Summary:                    One way voice after attended transfer
Description: 
We have problem with one way voice in next scenario:
101 calls to 102, 102 takes second line and calls to IVR (number 1234)
that have Answer() application and then call directed to 103
102 makes attended transfer while 103 is ringing, so now we have call
between 101 (connected) and 103 (ringing)
when 103 answers we get in CLI bulk of messages:
[15 12:33:10] WARNING[3681] chan_sip.c: Asked to transmit frame type 64,
while native formats is 0x8 (alaw)(8) read/write = 0x8 (alaw)(8)/0x
8 (alaw)(8)
101 can hear 103, but 103 can't
only if 101 press any digit (sends DTMF) or press HOLD and UNHOLD, then we
have two way voice.

101, 102 and 103 are SIP devices
I attached full log with SIP debug

    When a channel is answered make sure any indications currently playing
stop. Usually the phone would do this but if the channel was already
answered then they are being generated by Asterisk and we darn well need to
stop them.
