The biggest problem for supporting SIP based VoIP on android is the capability of the android media framework.
As for example, if you refer to this table: http://developer.android.com/guide/appendix/media-formats.html..most of the media encoders are not present. There is no use for having only a decoder for codecs, as in a SIP based VoIP session, you will need both the encoder and the decoder for bidirectional "SENDRECV" streaming of media. Most SIP clients use SDP as a means of codec negotiation. Going by that table, we can only use AMR-NB for voice and H.263 for video in the SDP offer for a SIP based session. As a workaround, sipdroid uses its own G.711 and H.264 codec by making use of a native library and JNI calls. For SIP/VoIP, playing from a static resource on the device is hardly a requirement.
