Enhanced Routing
Support for Any-to-Any routing (SIP to PSTN, PSTN to SIP, SIP to SIP, PSTN to
PSTN)
Defines which CAPI controller is used for which calls from SIP
Increased flexibility of load balancing and failover functionality; load balancing and
failover can be used together and are available for calls to the PSTN as well
Number-based routing also available for calls to the PSTN
Matching rules for number-based routing can contain regular expressions
Routing based on calling or redirected number, the redirected number is only
available for calls from the PSTN
Routing based on Active Directory information
Enhanced Address Manipulation
Define the number manipulation on three different stages of the call routing
(inbound, route selection, outbound)
Unlimited number of regular expressions for number manipulation at each stage of
call routing
Different dialplans can be entered for each controller and each SIP peer, which can
ease the deployment in an environment with multiple locations
