[Freeswitch-users] Wrong RFC2833 in SDP on NEC phones

Some Nec phones sends DTMF RFC2833 with payload 101 during the call, but have negotiated a different one on SDP.
When integrating with pabx NEC SV8500 and using phones DT700ITL32D-1 we notice this phone sends the following INVITE packet and RTP packets: http://pastebin.freeswitch.org/11433
Whole wireshark capture file is on http://gregianin.org/teste_voice_rfc2833.pcap
Is there any parameter to tweak FS in such a way to force understand 101 packets as DTMF?
Thank you in advance!
PS: On pcap you have the following IPs:
FS at 10.91.10.210
Nec Pbx 10.91.10.22
