[Freeswitch-users] Phone not registering

[Miha]

Hi @Michael,

after I put

<param name="NDLB-force-rport" value="true"/>

in my internal sip profile FS send back to right dst_port.

If I use this on live fs server, could this be causing any problems on registered phones or any easier abuse?

Thanks!

Miha
