[e2e] question about the iLBC (VoIP)

To examine the quality of VoIP, E-Model is often used. The output of the
E-model is a transmission ration factor R: R=R0-Is-Id-Ie+A, where R0
represents the basic signal-to-noise ration, Is represents the
impairments occurring simultaneously with the voice signal, Id
represents the impairments caused by delay, and Ie represents the
impairments caused by codecs. 

Is there any publication gives the Ie value for the codec iLBC?
