1. Use Opus
2.
3.
What is the expected output? What do you see instead?
with SILK I get OK sound, but with Opus the audio is choppy.
because of "Issue attachment storage quota exceeded", here's a link:

I wonder if my ZTE Blade III (cyanogenmod 11) is too slow. The other end has Nexus 5 (Lollipop).
If CPU is too slow, csipsimple should run performance test on startup.

Sounds like problems I had with compatibility of older version of Opus spec. Are both devices using the very latest opus plugin version? Also, is there a sip server in the middle?

Both devices have the latest codec pack from Play.
We both have configured ostel.co accounts, using tls and zrtp.

Hi,
The version on the playstore is outdate.
Please download and install the 1.5 from http://nightlies.csipsimple.com/plugins/
I'm trying to solve some change in android 5.x changes before releasing on playstore.

I'm experiencing another kind of choppy sound with Opus: with a ptime of 40ms in FreeSwitch (Opus frame composed of 2*20ms subframes), the decoded audio by CSS is missing the second part (20ms of sound followed by 20ms of silence) and so on...

I've been taking a look at opus_codec_parse() (pj_opus.c) and if I set *frame_cnt = 1; before the loop, the issue improves with continuous clicks.
By the way, in opus_codec_decode(),
the mask for frm_info should'n be 0xff, as shown in opus_codec_parse()?
frm_info = input->bit_info & 0xFF;
instead of
frm_info = input->bit_info & 0xF;
Opus accepts up to 48 subframes for an internal ptime of 2.5ms.
