Yes, we have verified that the configs lack the append_branch you mention. The fix has been done (https://siprouter.onsip.org/trac/changeset/15) and new configs are available through the regular downloads at onsip.org.
To your other problem: No clue, Aisling. Sounds very strange indeed. The config should only trigger proxy authentication on an INVITE (not REGISTER). Maybe what you are experiencing is Messenger sending a new INVITE. (It should not, as it should receive a 100 Trying from ser). Only a *complete* ngrep trace will help in understanding what's happening (and any error messages in /var/log/messages with the timestamp for matching) g-)

Hi,
I am testing the call forwarding features demonstrated in Issue 5 of the onsip getting started document. I found that blind call transfer worked perfectly but fwdbusy & fwdnoanswer gave me errors:
ERROR: t_forward_nonack: non branched for forwarding ERROR: w_t_relay(failure mode): forwarding failed ERROR: sl_reply_error used: I'm terribly sorry, server error occurred.
On the onsip site I noted that someone else had this problem and it was solved by putting append_branch in the fwdbusy and fwdnoanswer sections in the failure route.
Thankfully that fixed those errors. However when I went to test fwdbusy again, it doesn't give any errors but still doesn't work. The call scenario was as follows:
Windows Messenger client 3500 ring BT100 2092. 2092 is off the hook (thereby sending a 486 busy message) and the call should be forwarded to xlite client 5000.
i.e. 3500 -> 2092(busy) -> 5000
The message sequence showed that everything was correct up to 2092 sending the 486 busy to SER and then SER sending an ACK back to 2092. But then SER sends a 407 proxy authentication required to 3500 which replies with an ACK....and that's it...
Can someone explain why SER would send a 407 Proxy authentication to the original caller?...I thought this should only be in response to a register message?....
Any help appreciated, Thanks, Aisling.
