Hi Fredrik! You can try SipGo (low bandwith), works fine with iPhone, Android, Symbian and Windowsphone together with FS.

I have both Android/IOS devices can you recommend any SIP client? ... I see Zoiper is available for both Android/IOS and Windows etc. OK, I will give it a try. Thanks.

There's a number of possibilities- incorrect mic levels, timing issues, no jitter buffer on FSClient, so external testing will help narrow it down. Zoiper communicator is good for this, as is Xlite and a few others. 3CX _might_ still work, if they haven't dumped the free SIP version yet? Better still, if you have a hardphone with current firmware, that's a better point of reference again.

I think it’s verision 1.5.7b, at least according to the output from fs_cli.exe. The installation is pure local on my own home LAN (100 mbit), i.e no VOIP gateways etc. I am playing around with the installation and the FSClient 1.2.3.5 as softphone calling the echo test, calling between extension 1000 – 1001, voice mail 4000 etc. Everything seems fine but the sound is somewhat distorted. The sound is a little/somewhat scratchy. I’ve tried to change codec in FreeSwitch and/or the FSClient but without luck. Since I am completely new to FreeSwitch I thought that I would ask the community about it. What might cause this sound distorsion? I have recorded the sound but I was not sure it I should attatch it or not. Any help is appreciated.
