Summary:                    [patch] Random DTMF duplicate emulation on bridged
OOH323 channel on outgoing calls
Description: 
In majority of cases DTMF tones are duplicated by Asterisk when bridging a
SIP or DAHDI channel with OOH323 channel on outgoing calls.

In case of a normal DTMF processing the following sequence is observed:

[Jan 20 19:59:56] DTMF[21084]: channel.c:2855 __ast_read: DTMF begin '9'
received on SIP/464-00000012
[Jan 20 19:59:56] DTMF[21084]: channel.c:2865 __ast_read: DTMF begin
passthrough '9' on SIP/464-00000012
[Jan 20 19:59:56] DTMF[21084]: channel.c:2783 __ast_read: DTMF end '9'
received on SIP/464-00000012, duration 120 ms
[Jan 20 19:59:56] DTMF[21084]: channel.c:2823 __ast_read: DTMF end
accepted with begin '9' on SIP/464-00000012
[Jan 20 19:59:56] DTMF[21084]: channel.c:2839 __ast_read: DTMF end
passthrough '9' on SIP/464-00000012

In case of a problematic DTMF processing it looks like that:

[Jan 20 19:18:54] DTMF[20916]: channel.c:2855 __ast_read: DTMF begin '9'
received on SIP/464-00000011
