Hi!.
I have tested the voip softphone in raspberry pi.
Specific environment is, rpi B+, cirrus audio card, linphone(CLI).
Use the command 'aplay' has confirmed the sound recording and sound output.
But, voip client(linphonec) is not succeed.
1. The test was as follows:
1) Voip Test Environment
- IP PBX => 192.168.1.4
- rpi tel no. => 1001
- remote tel no. => 1000
- ~/.asoundrc =>
pcm.!default {
type hw
card sndrpiwsp
}
ctl.!default {
type hw
card sndrpiwsp
}
2) I run the 'linphonec' comes a warning message as shown below and voip registration is successful.
pi@raspberrypi:~$ linphonec <enter>

Ready

3) When I connect call, we get the following error message.

2. I do not know the meaning of these error messages.
(ortp-error-alsa_open_w, ortp-error-alsa_open_r)
What is the reason that voice input and output not running?
Thanks.
