Hi Daniel!
Thanks for clarifications - one question left. I want to log all
destinations of a forked call, but not only the R-URI of these SIP
messages, but also the addresses to which the messages are sent (the
received paramter), Maybe we can update the $ds variable to also show
the received parameter if available, e.g.:
destination set: $ds=Contact: sip:[EMAIL PROTECTED]:5060,
sip:[EMAIL PROTECTED]:8718 (received:publicIP:port)
regards

Looking at this issue, I am wondering if worth to add the
pseudovariables $dh and $dp for destination host and port ... Also I
am considering to change a bit the $du reference so when the dst_uri
is not set to point to request URI. Would be these changes usefully?
Hi Daniel!
This reveals another question: What is the difference between: request
URI, first branch, all branches, destionation sets .....
I used xlog to log all this pseude variables just before t_relay.
first branch: $br=sip:[EMAIL PROTECTED]:8718
all branches: $bR=sip:[EMAIL PROTECTED]:8718
destination set: $ds=Contact: sip:[EMAIL PROTECTED]:5060,
sip:[EMAIL PROTECTED]:8718
destination uri: $du=<null>
request uri: $ru=sip:[EMAIL PROTECTED]:5060
In the above call scenario, there is just lookup() which reveals 2
contacts, one with public IP and one with NATed IP (received structure
used).
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 ( ;-) )
- Why does the destination set contains the NATed IP instead of the
received-IP?
Because many SIP UA clients drop the requests that have in R-URI a
foreign address (not the local one on which it listens)
- Why does all branches only shows the first one?
In your case, you have just one.
- Why is the request URI different to the first branch?
That's how ser was designed, the branch is set only in case of forking.
Daniel
