Hi,

TEI Assignment Procedure:

I have been using POTS phones via a ISDN router into a hcf isdn card running 
in NT mode without problems. Recently I aquired a Philips Sopho Ergoline D330 
ISDN phone. Pluging this in in place of the ISDN router caused the phone to 
indicated that its TEI Assignment Request was being denied. Looking at 
libpri-1.0.6/q921.c I discovered that the code could only handle dynamic TEI 
requests, while the D330 was requesting a fixed TEI. I fixed q921.c to cope 
with this but now the phone is issuing a TEI Verify which q921.c is not 
handling.

It appears to me that q921.c is missing quite a bit of TEI assignment 
functionality, so I'm asking if anyone has new code for this or any guidance
for me if I attempt to enhance the code?

This is how my hacked code behaves:
