Is it possible to allow an UA to make calls
without it registering itself?
yes.
Can SER extract the contact info from the
INVITE and then upon detecting that the "user is not
registered" simply register the contact info?
you could write a module function to do that, but it would not be a good
idea, because re-registration would require a new call before the
contact expires.
Maybe Im wrong.. and Im not sure if this scenario is valid.
In some cases, you have expires on a register for ~60 min.And keep
NAt'ed openings open with some form of nat-keepalive (notify, options
whatever).
The scenario is :
user looses dsl link and gets a new ip when it coms up again, phone is registerd, and user
can call out, but are
in this case not able call-in, it's 30 min until new register is issued.
Or User looses dsl link, user is offline when registrations should be
sent.. after a few retries, Ua backsoff to not kill server when it coms
up again. User dials out.. this works, but now, since UA has backed off, It will not issue
a new registration for X sec.
In these to cases, I think a function as described above would be cool,
but I dont know how it would be security-wise etc.
