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

added docallbacks flag in q931decode

backport from trunk rev 239037
add docallbacks flag in q931decode function because
we must do callbacks when we decode received q931 packet and
we must don't when we print sended q931.
