DND does not work for SIP trunk calls

[eugenej]

I'm unable to get DND to work for SIP trunk calls to an ACD station. I've tried the setting in system options form not NOT allow override but I guess the SIP trunk does not fall in the "supported" trunk type category.
Anyone got this working somewhere perhaps.

Not sure to the extent but I do know that SIP trunks are not treated as 'trunks' in some cases; they are treated like private IP trunks rather than public trunks  (system to system which is probably why they are not treated as public trunks) IIRC. Call length timer being one. Is that option available from the station settings. That may have changed in later releases.

Definitely would take a look at COS assigned got he trunks
