We finally setup our UC520 system and have it running at work. We have an incoming PSTN line and a few incoming voip lines. Both go to the same Auto Attendant except for one DID. Tonight I noticed that after business hours, incoming voip calls would go to the night AA setup but incoming PSTN calls would not be picked up by the UC520, but instead just keep ringing.
What would I have to do to fix this?
