is further adapted to divide telephony trunk 21 on the ilec side into a plurality of smaller trunks 25 a 25 n on the isp side in this example trunk 25 a connects pabx 19 to pm 31 for data calls a trunk 25 n connects pabx 19 to voip gateway 29 for voip calls pm 31 is adapted to convert data events arriving from pabx 19 over to ip data events for ip delivery over backbone 37 voip gateway 29 is adapted to convert voice calls arriving from pabx 19 to voip calls for delivery over backbone 37 ss 7 protocol provides the rules and routing instruction for the gateway conversion and delivery of all events entering the network represented by backbone 37 similarly all ip events entering domain 10 from network 37 are converted and routed according to ss 7 protocol in this prior art example an ip router 41 connected to backbone 37 represents a first ip routing point in the internet network for voice calls arriving thereto from voip gateway 29 over a data trunk 35 n similarly an ip router 39 connected to backbone 37 represents a first routing point for all data events arriving thereto from pm 31 over a data trunk 35 a trunks 35 a n represent local data trunks it is recognized that there may be more gateways strategically connected between pabx 19 and ip routers 41 and 39 than are illustrated in this prior art example the inventor illustrates only one pm 31 and one voip gateway 29 in this example for descriptive purpose in explanation of this simplified prior art configuration fig2 a is a block diagram illustrating components and functions of pm 31 of fig1 pm 31 as previously described.
