<div>I have played a bit more with this and found in
config.yml:</div>
<div><br>
</div>
<div> sdp_line_filter:<br>
enable: yes<br>
remove_line_startswith: [b]<br>

<div> (I added the yes and the b)</div>

<div>This indeed filters out that line - sngrep shows that the
lb does not pass it to the proxy. However, the behaviour
remains the same. When a call comes in with a ptime of 60,
sipwise sends it on to the peer with a ptime of 40. My guess
is that it picks 40 based on the max bandwidth of 80? I had
hoped that by filtering that line from the sdp it would not
do this anymore but no joy there.</div>
<div><br>
</div>
<div>Any ideas?<br>

<div>Ok I am not entirely correct. It does seem to work
- but not to one carrier. The difference is that this
carrier responds with b=AS:80. As a result (and I am
only assuming it is as a result of that flag) the
packet size we are sending out is 40 which results in
one way audio. This is despite the fact that have set
the ptime to 20 and despite the fact that there is a
maxptime:20 in their response.<br>

<div>Hi</div>
<div><br>
</div>
<div>As part of our testing of MR6.4.1 we are
playing with repackatisation. We have set, on a
peer level, a packet size of 20. Then we send a
call from a PBX with a ptime of 60. I had
expected this to be repacketised to 20 going
upstream but that does not seem to work. <br>
</div>
<div><br>
</div>
<div>Am I misunderstanding this or is something
not working?</div>
