hi
these steps were mentioned in Nortel NTPS to change the payload value of RFC2833 for DTMF on SIP trunk to be compateple wiht CCM.
the problem if i cahnge it from the PDT by using setRFC2833 it will work but after i reboot the system it will go the default payload.
these steps as per Nortel NTPs
1 Locate the start up file named /p/startup
2 Type the following command the file at the end (where nnn = the
payload type value)
setRFC2833PT 102 <enter>
3 INI (or coldstart) the Call Server.
4 During INI, press CTRL+B when prompted, then press c to change
the parameters. Press <enter> until the start up scripts prompt
displays.
5 Type /p/startup <enter>. Continue to press <enter> until the end.
6 Press @ <enter> to continue to reboot.
thanks.
