Dear All , Errors disappear when just setting MDA=1 in symbian_ua_gui.mmp file as following // The part below will be overwritten by automated test // =BEGIN #define SND_HAS_APS 0 #define SND_HAS_VAS 1 #define SND_HAS_MDA 1 // =END Although still all needed to activate VAS direct applied . Does this make any sense to activate both VAS and MDA ? Also after signing the sis file and testing it on Nokia RDA E63 I found an unexpected SDP media offer received by our C4 SSW facilities indicating that my SW-Codec on/off settings in my config_site file have been totally ignored o=- 3540324523 3540324523 IN IP4 80.186.251.24 s=pjmedia c=IN IP4 80.186.251.24 t=0 0 a=X-nat:0 m=audio 4002 RTP/AVP 97 3 0 8 96 a=rtcp:4003 IN IP4 80.186.251.24 a=rtpmap:97 speex/8000 a=rtpmap:3 GSM/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:8 PCMA/8000 a=sendrecv a=rtpmap:96 telephone-event/8000 a=fmtp:96 0-15 -------------- next part -------------- An HTML attachment was scrubbed...
