Thanks Daniel.
I found your posting four years ago about saving one contact per user
http://lists.kamailio.org/pipermail/devel/2008-October/016273.html
and used save("location", "0x04"). However, I noticed a problem with this.
The contact is not storing in the memory. Whenever there is a
Reregistration
happening, the contact is briefly not available for routing.
Then I looked at the resgistrar code, I am befuddled.
-- code snippet:
/*! \brief
* Wrapper to save(location)
*/
static int w_save(struct sip_msg* _m, char* _d, char* _cflags)
{
return save(_m, (udomain_t*)_d, ((int)(unsigned long)_cflags));
}
The string "0x04" looks like getting type-casted to long.
this is so called fixup mechanism in SER/Kamailio. At startup the
parameters which come as char* from config are pre-compiled in various
forms (in this case is an integer). At runtime, the config interpreter
calls the function with the pre-compiled form of the parameter, thus the
cast.
Look for save_fixup() function to understand better. Also, the devel
guide on the net should have a section about this mechanism.
Cheers,
Daniel

Hello,
if you don't use the other contacts, then might be simpler to just
store one contact per AoR (which will be from last registration)
-- see save(...) second parameter flags.
Don't remember by hart, but registrar or usrloc has a parameter to
control whether to add or not additional branches from a location
lookup - check the readmeas, but I am not sure the first result is
the most recent, you would have to test it or check the sources.
The last coming in my mind right now would be to program it in
config via reg_fetch_contacts() and $ulc(...).
Cheers,
Daniel

Hi,
I am trying to relay the message to the Registered user. However,
I would like to relay only to a recent contact.
In case, there are multiple contact, I do not want to relay to
older contacts.
I am using t_relay() which is currently forking the request to
all contacts.
Any other way to accomplish my need?
Thanks
Krish Kura
