What model phone are you using?
Tried with iPhone SE and Nokia X3-02. Again, even failed with the 5-sec delayed echo test.
I've tried SIP-SIP calling using LinPhone (Windows) to LinPhone (iPhone) and that works with both-way voice. Here's my codecs in vars.xml
<X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=L16,99,G729,GSM@40i,PCMU,PCMA"/>
Thanks, Jeff
