (That is, play a message, record the caller message, notify you, with nothing much more fancy than that available?)

I put up my HP PSC 2410 (multi-function, including a scaner) on eBay and got $5.50 for it (yes, five dollar fifty cents). Someone in Melbourne who put up exactly the same printer at the same time got same price (both of us didn't offer shipping so we didn't compete with each other).

No, but I can advise you how to answer that question for yourself: http://www.sane-project.org/sane-supported-devices.html See also the list of external providers; the HP software is referenced from there, and supports more or less everything they do, but check their HCL to be certain. That is the software behind all the Linux scanning support, so what it supports is what will work with Linux. > New or second-hand is OK.

This is a good idea: Asterisk, and VoIP in general, have a non-trivial number of potential issues that can cause you significant grief if you don't know about them before you start. This, or some other VoIP based solution, is a fairly reasonable strategy though. I would suggest you look into VoIP / Asterisk solution providers in your area.

Re: [SLUG] Ask SLUG - IP Telephony
Hi Ben, I have done a variety of IT projects for a living in my time, including an implementation of a proprietary VoIP system. While I arrived at the project with good IT and Data Network experience and even some insight into Telephony and long distance dedicated links - the main issue I struck was that the gulf between the even Digital Telephony and Data worlds (both internal groups and suppliers). In no way is this a definitive list - but things to watch out for include: Network design, Quality of Service (a big thing in Voice communication) and IP telephony offers new features, sometimes at the cost of reliability of the good old times when you could pick up a phone and expect it to dial and speak! With regard to costing, the equipment is easy to cost, network/telephone budget, the change/project management is usually more difficult. Testing, running parallel systems and redirecting telephone numbers in different jurisdictions isn't a trivial exercise either. Most people now see mobile phones as the back up system - which may need to be costed into the company if not the departments bottom line. I haven't used Asterisk - but it is worth checking out how it fits into a VoIP network, rather than just whether it handles Digital and Analog Phone lines/links.

(perhaps come in or give an intro on what > you can do for us?) the simple steps I did to get voip (not necessarily foss ) into the places I manage 1) played with it a home - get to know your hardware/software/ acronyms 2) I went with a sipuria ata 3000 - if fits between you phone and the exchange no need to change the phone or phone line - you do need an internet service capable of handling voip. Note I have also placed it between a pabx and exchange. sipuria got bought out by linksys now cisco the current module is a spa3102. The really good thing about them is once they are in place if anything goes wrong, just pull the power and the fall back to straight through connections to the pstn - as if the device wasn't there. Now just route all your outgoing calls with a VSP. I would suggest pennytel for one reason, they can make you number (CID) look like your pstn number, my net phone can't so outgoing calls looks like they came from your normal land line. you will probably save most of your cost with the above setup. (depending on the number of lines and simultaneous calls etc etc0 once you happy with this then maybe move forward with voip / ip handset > > Thanks, > Ben > > > -- > SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ > Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html > signature.asc Description: Digital signature -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
