How would I transfer an extension through a T1 card? We have a phone system at different sites. They are connected through a T1 card but Im not sure how to link an extension from site to site.
 
If it's not programmed to call site to site when dialing extensions already- which would allow you to just dial an extension and it would recognize it as being at the other site and route it over the T1- then you need to program UDP (uniform dial plan) and each site needs unique extension numbers.
 
If you can already call site to site and have added a new user, you need to make sure that the number matches your existing uniform dial plan. You can do this by either looking at the UDP as a report generated by WIN SPM (the easiest way) or scroll through the system renumber options until you get to UDP and check it by location there. WIN SPM is the best way.
