Thanks for the inputs....

Yes we need the 7200 boxes for QoS . We have developed this test bed for
Voice over Internet Protocol Environment for Research (VIPER) and till now
we have had a subjective testing for H.323, SIP/UDP, and SIP/TCP. We have a
control server that dials and plays the voice files to the gateway and the
core router implements the different QoS techniques to create twelve
different scenarios. We have people judging the voice quality and then
rating them acoording to pMOS values. We also wanted to test the SIP/SCTP
signalling but due to lack of resources now (No IOS Image for 3640 that
supports SCTP) , we have to modify the architecture to accomodate the
existing network components (shown in fig).

Where do I find the ID that describes this mapping of SIP/UDP to SIP/SCTP.
Can you guide me to some resources that explain the implementation of such a
gateway for transport exchange.
