Clear message

In the office, we have a VoipAdapter to connect regular phones.

Server stuff

We're right now using a vserver inside metis.koumbit.net to host the test service. We're considering a dedicated server.

FXO

For the server, we're considering a FXO (to answer and make calls) device for various reasons:

  1. it provides a good timing interface for Asterisk's conferences, interface which works in Xen (provided you give it access), whereas ztdummy doesn't, apparently
  2. connected to a landline, it provides *very* cheap outgoing local calls, provided we have the necessary volume ((20$/mois ∕ 30jours) ∕ 24h/jour) ∕ 60min/h = 0,00046$/min, if used continuously, that is 0,04¢/min. The volume at which this will be necessary is 20$/(0,011$/min) = 1818 min (to hour ≈ 30,30303 h)

Actual prices/providers:

Ebay doesn't have very interesting used material...

FXS

A FXS is useful if you want to hookup regular phones to your asterisk server and use them to make VoIP calls. FXS devices are typically more expensive because they need to generate ring signals and tones.

Actual prices/providers:

Office phones

We're not looking at real VoIP phone yet for price concerns.

Situation is quickly becoming out of hand. People expect the right person to answer and we have to run around the office with the wireless phones to give it to the right person.

Software requirements

Hardware requirements

Wiring phones and workstations is closely related so we must keep the following in consideration:

Basic requirements

* Power over ethernet to reduce wire clutter

  • a cat 5e cable should be wired for every desk for the phone, and workstations should be connected in that phone
  • every outlet should be tested and labeled at the time of installation
  • two-sided velcro (ou des "attaches à pain") should be used to tight the cables together (not "tire-wraps") because velcro can be reused :)

  • a map of the wiring should be done and maintained
Extra
* on both ends of the cable, we should use ports that are reusable and do not require a tool to setup. they a more expensive, but it's worth it, if we move we can remove them and reuse them, I know that 3M makes them.
  • the patch panel should be bought with the ports to make sure they fit
  • patch cords should be "certified"
We do not need
* wires in the walls? (so outlets are not required)

Évaluation de prix préliminaire

http://www.voip-info.org/wiki/view/VOIP+Phones

les prix varient autour de 80-150$ (au pif) sauf chez cisco qui coute comme toujours plus cher.

Guide: http://www.voiplink.com/Power_Over_Ethernet_Buying_Guide_s/329.htm

Donc, 10 téléphones (disons 1000+$), une switch PoE 12 ports (~500$), 10 casques d'écoute (?? 10x50$ ??) ... total: 2000$ ?

hardware acheté

2 ../SPA942 ont déjà été achetés et testés au bureau. Un avec un power supply, l'autre avec un adapteur POE.

Ensuite, j'ai commandé 8 téléphones supplémentaires ainsi qu'une switch POE Netgear: 31431.

Roadmap

We need to build a roadmap on how we will accomplish this, and a timeline, with estimates on the hours required and the delays involved.
