Recommend a Analogue gateway for 3CX

[h2009]

Can anyone recommend a simple, very reliable analogue gateway to be used with 3CX. I only need to connect 1 analogue line to the system.

Hi

As a single port device you can use the Linksys SPA3102.

Simple and easy to configure. see http: //www.3cx.com/sip-phones/linksys-spa-3102-fax/ No longer available. New link:http://www.3cx.com/sip-phones/

 

[h2009]

I've used the linksys spa before but I didn't find it was reliable enough for my needs. Any other recommendations?
I will be using to pass all calls so it need to be able to cope.

 

[h2009]

Could you provide a link directly to the patton box please?

 

[h2009]

I've dug out my old SPA3102 unit but I still cant seem to get it to work with BT over in the UK.
I've looked around for settings but it seems that the FXS needed is missing?
Has anyone managed to get this unit to work in the UK?

Has anyone managed to get this unit to work in the UK?

Been using one for a good while now - completely trouble free. What problems are you having?

 

[h2009]

Right well at the moment the unit is connected to the network (via the internet port on the unit). In the 'line port' i've connected it to the BT socket, and phone to an normal phone.

I can get the unit to register on 3CX, but when calling my landline number the call isn't passed to the 3CX nor does it ring the phone.
If I try to make a call on the phone (connected directly to the unit) there is no dial tone.

I've followed this guide: http://www.aoakley.com/articles/2008-01-08.php to configure it to work with BT but in the FXS Port Impedance part I don't have the option for 370+620||310nF as needed due to the latest firmware 5.1.7.

There is nothing appearing on the 3CX logs to show that calls are even being routed to it. Also on the status page for the SPA unit, it doesn't show a call being detected when the line is ringing.

If you could you please could you tell me exactly how you've managed to get yours working? Even provide screenshots?

Thanks

I've followed this guide: http://www.aoakley.com/articles/2008-01-08.php

Some of what is in this guide is not correct for a 3102 that needs to work with 3cx. Attached zip file contains a complete config of my unit saved as an html file so you can click on all the tabs. FYI my 3cx machine is 192.168.1.150

Hope this helps!

Thanks for that, I'll give it ago and hopefully it will be working!

Just once quick question in 3CX have you got the PSTN gateway port set as 5060 or 5061?

Thanks

 

[Cjay]

PSTN port set for 5061. FXS port on SPA3102 runs on 5060 to be consistent with all my other phones (well actually I don't use it).

I've input all the settings, and everything is work now apart from routing calls over the PSTN line.

Thanks for all your help so far it has really help

Here is the log: (192.168.0.200 is the 3CX, 0.184 is the SPA)

There's a few things that could cause this behaviour - but check that you don't have some remnants of a dial plan remaining in the VoIP to PSTN Gateway setup section in the 3102.

 

[h2009]

Hi, I've checked all the settings again, and they have all been input correctly. I've given 3CX server a restart and tried the SPA on another PSTN line, but no luck.

It seems that when trying to dial out from a voip phone, the system doesnt even attempt to dial the numbers at the SPA unit and 'send' them.

 

[Cjay]

What outbound rule are you using for the 3102 / BT line?

 

[h2009]

3CX's outbound rules:

Any number with prefix 0 - Route 1 = BT (strip set to 0)

 

[Cjay]

Hmm, time to ramp things up a bit....

What settings do you have for PSTN devices (including general, advanced & outbound parameters)
Also be nice to see a full config of your 3102 similar to what I posted.
If all else fails are you able to do a wireshark capture of the dialog (if any!) between 3cx & 3102? (I keep a copy of Wireshark on my 3cx server for tricky problems like these. You only need to capture on port 5061)

[h2009]

Here are some screen captures of the 3CX of the PSTN device.

 

[h2009]

Here is the linksys configuration file page.

Thanks again for your help.

 

[Cjay]

Your SPA3102 config file contains links to the IP of your device so I can't use it. You need to (in Firefox anyway!) do a 'Save Page As' and select 'Web Page, HTML only'. That way I can open and click through all the tabs.

Oh very sorry about that. Here it is:
