together and are available for calls to the PSTN as well

• 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

Enhanced Address Manipulation

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
