[question] external FXO/FXS with CLIP (CID) Support both ways

[pt-1]

Hi,

playing around with Asterisk and I am looking for a cheap FXO/FXS Adapter that enables me to connect my Landline (FXO) with Caller ID and a Phone (FXS) supporting CLIP so I can see my incoming calls on the Phone LCD.

Seen a few ones on Ebay but not sure what to buy

My favourite at the moment is the Linksys SPA3000. It plugs in to your BT Line, your router and a plain old telephone. Costs about £25 delivered from Hong Kong via Ebay and is slightly more expensive than a PAP2.

Works fine as a standalone box or with configuration it is ideal as a 'breakout' to BT via Asterisk. I have used time conditions in Freepbx to only allow calls to be made via BT after 6 and at weekends (when my calls are free).

Getting a Linksys SPA 3000 working with FreePBX can take a long time to setup and configure. To make this process easier for UK users, I have uploaded my SPA3000 configuration.

To use the configuration , click on this link (will open in another window) you should use the 'Save Page As' option by right mouse clicking in your browser.

When downloaded, you will need to make a number of changes using a text editor.

Search the html file and replace :-

Search Replace with

A.A.A.A Line1 Proxy IP address

BBB Line 1 Display Name

CCC Line 1 User ID

DDD Line 1 Password

E.E.E.E PSTN Proxy IP address

FFF PSTN Display Name

GGG PSTN User ID

HHH PSTN Password

III PSTN Dial Plan 2 insert YOUR PSTN number

J.J.J.J IP Address of the SPA3000

When all of the details have been entered, open the file in your web browser and click on

"Submit all changes" at the bottom of the screen. This should write all of this data directly

to your SPA and also leaves you with a full backup should you create a configuration problem later.

To configure FreePBX, I followed the 'How To' on the FreePBX forum. The page is long and quite complex so I have simplified the settings below

In Trunks create :-

This allows for calls starting 01, 02, 03, 050, 080, 0870 and 0845 as well as any 6 digit number.

disallow=all
allow=ulaw
canreinvite=no
context=from-trunk
dtmfmode=rfc2833
host=dynamic
incominglimit=1
nat=never
port=5061
qualify=yes
secret=xxxxx
type=friend
username=1-pstn

Replace secret=xxxxx with the PSTN password used on the SPA-3000 (HHH).

Leave Incoming Settings and Registration blank.

For the Inbound routes setup the following.

Note the DID Number must match the number entered as III in dial plan2 of the SPA-3000

The BT route is a normal incoming line and can be sent to any destination - I use an IVR

does it present the Caller ID on your BT Phone on the FXS end ..?
does it receive the Caller ID from BT and you can use this in Asterisk?

CLID on BT is passed to Asterisk without problems, and CLIP works fine on the phone - so yes & yes (I would not have posted if it did not)
