Hi Harishkumar,
Thanks for your help. I have disabled speex
codec in ~/.linphonerc, and I can see rtp packets are sending at PCMA
format by using wireshark.
But wrong timestamp is still really high. And no
sound.
I check cpu uage of ARM board is really low.
Any other tips?
Alex

Hi,
check that u have enabled speex codec, u have to disable it.
I faced the problem in similar manner, but after disabling speex codec,
it worked fine.
because, in arm, speex codec takes too much mips, thats what i faced, i
do not know abt ur situation.
I used pcm-u and pcm-a codecs.
Hi All,
I just ported linphone to my arm board, and
call it from PC (ubuntu), and found a strange issue:
1) Directly call from PC, No sound.
Audio Streaming: Micphone(ARM BOARD) -->
ALSA(ARM BOARD) --> Linphone(ARM BOARD) --> Linphone (PC)
-->Earphone(PC).
2) In ARM BOARD, Use command "soundcard use
files", and then play a wav file, I can hear sound on earphone of PC.
Audio Streaming: Wav file(ARM BOARD) ->
Linphone(ARM BOARD) --> Linphone (PC) --> Earphone(PC)
3) In PC, use command "soundcard use files"
and then record a wav file. after end call, I can hear sound from wav
file, this sound is really from Micphone of ARM BOARD.
Audio Streaming: Micphone(ARM BOARD) -->
ALSA(ARM BOARD) -> Linphone(ARM BOARD) --> Linphone (PC) -->
Record to a wav file.
and use wireshark to capture these voip call
sessions,
In case 1), have rtp packets from ARM board,
but no sound In RTP Player of wireshark.
In case 3), have rtp packets from ARM board,
and found sound in RTP Player of wireshark. But I found that, Drop by
Jitter Buff is hight to 24.2%.
Anyone can help me? Any tips? Thanks!
Alex
