Calling out on line port not working from SP
rjdyck:
I am trying to decide if if I have a bad obi110. This is a new unit. I have some experience with a SPA3000 so this really is not very new for me. I want to be able to call in on an SP and get PSTN dialtone.
This works - SP1->AA->LI
This works Phone->LI
This doesn't work - Sp1->LI
No fancy digit maps. The SP1 inbound route is simply LI
I am connecting to the PSTN alright. I hear a little bit of line hum for a few seconds and then a recording saying "the number you have dialed can not be completed as dialed".
I tried (<@:>):li to eliminate any digits but it didn't help.
Any suggestions?
One other unrelated thing, The Obi can not detect an offhook on the phone line. I played with the voltage settings to no avail.

I'd guess that message is coming from your PSTN service provider.
Log in to the OBi's local web interface. Click on Status, then on Call History and see what digits are being dialled on the LINE port.
Normally an InboundCallRoute would send CallerID as DTMF tones to the called terminal. Could that be what your PSTN service provider is receiving and rejecting?
rjdyck:
The call history shows no digits dialed.
SP1 inbound ringing
line1 outbound connected
A PSTN line never receives caller ID it only sends it and caller ID is sent as FSK not DTMF.
When the line receives a "call for service" ( a loop ) it attaches a DTMF receiver to the line. The receiver is not capable of reacting to FSK even if it was sent down the line. However the DTMF receiver is capable of receiving legacy dial pulses. My guess is that there is pulse on the line ( loop, break, loop ) and the receiver interprets as a digit 1 ( if it was a single pulse ). A single digit other than 0 does not match any dial plan and it times out waiting for more digits.

When you set InboundCallRoute to 'ph', the OBi sends the Caller's number, if available, to the phone. That can be sent to the phone as DTMF tones if that method is selected on the OBi under Physical Interfaces, Phone Port, Port settings, CallerIDMethod. Yes, DTMF is unlikely to be selected in N.America but your use of the term 'PSTN' rather than 'POTS' suggested (but admittedly does not prove) that you might be elsewhere in the world. I wondered if, when InboundCallRoute is set to 'Li' it would also attempt to send the Caller's number.
That the Call History does not show any dialled digits is not surprising.
Possibly the explanation is that the OBi does not implement the 'dial through' functionality in the same manner that you are familiar with on the SPA3000. Most people use the OBi's AA to bridge incoming calls to PSTN dial tone.
I would expect that setting InboundCallRoute to, say, 'Li(1234567890)' would cause 1234567890 to be dialled on the PSTN line but I have not tried to verify that.

Don't confuse the functions of the phone port versus the line port. I agree the phone port can send caller ID.
The phone port receives digits from the phone ( DTMF ) ( outgoing call ) and it sends ring ( AC voltage ) followed by callerid ( FSK ) ( incoming call ) to the phone.
The line port sends digits that it received from the phone or VOIP or AA to the telephone line ( outgoing call ) and it receives ring ( AC voltage ) and callerid ( FSK ) from the phone line ( incoming ).
I want to receive the actual dialtone from the PSTN and then call the number of my choice using the keypad of my softphone. In other words the Obi should simply bridge the SP and LI. The DTMF from the softphone simply passes through the Obi to the receiver in the telco central office. The Obi is indeed bridging the SP and the LI because I hear the the telco's recording. The telco has received some unknown digit and is waiting for more to match some dial plan.
