TCP registration UDP media

[CPav]

Hi all. Ive got a question regarding tcp and/or udp.
I want to test out using tcp to overcome some issues with iphone app issues when the app goes into backround mode.
So Ive opened tcp for sip on my firewall but have left the media ports 16384-32384 as udp.

Does this mean registration alone will take place via tcp but audio will still occur over udp?

yes that is what it means. your audio will still be udp. also the way to work with the iphones that we have found is writing a lua script that sends the iphone a push notification to wake it up out of background mode then when it registers , send the call to the phone. if it doesnt register within a time frame , put the call to VM. while the call is waiting, we put it in park and play a ring tone

Thanks, I know nothing about LUA scripts or how to park the call temporarily...could you share that with me please? Tx
