Hi Carsten,

Hi,
i just added a few lines to the SDP-Filter of the SBC in order to
clear "s=" and "o=" lines.
The "o=" lines is replaced with "-" as a user (per RFC2327: "or it is
"-" if the originating host does not support the concept of user
thanks, makes sense (but possibly it would also make sense to have
this configurable).
ids."), the sessionId and Version is replaced with new values.
caution here, this will break quite a few things. if you replace
sessionId, you will need to save the value and use it on every further
SDP that you send out (insteda of using a random one every time). The
Version needs to be increased if the SDP is not equal to the previous one.
so, if you want to do this properly, you need to add a little work here.

The "s="-lines is replaced with an empty string.
Some CPE's place the originating number in those lines of the SDP
(e.g. Zyxel-Devices), some Gateways add information here about the
gateway (e.g. Cisco or the Sipgate-Gateways).... regulations in
germany require that we anonymize messages; if the number stays in the
SDP all the anonymizing of the SIP-signalling is useless....
Thanks for a great SEMS!
So long,
Carsten
P.S.: Is iptel.org down or is it only not reachable from the Telefonica-Network?
there were some temporary issues with DB and tcp, but they should be
resolved. is it still not working?
