[Freeswitch-users] Zoiper goes crazy with registrations RPORT bug?

[Bipin Patel]

Hi,

I use zoiper with freeswitch and tls+srtp and I don't have such an issue 
with rport other than the tls profile which keeps hanging with is another 
bug. Could you kindly provide the profile xml to which the clients are 
registering
