outgoing calls as packets to one or more ip addresses that is the gateway may be directly incorporated within the legacy pbx in various embodiments of the present invention a virtual pbx vpbx 205 is provided typically as an internet connected server executing a rich software suite sw 2 and outgoing calls from legacy system 105 are addressed in the translation by gateway 201 to vpbx 205 in a similar fashion pstn calls represented by arrows 102 and 104 destined for legacy pbx 107 from pstn 100 which may be via a service control point scp 101 or another pstn switch 103 go to a supplemental gateway 208 associated with vpbx 205 and are translated to sip or other packet protocol and managed by the vpbx other incoming may be packet protocol telephone calls 211 all these incoming calls are forwarded to gateway 201 via internet connection 206 and are translated back to pstn protocol and delivered to legacy pbx 107 the skilled person will understand that gateways such as 201 may be programmed to address packet calls to vpbx 205 where a broad variety of enhanced services may be provided for legacy system 105 further in an embodiment of the invention services at vpbx 205 are configured.
