Same here. But it seems to be somewhat related with the hardware: the 7960 
looses about .5 seconds, and an old siemens optipoint 100 I have around 
looses up to 2 seconds. 

But there's no delay with the ATA186 (sip) and with the Pingtel Expressa. With 
the ATA I can hear the change in the background noise shortly before the 
beginning of the recording, which is probably the connection of the rtp 
stream.
