Hi All, a quick couple of questions for a VOIP noob.

I want to have a play with trixbox and would like to connect it up to my Telecom POTS line. I've got a POE midspan switch, the house CAT6 cabled and a few Cisco SIP phones. I've had trixbox running and transferring calls to the Cisco phones ok and now want to have it answer all incoming calls and distribute the calls via IVR to either an IP phone or all analogues phones connected to the house POTS system.

Can this be acheived with a PAP2T or similar? My problem is that the asterix server is in the garage and the phones line are in the house. I do have the garage CAT5 cabled but would prefer to leave the POTS in the house and route the POTS line over the network. That way I only need to run the adapter in the house a plug a dect phone into it.

After having a play with this configuration I'd like to subscribe to something like VFX and route some outgoing calls through their service and maybe have an additional VFX number that routes some incoming calls (based on called ID info) directly to my office.

Does anyone know if the above is easily acheivable? and if so would it also be able to be run in a VM? Ive found a few different "Trixbox for Dummies" tutorials but all appear to have an X100P in the mix.

Any help would be greatly appreciated.

Thanks

Chris

Perhaps if I explain (as best I can) what I have it may help.

I have a Panasonic PABX in the house and a Trixbox setup. I have a WAG54GP2 router terminating the ADSL connection, which has one of its VOIP ports dedicated to VFX and a standard phone connection from that VOIP port into trunk 3 on the Panasonic PABX. Trunk 4 on the PABX connects to Trixbox via a Handytone AT386 (leaving a spare FXS port available) which is defined as an extension (eg 500) in Trixbox. So by dialing 500 from any of the VOIP phones I connect to the PABX as a regular incoming call and the ringing is determined by the PABX programming.

Calls from VFX are handled by the Panasonic PABX and not Trixbox. Calls from my other providers such as 2Talk, Freecall etc are handled by Trixbox and it directs incoming calls to the VOIP phones and to the PABX via the AT386 connected to trunk 4 (ie ext 500) depending on the selection made from my IVR menu and the associated Ring Group, which can include or exclude the PABX.

The reason I do not handle VFX from Trixbox is the echo on the x100p cards. There is a more expensive option using TDM400p cards which reduces the echo, but I still found it a problem. So I do not handle VFX calls using Trixbox at all now. If they ever allow Asterisk access for small users to connect to VFX directly I will use them more.

Right now, I connect to 2Talk straight from Trixbox and its working fine. To access VFX I just select trunk 3 on the PABX handsets and that selects the VFX trunk via the WAG54GP2 router. To access 2Talk from a PABX phone, I select Trunk 4 on the handset, which accesses the trixbox and I then just dial out in the normal manner and let Trixbox decide which of my VOIP providers to use for the call depending on the number dialed.

So far its worked very well. Hope that helps.

Cheers Mike

Thanks for that Mike....your config sounds like you are controlling your calls with your analogue PABX and using Trixbox to just route the calls dependent on which trunk (outgoing line) you select on your PABX. If it works for you thats great.

I think I may be able to use a Linksys SPA-3102 to connect the PSTN lines in the house to a Trixbox in the garage. The SPA-3102 has both FXO and FXS ports so should do the trick. The only thing Im converned about is there may be a bit of echo but as im just playing around im not too worried about that initially. Otherwise it looks like the TDM400P is the way to go but I will have to divert some copper out to the garage where Trixbox is.

Im surprised no one else has an opinion on this setup as It seems to me to be a likely first step into the world of VOIP with Trixbox. Im prepared to purchase regardless and give it a try anyway. At least this way if things dont go smoothly I can just unplug the ATA Adapter and carry on with my existing phones.

Thanks for your input

Chris

Maybe I should read your question... His post doesnt cover this...

Basically you want a FXO to Sip Adaptor...

Im pretty sure the Linksys 3102 will do this.

@dimsim: I use Trixbox to control all of the incoming and outgoing calls on VOIP circuits with the sole exception of VFX calls which the PABX handles. The PABX also handles all calls from the PSTN - but does not pass those through to Trixbox. The sweet spot would be to get the FXO working without echo, so that even the PSTN calls can be directed to Trixbox bypassing the PABX. That is what the x100p or TDM400 is supposed to do.

Let me know if you get the FXO component of the 3102 working without echo. I will be interested in looking at that as an option.

PS: As an FXS option, the Handytone's take some beating. They are quite cheap and the quality through them is very good. Having said that, the 3102 is well respected.

Cheers Mike

Thanks Mike, I will let you know how the 3102 performs. Unfortunately the 3102 is out of stock at the minute but should be here in a few weeks.

Cheers

I dont imagine you will have to much luck with the 3102 without Echo...

I orginally tried the x100p, and got echo, then a TDM4000, that was pretty good. Then we upgraded to ISDN, where we now use a Quadro ISDN box, that has echo almost as bad as we got with the x100p...

In saying the above, others have had sucess with the x100p, I guess it all depends on your line quality...
