Any chance the devices performed a codec re-negotiation when swapped over?

I've seen (or heard) somethng very similar (although using Asterisk) when:

 - answering a call (audio is perfect)
 - placing the caller on hold (hold music is fine)
 - resuming the call (audio is essentially incomprehensible)

note: no change in devices at all.

It turned out that the "resume" after hold was re-negotiating the codec in the 
SDP.
