Out-Going Calls With Call Coverage Setup

Recommended Posts

We are using VG 7.5 with a 12 port Dialogic D/120JCT LS board. Only outgoing calls are made. We have four phone lines, of which one is not being detected as a valid line by VoiceGuide. (In the CallEvents log we see "working phone line not attached" and can view call processing via the line monitor but a call is never made to the phone).


We have tested the board port and have validated that calls can be made from the "bad" line (by hooking the phone line to a phone and making calls out). This line is set up in the coverage path for another line, as previously in-coming calls were set u, but are no longer done. Why can't VoiceGuide detect that a valid line is attached to the port? I have attached log files.

Trace shows that when an outgoing call is attempted on port 4 the following error is raised:


ALERT Loop current not present. Working phone line not attached.


So either the line currently attached to port 4 on this system has a break in it, or the port on the Dialogic card is faulty.


You mention that:

We have tested the board port and have validated that calls can be made from the "bad" line (by hooking the phone line to a phone and making calls out).


So sounds like you have you been able to place outgoing calls over port 4 when some other line was attached to that port?


Please try unplugging the line cable from port 4 and plugging it into (say) port 1, and attaching the cable that was in port 1 into port 4. And then try placing outgoing calls to both ports again. If port 1 is now having problems instead (and port 4 works fine) then you have shown that the problems is in the line wiring, and that the cable that attached to port 4 originally needs to be replaced.


Is the problem intermittent at all? Solid copper wires can develop hairline fractures if they have been bent a number of times, and this is the most common cause of intermittent type problems.

Thanks you for the response.

We performed the test you suggested, (swapping lines in the bad port with one that was working) and the port that was working now fails, while the other (bad) port now works.


Our line problem is not intermittent. It always occurs on that phone line.


We changed the physical phone cord and re-tested making an out-going call, but got the same result.


Anything further we can try?

That would suggest that the issue lies with the device/PBX from where those lines originate.


Or, if the "physical phone cord" was not plugged directly into that device/PBX, then problem may lie with the wiring between that device/PBX and the wall socket to where the "physical phone cord" was attached.
