Hi, I think Zoiper 3 and later has different CODECS (iLBC20 and iLBC30) define, which differentiate the frame rate. See: https://www.zoiper.com/en/support/answer/for/windows/104/Codecs I have tested G.729, but found it to have lower audio quality than iLBC, to my ear, at least, with about the same bandwidth use. The patents which did encumber most G.729 implementations are now expired. I have also experimentally added CODEC2 / 3200bps. Other than being CPU heavy (as expected), it works fine, but sounds closer to DMR-quality audio than is typically desirable for most AllStar use...But, this CODEC is by far the low-bandwidth leader of the free CODECs I've tested. 73, David KB4FXC On Fri, 25 Aug 2017, Toussaint OTTAVI wrote:

Stock Asterisk uses 30ms iLBC audio frames, which can end up sounding like "Mr. Roboto" with AllStar, which strictly expects 20ms frames....These patches convert iLBC for Asterisk to 20ms frames, so it's compatible with AllStar.
Wow ! Thank you, I didn't see that ! I just compared file sizes, and saw they were identical. But I didn't see the content was different...
Also, note that is you use this patch in conjuction with SIP phones, softphones, etc., make sure they're set to 20ms frames, too.
Humm, another problem : my current software client (Zoiper for Android) does not allow to set timing value. Does someone know an IAX2 client for iPhone/Android which supports iLBC, and which allows to change timing value ? 73 de TK1BI _______________________________________________ App_rpt-users mailing list App_rpt-users@lists.allstarlink.org http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users To unsubscribe from this list please visit http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users and scroll down to the bottom of the page.
