Description:	I originally reported this to the asterisk-users mailing list, but given the resounding silence figured it might better go here. I'm running Asterisk 1.4.26.2, DAHDI 2.2.0.2, and libpri 1.4.10.2 on Ubuntu 8.04 with a Digium TE122 connected to my PRI. Note that because this is a production machine, I have not had a chance to update Asterisk to 1.4.26.3. Since that version has no relevant code changes, I don't expect it would make much of a difference anyhow. I have an extension setup so that managers can monitor calls: ---- # grep 9900 /etc/asterisk/extensions.conf exten => 9900,1,DAHDIScan() exten => 9900,2,Hangup ---- For whatever reason, this no longer works. It's not often used, so I don't even know when it stopped working. But now whenever I dial 9900, I just get dead air. The * key works to terminate the call, so I assume the # key is cycling through channels - but even if there's a few calls going on, I get no audio from this extension. Calling 9900 yields this log message: ---- Executing [9900@from-sip-internal:1] DAHDIScan("SIP/7007-08479148", "") in new stack ---- But switching channels logs nothing. I have tested this with ZapScan as well.
