After upgrading to Lollipop the other party cannot hear me. Is there anything I can do to fix this?

Can confirm same problem on a Nexus 5 with Lollipop, the voice being sent from SipDroid is garbled. Incoming voice is decoded and played back fine, unless the other end is an exact duplicate setup when it will obviously sound garbled!

RTP packets are being sent ok, so presume it's something to do with microphone capture, buffering, gain etc. A fix would be much appreciated.

Issue 1156 has been merged into this issue.

Since I have no Android L device I can't fix it. The Samsung 10.1 2014 that I have will be updated in March 2015.

What you could try is if voice is transmitted in speakerphone, or in bluetooth modes.

A logcat trace might also be helpful. Any other ideas?

brother pmerl, any update on this issue since you have got the lolipop update

I installed CM12 on my Samsung Note 10.1 (2014). Sipdroid worked fine. So it's not a general Lollipop incompatibility. Instead it must be related to specific devices.

Is it just the Nexus 5? Then I should get such a device to test.

read Issue 1156 this is an ART runtime issue. As with the devices listed there are not running lollipop and if they switch to dalvik runtime everything works, but when they use the ART runtime things stop working. The reason why lollipop is looked at is because it runs ART runtime by default

The issue with ART was fixed in Sipdroid 3.6 (Dec 2014). Actually I've tested Sipdroid on my Samsug tablet with AOSP Android 5.1 which should be always on ART.

In Android Playstore there are complaints about Sipdroid not running properly on HTC and Nexus 4/5/7 devices, but there is nobody mentioning incompatibilities to Samsung.
