Hello, o Carsten Bock on 08/04/2011 12:22 PM:
Hi,short question: In the codecfilter.sbcprofile.conf-Example it says the following: # sdp_filter can be transparent,whitelist or blacklist # - leave empty (commented) for no touching SDP # - transparent does SDP reconstruction ('sanity check') # - whitelist and blacklist filter codec on both sides If set to transparent or whitelisting, is the SDP really re-constructed? I've noticed, that the session-name (s=) is passed
now it is.
through as well as the "o="-lines. What about other attributes? I wonder, if a gateway sends me buggy "a=silenceSupp:off - - - -" lines, is it passed through as well? I
incomplete a=silenceSupp lines are now fixed with [master 2618b89] SBC: fixing incomplete silenceSupp media attrib if you are using 1.4, you should be able to cherry-pick without problems. Stefan
know some Cisco-Gateways will not connect that call, if the "a=silenceSupp:off" is incorrect according to the standards. By the way: Is there an easy way to add a "own" music-on-hold announcement, if a call through the SBC is put on hold?
