[asterisk-users] Two Extensions showing as Busy

[--[ UxBoD ]--]

Hi,

had a very strange issue today where two extensions called each other, hung up, but on another extension the two parties continued to show as busy.

This was running Asterisk 1.6.1.12 and when connecting to the console we saw :-

All extensions were within the same context.

Has anybody seen this behavior before and what could cause it ? we resolved the issue by sending a SIP notify reboot to the SNOM phones.

Thanks, Phil
