Hi,
The iPhone client, when it goes into background, can only respond
to incoming messages.
That makes the Registration expire when there is no communication
from the server before
the expire time. I could make the Registration not expire at all.
Not sure it's the only option.
Is there a way to send a Ping message from server periodically to
the iPhone SIP client. This
will wakeup the SIP client and resend REGISTER message.
you can set the nat_bflag (see usrloc module) to mark the registration
as being natted. Then use nathelper module mark it to send OPTIONS ping
(sipping_bflag parameter).
