Hello All,
my infrastructure is composed of some sites spread out to European continent, recently we have unified our corporate directory, however I am looking for some solution for provide basic call-handling support for Cisco Unified IP Phones when they lose connection to IP internal gateway.
I will explain better:
I am thinking some MGCP on our gateway located on headquarter, so if they lose the connection (Call On Net) I can route again through flow primary ( PSTN in off net), but in this case I must prepend the first four digit, in the specific when I press 12345 I hit some intern in Spain in On net, if I lose the connectivity to IP internal gateway I will be route toward flow primary though ISDN but prepended to some prefix digit ( now in OFF NET the pattern in ISDN should be +330455 12345)
Can someone address me? This high avalability is eligible in some way?
