Just use a ring buffer to put the delay back to normal.

You'll need to try, but to have any chance of working, the following
conditions must be met:
1) No codec must be used in the echo path (maybe G.711 is OK)
2) There must not be any drift in the sampling clocks
3) There must not be any audio samples lost on the echo path
