Find the following line (if it exists) in your SIP profiles and set
it to false:<br>
<br>
<param name="inbound-zrtp-passthru" value="false"/><br>
<br>
This will allow transcoding to work, assuming that you also have the
appropriate codecs compiled, loaded and enabled. The companion
setting to this is:<br>
<br>
<param name="inbound-late-negotiation" value="true"/><br>
<br>
Which will first attempt to find a matching codec between the two
endpoints, and fall back to transcoding if a match cannot be found.<br>
<br>
Obviously, G729 will only transcode if you have a license for each
channel, but if I understand your question correctly, that's what
you're trying to work around. Ideally, the phones should offer a
list of codecs in order of preference, not just a single codec,
which is a good way to drop calls and irritate users.<br>
