[SR-Users] TLS connection with short lifetime - how to handle it?

I have the next problem:
iOS based clients connect via TLS to kamailio server.
They run mostly in background mode - it means connection refresh interval
is ~10 minutes.
Some of clients reside behind paranoidal routers which considers such idle
connections as lost and closes them.
I see only way to resolve it is to send OPTIONS/NOTIFY/CRLF from kamailio
Tried to use nat_traversal module by calling nat_keepalive() to every
REGISTER message. But there is no incoming keepalive (OPTIONS or NOTIFY) on
Is there another way to make "heartbeat" in SIP/TLS from server side?
