Hello,
I have done sip set debug peer 601 and below is the output I get, it keeps doing the retransmitting over and over again.
Hope this makes sense.
aaa.aaa.aaa.aaa is my client side external IP
nnn.nnn,nnn.nnn is my server side external IP
192.168.1.12 is my grandstream phone local ip
192.168.0.30 is the local ip of the freepbx
