So does it make sense at all to switch it on for HFC-S controller used in NT-Mode with ISDN-Phones connected?

I have echo training set on in my zapata.conf file for a X101P card: echocancel = yes echocancelwhenbridged = yes echotraining = yes
Now, I know that echo cancellation is a black art, but I am finding that at the beginning of a call bridged between a SIP channel and a Zap channel the voice quality is poor to abysmal for the first few seconds, but as the call progresses, esp after about 30 seconds, the call quality becomes very acceptable.
Should echo training take that long? Is it, in fact, echo training or some thing else? Has any one got any guidance on ET other than what is in the wiki, which I find to be very hard to follow?
Try echotraining=800 and see if that makes a difference.
