Summary:                    DTMF RFC2833 Not recognized
Description: 
We have an Asterisk interconnected with Nextone Softswitch for a few months
now. We recently update to 1.4.29 and now 1.4.37 and we now have problem
with DTMF recognision from nextone site. We 've done some traces between a
working sip proxy with nextone and asterisk with nextone and the only
difference I can tell is the sequnce of the END packages.

Attached:

asterisk_dtmf_trace - Asterisk to Nextone DTMF transmission (not working)
(package nr: 348)

other_dtmf_trace - An other SIP PBX to Nextone DTMF tramission (working)
(package nr: 188)
