Hello all, I am trying to test a number of compression algorithms provided by pjproject but I seem to be getting a constant, erroneous "BAD GATEWAY" when trying to run pjsua on my target. The problem seems to be pj specific since my gateway is set up correctly in other applications and I have tested the command I am using on a number of other pjsip builds without error. With this in mind I now turn to the 'encdec' application to test general encoding/decoding, however, the only codec i can get to work is "gsm" since trying all other variants I get the following error: "pjmedia_codec_mgr_find_codecs_by_id(cm, pj_cstr(&tmp, codec_id), &cnt, &pci, NULL) error: Not found (PJ_ENOTFOUND)" With this in mind, can anybody provide some detailed information on the codec syntax? In particular, I wish to 'play' with the g711 - some sources indicate that this is not included but others specify the contrary - and the g.726 codecs which are included with the IPP codecs. Any help would be much appreciated. Best regards, Steven
