Hi Simon!
Please make a unified diff (cvs diff -u) and post it at the bugtracker on sourceforge: http://sourceforge.net/tracker/?group_id=139143&atid=743022
This way it can't get lost under thousands of emails.
regards klaus

after a quick check, the answer is : no
this is a quick hack i've made as a workaround. feedback welcome :)

Is this issue solved in Openser 1.1.0 ?
2006/7/7, Simon Morvan garphy@gmail.com:
As Daniel said on the ml thread :
it makes sense, we will analyze the implications and include it
on the
to-do list.
Cheers, Daniel
Has it been included in the developpement branch yet ?

I'm not sure about the maddr parameter. doesn't it mean that the
request
should be forwarded to this IP regardsless of the domain? If
yes, the
DNS lookup can be skipped.

hi i recently bounced into this problem, and i'm not sure here. i'm running the openser-devel, with the cacheless db_mode=3.
(works fine btw)
the record-route header received by the proxy on the other
side (SNOM4S), inserts
the domain name (iptel1.ipatl.se) and not the hostname
(sip.iptel1.ipatl.se) in the
record-route header, and uses the maddr=<ip_of_server> with
the actual server IP address.
now, when my client (behind the OpenSER) replies with an ACK
to the incomming OK,
it uses the Route-header recieved in the RR-header, and sends
the ACK to OpenSER. i
then get the following errors in OpenSER.
/usr/local/sbin/openser[3583]: ERROR: mk_proxy: could not
resolve hostname: "iptel1.ipatl.se"
/usr/local/sbin/openser[3583]: ERROR: uri2proxy: bad host name

the ACK i sent look like this:
Request-Line: ACK sip:2307@iptel1.ipatl.se;gruu=6fg9n6dl SIP/2.0 Via: SIP/2.0/UDP

as far as i understand, according the rfc 3263, the
route-header may contain domain name that
has to be resolved using SRV.
"6 Constructing SIP URIs
In many cases, an element needs to construct a SIP URI for
inclusion
in a Contact header in a REGISTER, or in a Record-Route
header in an
INVITE. According to RFC 3261 [1], these URIs have to have
the
property that they resolve to the specific element that
inserted
them. However, if they are constructed with just an IP
address, for
example:
sip:1.2.3.4
then should the element fail, there is no way to route the
request or
response through a backup.
SRV provides a way to fix this. Instead of using an IP
address, a
domain name that resolves to an SRV record can be used:
sip:server23.provider.com"
now, OpenSER only asks DNS for an A record of the name
recieved in the route header,
and since that's a domain name, it's unresolvable, and so the
ACK is never sent.
any hints or clues?
