Hi gentlemen!
I use openser-1.2.2 and I want to access to dp & dP variables but
sometimes they are empty. I try to access it before and after t_relay()
and result is the same -- variable is empty.
When this variables are set?
Manually in openser.cfg or by some functions (e.g. lookup() or
loose_route()).
Is it possible that they are not set at all?
yes.
If openser forwards the request (e.g. t_relay) it verifies if DURI is
set. If yes, the request is sent to the DURI.
If DURI is not sent, the request is forwarded to the RURI.
a typical example: client behind NAT register with Contact URI
sip:192.168.2.2:5060. The request comes from 1.2.3.4:8888.
Then during save openser will save the contact and the public address.
Further, if you lookup() this user, the lookup function will set RURI
to sip:192.168.2.2:5060 and duri to sip:1.2.3.4:8888
