Where to buy Asterisk Hardware?

I decided to create my won PBX with asterix. Software now runs, but some (1 at least) FXO port is needed.

Where can i buy hardware cards compatible with asterisk. ? Some wildcards are discontinued and other ones, are too expensive to me (180 $).

Thanks

If you are in the UK, take a look at http://www.voiptalk.org

They have the single port FXO card and a good selection of VoIP hardware.

Thanks

I supposed they are "good" people

Do u have references about them ?

They have not this adaptor in stock right now

74 pounds seems to be a little expensive, they have to send it to spain, so it could reach 100 pounds

Well I have got a SPA-3000 from them. I also use their IAXTalk plan for international calls from my Asterisk server.

I am a satisfied customer.

The original X100P FXO card sold by Digium for use with Asterisk is simply an Intel Data/Fax/Voice modem card. You can get the very same modem card at the URL below for USD $7.70 plus shipping.

The same card is also available from several vendors on eBay at very reasonable prices, usually around USD $10 to $15.

If you are looking for a general mail order source of inexpensive Asterisk compatible hardware, such as FXO and FXS adapters, and IP telephones, check out DigitNetworks:

Mind you, they do want USD $39.95 for the very same Intel v92 modem X100P compatible FXO card, which makes buying it from them an expensive proposition.

One important point when you use an Intel V92 modem card that has not been purchased as the X100P card from Digium, but otherwise look identical to it, is that the electronic vendorID read from the card will be different. There are two ways to get around this:

1. If you are compiling Asterisk from source, edit the zaptel/wcfxo.c file as follows:

Existing code:
static struct pci_device_id wcfxo_pci_tbl[] __devinitdata = {
{ 0xe159, 0x0001, 0x8085, PCI_ANY_ID, 0, 0, (unsigned long) &wcx101p },
{ 0x1057, 0x5608, PCI_ANY_ID, PCI_ANY_ID, 0, 0, (unsigned long) &wcx100$ };

Now change the wcfxo_pci_tbl[] in zaptel/wsfxo.c to:
static struct pci_device_id wcfxo_pci_tbl[] __devinitdata = {
{ 0xe159, 0x0001, 0x8085, PCI_ANY_ID, 0, 0, (unsigned long) &wcx101p },
{ 0xe159, 0x0001, 0x8086, PCI_ANY_ID, 0, 0, (unsigned long) &wcx101p },
{ 0x1057, 0x5608, PCI_ANY_ID, PCI_ANY_ID, 0, 0, (unsigned long) &wcx100$ };

The added line in the middle will allow the wcfxo driver to work with off the shelf Intel v92 Winmodem cards as well as with the Digium X100P cards.

2. The other alternative is to make the same modification to the card that Digium did when they turned them into "genuine" X100P cards. Simply carefully remove R13 and R19 with a soldering iron. R13 & R19 are pull down resistors that affects the vendorID number that is read from the card. With these two resistors gone, you now have a card that will appear as a genuine Digium X100P card to the Asterisk software.

Cards purchased from DigitNetworks will already have been modified this way, but then they charge quite a bit more than the US $5 - $15 that one can pick up these Intel Winmodem PCI cards for elsewhere. It is considerably cheaper when you modify the wcfxo driver source code, and/or remove the 2 resistors yourself.

Thanks VelvetFog for the hack.
