Have anybody test it on iPhone OS 4? Sound is not clear on other end, it is
like robotic voice. i am testing it on 3G device updated to OS 4.0.

Do you have this issue with siphon on cydia or did you compile by yourself 
Siphon ?

Compile by myself, i tested with pjSip 1.5 and 1.0-rc2. Both has same problem.
Same build works properly on old iPhone OS.

I observed the same problem on both 3G and 3GS. Any ideas?

This is due to old audio implementation, try audio driver using audio_dev

This error cause by the iOS4 and iOS3 call recAQBufferCallback & 
playAQBufferCallback as different frequence. iOS3 is more often than iOS4,  so 
in iOS4, pjsip delaybuf need more buffer. To define the macro 
PJMEDIA_SOUND_BUFFER_COUNT  in your config_site.h should correct this problem, 
36 or 48 is tested for OK. 
 Further, as Apple SDK, to get low latency or control the audio more carefully,  Audio Unit SDK SHOULD be used,  but it seems too difficult for me.

I have defined PJMEDIA_SOUND_BUFFER_COUNT in config.h
But there is the same robotic voice. Has nebody solved this issue.

you need redefine the macro in config_site.h not in config.h

Thanks sanit.peng I tried redefining the MACRO in config_site.h and it solved 
the problem. No robotic voice anymore. 
The only problem I see now is a considerable delay of the incoming voice. 1-2 
seconds.
I tried both 36 y 48 with no difference. Do you have any idea why this could be 
happening?

Thanks!

Don't know if this is related with this macro, thats why Im asking you here and 
not in a different Issue, also didn't found this issue reported.

Can we deliberately change a recorded voice into a robot's voice this way? Or 
is there a way to fake it?

GoogleCodeExporter commented 9 years ago 
Its not a nice faked robotic voice, practically you cant hear anything without 
the MACRO and you define the MACRO in the pjsip which you have to compile 
before using it on you app, so I guess you can't use this Macro to deliberately 
chage it.

I don't know a way to fake it, I guess, as sanit.peng says, using Apple Audio 
Unit SDK whould give you enough control to fake it.

I'm using iphone 3GS, just apply patch 
http://code.google.com/p/siphon/downloads/detail?name=patch-audioqueue-dev-20100
312.txt&can=2&q= y works fine. 

But iphone 4 with iOS 4.1 the problem returns, the robot voice reappears.
