Hello Takeshi, Thanks very much for your extensive reply. You spelled out all the facilities I had hoped to find; not sure why I overlooked them in the docs, maybe I looked in a wrong place. Anyhow, SIPP found me impressed :-)
I can now confirm that SIPP can be used as a UAC and/or UAS to wrap around a codec like the one I made. In case anyone needs a similar facility, I've included the scripts that worked for me, based on your examples. Thanks a lot! -Rick

uac.sipp
This is a scenario file for SIPP version 2.3. Invocation:
sipp [::1]:5060 -i [::1] -sf uac.sipp -m 1
Replace [::1]:5060 with the remote peer's SIP address/port.
Replace [::1] with any IPv6 address to use for SIP and RTP.
It sits and waits for incoming Realtime Text SIP calls,
and starts the test utility from the local directory
when one comes in. The call ends when the remote end
takes the initiative to do so.
This is hardly a functional phone, it is just an RTP
wrapper for test purposes.
