TCP Transport

I am trying to get a sip client working on my cell phone. Someone recommended trying tcp over udp. I have TCP Only set under the the extension settings in freepbx as well on the client but it wont register? Is there anywhere other settings i am missing? I have looked under Asterisk SiP settings and see nothing relavant to tcp?

Thanks

tcpenable=yes must be in the other sip settings regardless of what you set in extensions. I now have it working.

The fast way:

srv# cat >> /etc/asterisk/sip_custom.conf << EOF
tcpenable=yes
tcpbindaddr=0.0.0.0
EOF

srv# asterisk -x "sip reload"
