Abstract: A number of VoIP audio codecs generate Silence Insertion Descriptor (SID) frames during talk-gaps of conversations to update the comfort noise generator-parameters at the receiver. According to the RFC 3551 packetization scheme, discontinuously-generated SID frames can not be carried in the same IP packet, thus increasing the conversation’s bandwidth consumption.. We define a novel packetization scheme in which a set of non-consecutive SID frames may share the same packet, reducing the overhead while keeping the timing between them. We provide analytical expressions and experimental validation for the bandwidth savings obtained with this new scheme, which grows up to a 14% for the G.729B codec.
