[cisco-voip] DR Telephony Solution

[Cauthen, John A.]

Looking for suggestions and ideas:

 

We would like to implement a disaster recovery solution for our phone
system at our DR site.  We are a medium size business with about 300
users and one primary office location.  We have a dedicated 100MB
connection between our main site and the DR site (same subnet).  We do
real-time replication of data (SAN to SAN) and backups over that 100MB
connection which usually stays around 10MB usage during the day.  

 

Ultimately, we would like to place our Publisher and Unity Connection
servers over at the DR site with a router (GW) so, that if we lost our
main site we would still have our phone system.  We currently have 4 T1s
and are using MGCP.  Would it be more beneficial to move to SIP or does
it matter?  Would this work or is there a better solution out there?

 

Our current phone system consists of:

2 - CUCM 6.1.2 (Publisher and Subscriber)

1 - Unity Connection 1.2(1) SR2

1 - Contact Center Express 5.0

2 - Cisco 3725 routers (total of 4 T1s) MGCP protocol

 

Any suggestions or feedback will be greatly appreciated. 

 

Thanks,

 

John
