Can you please describe the difference of these
variables?
- a branch is an address other than R-URI that should replace R-URI in
the message in case of parallel or serial forking
- all branches pseudo-variables is a comma separated list of the
branches set for the message
- destination set is the list of all addresses that will be set as R-URI
for the SIP message (case of serial or parallel forking). This includes
the R-URI and branches.
- destination uri is the address where the message is to be sent (the
outbound proxy, next hop -- if it is not set, then the message is sent
based on R-URI address). Note that for each branch you can have a uri to
put as R-URI and an address as dst_uri
- request uri is the address in the first line of a SIP request, after
the SIP method ( ;-) )
That brings on another question, what does avp_write($ruri,"i:100")
use after lookup? dst-uri or branches?
