I understand how you'd prefer to deal with an exclusion set in sipXbridge, but that sounds like an implementation detail. The admin should see simply a list of codecs that can be selected and de-selected. I would suggest using the new Codec Preferences selection GUI control. For those that haven't seen XX-5492 yet, check it out here: http://track.sipfoundry.org/secure/attachment/20664/New_Polycom_Codec_Se lection.JPG.jpg This is great stuff! By default a new SIP Trunk should have all known codecs selected, and therefore an empty exclusion set. -Paul [email protected] _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
