I have a customer who is having COT lines(analogue lines) from Telco in his PABX in the existing environment. Due to business requirement the customer wants to retain the COT lines while moving to the Cisco IPTEL environment.
For which I think FXO card/ports is the solution in ISRG2.
But the customer has too many COT lines, for e.g. for one site he has 150 COT lines.
1.Can somebody suggest how to cater this with ISRG2.. how many max FXO ports/cards can ISRG2 cater.. I am ready to put a higher end box if it solves the purpose like 3945 etc.
2.Is there any better suggestion to cater COT lines in Cisco IPTEL Environment.
