Using laptop as landline telephone
ianobi:
Looks like you have the physical connections all sorted now. I cannot see any obvious reason why outgoing calls are not working, but some testing should reveal all. Try:
1. Plug the domestic phone direct into the PSTN socket. Can you make outgoing calls? This will prove the PSTN line and the phone. (Obvious I know, but it's surprising how simple things get overlooked.)
2. With the OBi110 back in the setup, if you take the domestic phone off hook and dial "#" do you get PSTN dial tone? Can you then continue to dial out?
3. When attempting calls from the Phone Port and from the laptop, does Call History show anything? See earlier reply for accessing Call History.
4. Do you live in a rural area maybe a long way from the telephone exchange? (We can adjust for this.)

If I answer on the softphone I get good clear speech on the laptop but the calling end reports my voice is faint and they hear their own voice echoed back to them.
This may be an effect of the physical design of most laptops. The speakers and mic are near each other, so the callers voice may feed back into the mic sounding like echo. It may be worth looking at using a headset or separate speakers / mic so they can be further apart. The mic gain and the speaker volume can be changed on PhonerLite, you have to click on each symbol to unlock it, then move the slider. It's something to look at once we have solved the outgoing calls issue.

The domestic phone works perfectly directly into the wall socket, into the ADSL filter or into the 2-way splitter plugged into the filter. Repeating with the OBi into all of these 3 locations yields the original results: inbound PSTN calls to OBi phone port or softphone fine, no outbound calls from either location.
When I dial # on the OBi phone port I get a couple of seconds of silence then a couple of clicks and then more dial tone, then while I dial a known PSTN number I get silence, but after a few seconds I get pulsed tone but no connection.
When I attempt calls from the phone port I get 2 call records a few seconds apart. The first is for the # press, which lists new call, call connected and end call all in the same second. The second is for the PSTN dialled number attempt, which shows new call and end call in the same second.
Call attempts from the softphone generate no record.
I live in a suburban area - Hove. I get 7Mb/s ADSL from Sky.
We'll get there...

It looks like the OBi110 is having trouble seizing the PSTN line and maintaining the connection. This is odd as it works ok for incoming calls. Anyhow, we are not out of ideas just yet!
Change:
Physical Interfaces -> LINE Port -> LINE Port -> DialDelay: 2000
Physical Interfaces -> LINE Port -> LINE Port -> DialDigitOnTime: 200
Physical Interfaces -> LINE Port -> LINE Port -> DialDigitOffTime: 200
This will give the OBi110 two seconds to seize the PSTN line before it starts dialling and it will dial slightly slower. If it works try cutting DialDelay back to 1500, then 1000. Test from the Phone Port first and check Call History again for results.
Have another look at this:

If you look at Status > PHONE & LINE Status under Line Port Status it should show a TipRingVoltage of around 50v. This is the voltage of the PSTN line.
If the above changes don't solve the problem it may be something else on the PSTN line affecting line conditions. As a test try disconnecting all other devices connected to the PSTN line just leaving the OBi110 connected directly into the wall socket.
I'm away from my PC until around 1500 today, I'll check back here then.
PC10SR:
I tried the suggested changes without any success.
The TipRing voltage is -51v.
What is it that my normal phone does to dial out successfully that the OBi currently doesn't?
Hmmm...
ianobi:
That's a good question! As far as the PSTN line goes the OBi110 Line Port just looks like a phone that goes off hook, puts a loop across the line and send DTMF tones for dialling.
Let's do a Sherlock Holmes on this. We have eliminated most possibilities. About the only thing left is that some sort of line condition, maybe some capacitance, is looking like a PSTN disconnection signal. For now let's tell the OBi110 not to look for any line disconnection. Leave all the changes we have done in place, particularly DialDelay at 2000 and set:
Physical Interfaces -> LINE Port -> PSTN Disconnect Detection -> DetectCPC: uncheck
Physical Interfaces -> LINE Port -> PSTN Disconnect Detection -> DetectPolarityReversal: uncheck
Physical Interfaces -> LINE Port -> PSTN Disconnect Detection -> DetectFarEndLongSilence: uncheck
*Physical Interfaces -> LINE Port -> PSTN Disconnect Detection -> DetectDisconnectTone: uncheck
* Edit: This was enabled to solve another problem - see later posts. New settings are:
Physical Interfaces -> LINE Port -> PSTN Disconnect Detection -> DetectDisconnectTone: check
Physical Interfaces -> LINE Port -> PSTN Disconnect Detection -> DisconnectTonePattern: 400-30;3
You could easily end up as one of the top ten OBi110 experts if this goes on much longer :)
