I have an ISDN PRA provider who wants from me the following:

- we discuss about differents boards PRA, PRA2, NPRAE on various 4400 or OXE
- now, my PABX it is programmed to look up for "Bearer Capability" (Speech) in Call Progress (CPG)
- ISDN provider wants that my PABX look up for "Bearer Capability" (Speech) after Call Answer (ANM) or both

Do heard about that or can you tell me how to do it ????

Have a great weekend !!!

I was thinking about Other system parameters / External signalling parameters. Did you see something interesting here ???

And it`s possible this ???
Can support UUS in SETUP
- SUU negotiation is performed by sending the User to User information item in the set up.
- Some public exchanges do not accept this item and refuse the communication.
- In this case, set it to NO.
