I've read plenty of documents on Time of Day Routing for our CUCM and most of them mention translation patterns etc.
We have a set up where we have external ringers on our buildings that work via an ATA187 connected to our CUCM.
These ringers are in a hunt group that also call internal phones during the day. We needed these external ringers to turn off at night so as not to disturb residential properties nearby but keep the internal phones ringing.
Lets say the internal hunt pilot for the above group is 1000 and is in pt_internal partition which is always on.
What I did was:
1. Create time time periods 2000-2400 & 0000-0800
2. Add those to night time schedule
3. Create pt_night_partition
4. Assign night_time schedule to pt_night_partition
5. Add night partition into CCS's that were relevant and ensured that pt_night-partition was BEFORE pt_internal_partition
6. Create new line group which had the internal phones but not the external ringers
7. Create new hunt group which had the above line group in
8. Create new hunt pilot (with same number hunt pilot with external ringers in eg 1000) and assign it to pt_night_partition
So because the pt_night partition is ABOVE the pt_internal partition, when the pt_night partition is active ie 2000-0800, the hunt group without the external ringers is called first. When it's not active, the hunt group (on pt_internal) with the external ringers in it is called.
This is working without any number translation (as mentioned in other docs) so I'm wondering if there is any downside to it?
