<br>
I have two FS instances connected to each other over VPN. The VPN<br>
sometimes has poor connectivity and I was wondering whether<br>
jitterbuffer can help to improve the call quality. I am using the OPUS<br>
codec between the FS instances since it is supposed to behave better<br>
in lower bandwidth. The ATA on both ends are Linksys SPA3102.<br>
<br>
My connections is as follows:<br>
<br>
ATA_A---->FS_A---->vpn---->FS_B---->ATA_B<br>
<br>
<br>
When user A is calling to B where should i specify jitter buffer<br>
amongst the following:<br>
<br>
1. The bridge between Freeswitch instance FS_A and FS_B<br>
<action application="bridge"<br>
data="{jitterbuffer_msec=60}sofia/gateway/$1@FS_B_IP"/><br>
<br>
2. The bridge between Freeswitch instance FS_B and ATA_B<br>
<action application="bridge"<br>
data="{jitterbuffer_msec=60}sofia/internal/$1@ATA_B_IP"/><br>
<br>
Thanks,<br>
Rajil<br>
