[Speex-dev] Operation with continuous tone

During hardware and network impairment testing, I sometimes just hold down a DTMF key to keep the audio busy. I have found that if I restart the receiver while the transmitter is still encoding DTMF, the receiver plays out a different tone, until the DTMF key goes off an on again.
Also, today I captured some Speex frames during a tone (but not including the start of the tone). When I later fed these into the decoder, I got mostly silence with some noise.
Is this behavior expected? I suspect it is, and I understand that this is not a real-world situation.
This testing was done with 1.2beta1, 8KHz, 8kbps, TI C55 DSP, no preprocessor or echo canceler.
