VTSP is ?

With Cisco 3662, there are VPM and VTSP.

I guess that VPM manages Signalling on the links and VTSP may manage call control...

And VTSP has Finite State in opration.

S_SETUP_REQUEST -> S_SETUP_REQ_PROC -> S_R2_DIALING -> S_SETUP_REQ_PROC -> S_CONNECT -> S_WAIT_STATS -> S_WAIT_RELEASE -> S_CLOSE_DSPRM

Is there any documents describing the operation and finite states of the VTSP, and its functions?

Re: VTSP is ?

VPM is the voice port module, the state machine that controls the voice ports and VTSP is the telephony state machine, a layer deeper than VPM.

We don't generally provide customers with documentation on the internal functions of gateways and routers. You can get a good idea of what these are doing by running 'debug vtsp all' and 'debug vpm all', do this on a lab router or one where you can make sure that you will only see one call at a time.
