<span style="font-family:verdana,sans-serif">Hi All,</span><br style="font-family:verdana,sans-serif"><br style="font-family:verdana,sans-serif"><div style="margin-left:40px;font-family:verdana,sans-serif">We`ve
been using freeswitch since very long, It was good all over but it got
stuck to a simple yet complex situation. We have Yealink T28P series
phones behind NAT and freeswitch is unable to get them register. In the
scenario freeswitch is at public IP. The reason we think is that
freeswitch is using sip port in contact header to respond to.<br>
<br>Is there anyway we can avoid this or force it to always send the
response to destination IP instead of contact or via header ports
because clients are behind NAT and response can only reach them if it
respond to destination IP & PORT.<br>
<br>Please revert if someone know how to solve this problem. It is very urgent.<br></div><br style="font-family:verdana,sans-serif"><span style="font-family:verdana,sans-serif">Regards</span>
