Summary:                    dtmf_end_only test failing on sip-iax bridge
Description: 
SIP->IAX bridge doesn't send correct DTMF.
Even though _FLAG_DTMF_END_ONLY is set when bridge is set up (checked by
debug), it's lost somewhere on the way.
I'm bridging sip->iax. Sending dtmf from sip fails (only BEGIN is sent,
not END). I've tracked it to channel.c:2390 in *-2.4.8, but can't find any
cause for test failing (END_ONLY not being set):

if ( ast_test_flag(chan, AST_FLAG_DEFER_DTMF | AST_FLAG_END_DTMF_ONLY) ||

    (!ast_tvzero(chan->dtmf_tv) && 
      ast_tvdiff_ms(ast_tvnow(), chan->dtmf_tv) < AST_MIN_DTMF_GAP) ) {

gdb shows, that chan->flags == 512 in that moment.
Any other info needed?

traffic goes: ekiga -> [sip-asterisk-iax] -> [iax-asterisk]
ekiga claims to send RFC2833 DTMF sending
debug log on sip->iax translating server shows same iax frames as other
server is getting and doesn't show any special sip packets
configs are default - nothing was changed in sip & iax apart from adding
accounts
