Hello,
I remember having read somewhere that the 'ser.cfg' file used at
'iptel.org' can be downloaded somewhere in order to be used as an
example for many of the functionalities ser offers. Unfortunately I
can't remember where I read this, nor did I find it on the ftp server...
:(
Is this config file still available for download?
No, unfortunately it is not available anymore.
I am mainly asking because I am looking for an answer
for the following
phenomenon:
I have SER running on my home network (on the gateway). When I try to
send an IM to my account at
iptel.org using kphone and I use my gateway
SER as an outbound proxy, everything runs smoothly; I get a message back
from
iptel.org that the IM will be delivered to me as soon as I login
the next time (what will not happen until I solved the NAT problem ;)).
Now, when I try the same without using my gateway as an outbound proxy,
I get the beloved message from
iptel.org that it doesn't like my private
Contact address.
The only way the two requests differ is that the one using the outbound
proxy uses a record-route
This is a bug in our configuration because Contact header field
shouldn't be checked in MESSAGEs. We will fix it, thanks.
And now why you get different response when you use a record-routing
proxy.
If a SIP messages contains Record-Route header field then we
do not check what is in the Contact, because the server will not use
the header field anyway. Further messages will be sent to the URI in
the Record-Route. Inserting a private IP into Contact is perfectly
legal in this case because the record routing proxy might be in a
private address space and probably knows how to route such requests.
If there is no Record-Route then our proxy uses Contact to route
further requests and thus it check if the URI in the Contact is
reachable.
