iLBC is the first codec ever to be standardized by the IETF (RFC3951 and RFC3952) and is designated by CableLabs as a mandatory component of PacketCable voice-over-cable telephony systems.
Other standard low bit rate codecs make use of dependencies between speech frames, resulting in error proliferation when packets are lost or delayed. In contrast, iLBC encoded speech frames are independent. This unique technology gives iLBC robustness against packet loss and delay.
Royalty-free with speech quality better than G.729A and G.723.1.
Better packet loss robustness compared to other low-bit rate codecs, including G.729A, G.729E, G.723.1 and G.728
iLBC supports multiple frame sizes giving increased flexibility to meet the needs of different applications and/or VoIP equipment
iLBC delivers the same basic quality as G.729E and exceeds G.729E under packet loss conditions
Can be used with data frame length of either 20 milliseconds or 30 milliseconds
Supported by ARM processor-based devices
