Multi-Site UC560 Deployment

[David Linardy]

The Scenario

-My Customer has  2 sites with Less than 50 user each.

-They currently 3 digit dial between the two locations with their existing phone system (NEC) and the use of a PTP circuit.

-Site 1's extension range is 100-199 & 300-399, Site 2's extension range is 200-299.

The Challenge:

-The Customer would like to take advantage of Cisco SBCS and have all interoffice communications be handled by sending gateway to gateway voice traffic over a VPN , and eliminate the exorbitant cost of the PTP...

-THEY WANT TO MAINTAIN 3 DIGIT DIALING

The Question  

-I was told that you must 4 digit dial from location to location via a location # (1 or 2).

-Is there a way around this? Can my customer maintain the 3 digit dialing?

Any configuration help offered is greatly appreciated!

Best Regards,

David

HI David,

if you set up site 1 as extension range 200 - 299 and site 2 as 300 -399 and use the UC540/560 multisite then the default intersite dialing will be

Intersite access code + site code + Extension.

ie from site 1 to site 2 extension 301 you ould dial 82301

and from site 2 to site 1 extension 275 you would dial 81275.

BUT

to keep the 3 digit dial you can setup floating extensions in site 1 from 300-399 that do a forward to 82301-82399, you can even give them the same names as the names on the other system and vice versa on site 2

So from site 1 to dial site 2 extension 301 they ould just dial 301

this then is floating ext 301, which is a divert to 82301 and then the UC on site 2 handles the call as normal.

It does give a bit more management on the systems in having ro create each extension 2 and such but it works and we have used it at several customers and after all thats what juniors or trainees are for

Hope this helps
