Phantom Dahdi calls after hangup

Asterisk Asterisk Support
1

On more than one occasion I have had “phantom” calls from unknown, unknown on dadhi channels after someone makes a call and either party hangs up. I have tried fxotune and used oslec on the channels that have the problem.

Dahdi is 2.4.0 and asterisk is 1.6.2.16. The channels were on an Astribank with 8 fxo ports and a Sangoma u100. I thought it was just a really bad line in the building in question but I was able to reproduce the symptoms at a different location.

The CLI shows the channel in question “spawning a new” connection on dahdi x-x.

What would cause behavior like this? What might fix it?

I am having a similar problem. The CLI show doesn’t show that my extension is receiving a phone call, but my cordless phone lights up, not ringing, though. After which I get ‘1 missed call’ in the log on the phone. Did you ever find a fix for this?

You need to provide your chan_dahdi.conf settings, details of your PTT, and a log with sufficient debugging to show the line state changes seen by the FXO card (if you don’t see “battery” in the traces, they are not detailed enough).

The phones I have connected is a AT&T DECT 6 phone, and an Aastra 470 via line splitter. I only get the phantom call back on the Cordless, though. It happens if I hang up either phone, whether its after a successful call, or just checking for dial tone.

Addendum:

while running dahdi_monitor, I found that when the phone gets the "call"s, the TX and RX both almost max out right before the phone starts to blink
