Hi, i am using currenct git trunk for some SBC-tests. I use the SDP-Filter and -anonmization features SEMS in my SBC-Profile, e.g.: sdp_filter=whitelist sdpfilter_list=G722,pcma,pcmu,telephone-event sdp_anonymize=yes
I've noticed the following two things: - the generated SDP has two "a=sendrecv" lines?!? (it seems, some endpoints have trouble with this) - docs says, the SDP is regenerated; but SEMS passes through some "a="-lines, which are not required, e.g. "a=crypto:" or "a=nortpproxy:yes.". Is it wanted this way? My Incoming INVITE: ~~~~~~~~~~~~~~~~~~~ U 2012/01/18 15:51:42.760177 84.252.101.17:5060 -> 84.252.101.19:5060 INVITE sip:258@localhost SIP/2.0.
