[asterisk-users] Deployment for less than 10 phones

[Erick Perez]

Im doing some research about how to deploy asterisk in small offices.
So far I have seen the soekris implementation with astlinux and it
sounds good. Please share your comments/ideas for the following
configuration:
Note: Pure PBX only, no routing/firewall functions needed.

Small Office #1
Up to 10 analog phones (FXS)
Up to 3 or 4 PSTN lines (FXO)
Asterisk providing standard pbx features and voicemail.(no call center stuff)
Codec is G711

Small Office #2
Up to 10 Voip Phones (sip) with g711
Up to 3 or 4 incoming SIP lines via Ethernet from the VOIP provider
Asterisk providing standard pbx features and voicemail.
No PSTN connectivity (or maybe just one emergency port???)

The idea to use G711 is to minimize transcoding and to maintain the
costs to a bare minimum. Either using a standard PC or a soekris board
(Epygi Quadro is too expensive and I dont need the routing functions).

Usually is accepted that using G711 on each leg, it needs 30MHZ per
voice channel so a 300MHZ computer will give me the 10 calls I need
while keeping the CPU transcoding to a minimum.

Soekris boards/case cannot fit a TDM400 card unless that has changed
recently, Any ideas if sangoma cards fit?

Also, the net4801-60 soekris board has a 266MHZ cpu so i will only get
about 8 calls. However I need some light here....8 calls FXS to ZAP?
SIP to SIP?

Suggestions for small form factor cases are welcomed.

Thanks for all your comments.

Thanks for our comments.
