What is a VoIP Gateway

Hi

A VoIP Gateway allows you to place off network calls, in other words calls can now be routed from your LAN into a PABX or POTS network. The device has a number of ports, most notably LAN port/s and FXO and FXS ports to connect to telephone instruments or PABX/POTS line/s.

Next you need to setup a dial plan on your VoIP server that will route calls off the LAN under certain conditions, such as if a user precedes a number to be dailed with a 0 then that call gets routed off network - (as an example). As far as cost goes, depends on the ammount of ports you require

Hopes this helps

Hi

PABX or POTS

This is one and the same thing

Again guys ... it's worth to look at TelFree ( http://www.telfree.co.za/ )

Edited:

So you can set up a SIP trunk from Asterisk ... so you don't need any FXO cards/gateways .. just IP connectivity

You could also try http://www.vox.co.za/

They have VoIP phones

Have you done this successfully? I am having trouble with getting my Asterisk box to register with TelFree. I'm also having codec troubles.

yeah mine is running 100% .... here is my config from /etc/asterisk/users.conf (Asterisk 1.4):

[trunk_1]
disallow = all
allow=g729
context = DID_trunk_1
dialformat = ${EXTEN:1}
hasexten = no
hasiax = no
hassip = yes
host = sip99.telfreesa.com
port = 5060
registeriax = no
registersip = yes
secret = xxxxxx
trunkname = Custom - TelFree
trunkstyle = customvoip
username = 87750xxxx
callerid = 87750xxxx
fromuser = 87750xxxx
fromdomain = sip99.telfreesa.com
permit = 196.46.138.29/29
insecure = very
qualify = no
canreinvite = no

I have done most of this using the GUI (http://www.asteriskguru.com/tutorials/asterisk_gui.html) and then added a few things later on.

I had to purchase a G.729 license ($10) .. not that bad (http://www.digium.com/en/products/voice/g729codec.php)

Obviously, you have to replace the "xxxx" above with your details.

This works very well for me ... as my family can now dial a local 087 number (R0.59c / min from Telkom line) and it rings directly on my SIP phone (on the living room floor at the moment . Normal Telkom rates to the UK is about R9.00 / min, so works very well for me !

Good Luck.

Are you sure about Telkom's rate to the UK.
