Jiri,
I am aware of the reason why private Contacts make no sense. What was confusing me is that, in the record-route-header, my PRIVATE ip-address is quoted (not my dialup address) as shown in the ngrep-dump I attached. That's why I was interested in the config you are using at iptel.org. You are saying that there is no such one for 8.11 - what about 8.10? Is this still available?
regards, felix

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?
There is no such 8.11 iptel config file available.
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.
I hope that's easy to explain. We deny requests with private-IP addresses in their contact header field. Such requests can't be followed up by subsequent requests -- private IP addresses maky subsequent conversation non-routable. We better deny and tell you it would break rather than let it break later.
We except cases in which record-route was applied as we assume that record-routing is used in a smart way to get subsequent requests over NATs.
The only way the two requests differ is that the one using the outbound proxy uses a record-route
That's exactly the point.
