I have a customer who has an SV9100 (ALL IP PHONES)
about 4 or 5 locations with just IP phones at those locations

its a dentist office and they are only using those other sites a couple of days a week and other companies are using them on different days

is there a way to do a port swap on virtual extensions or possible a digital extension port (no phone)

so that someone from the other company could log into to a phone and change the outbound caller ID which would be programed in 21-13-00

I haven't tried to do a swap with a phone that's not plugged in

would be a pretty cool feature for customers who share office space

I believe this would work fine on Avaya IP Office

Be better to just use night modes to do all this.

that sounds good, do you think the end user can keep up?

use the IP phone hot desk feature on the system using the exit key (Hold this in for a few seconds) as a logout button, Ensure that the login mode is set to manual for IP Phones, and that you have login ID's associated to the extension numbers. you will need to ensure that you have enough system port licenses for the number of users you wish to use. This is a key point with the SV9100 and differs from the 8100 as it is not a concurrent user license when you log a user in it locks the license to that user.

Thanks I will try this the next time I am out onsite
