We have a CX3300 system and a single sip trunk coming in/out.
We have two buildings on one campus and all phones from both locations go out the same CX3300.
Currently all phones are on one VLAN but this could be separated into two VLANs one for each building.
Looking for a way to have one building use it's CESID and a different one for building two.
In a perfect world, it would be nice that if the phones are transported from one building to the other, it would automatically update what CESID it will dial out. Is this even possible and if so how?
If this is not possible, what is the best option/practice to setting 911 in this scenario?
