I've got an issue with an sx-50. its not internal calling or external calling. External calling meaning when I dial 9 to work access a trunk. I have the trunk groups set up correctly. Its just odd. Could it be a bad Control card. I have looked through manuals and I dont see anything related to my issue.

1. Rotary dial phone without rotary enabled.
2. All DTMF receiver/senders broken/disabled (Should have seen alarms!).
3. Can the console call rooms and/or make outside calls?
4. Program hosed, possibly from power glitch and dead memory battery.

Could be related to the Console loop back alarm i'm getting.

Remember that the console DOES use the DTMF sender portion of the sender/receivers. First, I would reboot. Second, pull ALL periphial cards, WITH THE POWER OFF, and test. Then reinsert 1 card, WITH THE POWER OFF, at a time and test. Third, I would initialize at least 3 times, then reprogram. Just enough to test! No help, time for a replacement MCC.

I'm assuming that this is/was a customer's working system, rather than an e-bay type purchase!

OH Yeah, check Power Supply Voltages before going too far, like after the reboot doesn't work!

It was a bad Main Control card.

Oh well, it's only money.

Yup, Thanks for the help!
