I am planning on upgrading a UC520 from 8 FXO lines to a Voice T-1 PRI with 40 DID Lines. I ave some questions regarding this upgrade I hope I can get some answers to.
Where can I find documentation on this upgrade ? I am also keeping 4 copper lines for failover. Will the UC520 be able to automatically failover to the FXO ports if the T-1 line goes down ? Can I can configure this with CCA ?
Anything I should know to ask the vendor regarding the T-1 Specifications to make sure it will work with the UC520 T-1 Wic card ?
Thanks for your assistance.
