Building your own PBX - Update

I have updated my Building your own PBX article with some additional information and a simple network layout of my system.

Nice. What did you make the layout in?

Also, you didnt include the internet cloud for IAX exchanges.

I didnt include it because I didn't use it for the creation of the article. I am working on a followup that includes that.

Well thats a very good point.

Well this got me started. :-) Any reason why you choose Broadvoice?

Thank you for your nice instructions. Being a noob, this made sense. However, the only part I am not clear on is how you get it to work with VOIP service. I guess I should ask, can you use Vonage, my provider, rather than Broadvoice? If so, can you (or someone) post a follow-up set of nice instructions?

I went with BroadVoice because I only call in-state 99% of the time so it was the cheapest plan.

As for using VOIP providers, I will be doing a followup article soon.

I found the Building your own PBX article very informative, and the added updates did help to clarify some issues.

One thing that wasn't entirely clear to me was -- can you place outbound calls over the PSTN using the equipment you've mentioned in the article (Digium Wildcard X100P FXO card?) Or is this an inbound + VoIP-capable setup only?

I'm eagerly awaiting the followup!

Great article Kerry, I've put the ISO on my old Dual Celeron 433 machine and the Asterisk@Home install even used an SMP kernel. Nice. My card to tie in my PTSN system is ordered from ebay, and I am looking forward to the VoIP update. I use packet8 but I don't think it will be possible to tie Asterisk in with it, they are the only provider with a local number though.

Just FYI, several people on the #asterisk irc channel on the Freenode network told me that the "OEM Digium X100P" cards that are being sold on Ebay for $6.95 (or thereabouts) are NOT Digium cards, that they are inferior generic clones.

That said, the card I ordered seems to work fine for both incoming and outgoing calls with two caveats.

Using the Xten Lite softphone (I'm still waiting for my Sipura ATA to arrive), there's a .5 second latency on calls going through the X100P. That's Xten Lite <-> Asterisk <-> FXO <-> PSTN.

Also, there are periodic pips/beeps at random intervals. EMI from other components in the system?

Disclaimer: I'm not sure if either of these two issues are caused by the clone FXO card. I have no genuine Digium card to compare with.

Anyone else with the same setup (Asterisk@Home + generic FXO card + PSTN calls) care to comment?

I didn't notice any delay when using the cheap card from eBay. I also did not claim that the hardware used would be good for a production environment. The $6.95 cards, in my opinion, are the ideal solution for experimenting and testing or for an inexpensive backup card. You also want good quality components for the rest of the system if it is for production use.
