This subject relates to a problem I am having, though likely it is
different.

I am using digium TDB40B connected to handsets, and I can't use the
flash/recall button on the phones. However, I can 'manually' do the
hook-flash.

>From memory (not good) I recall that in Australia the phones use a
shorter flash time, so I added the "rxflash" to my zapata.conf file. 

Using different values, I managed to get one of two possibilities:

1) Press flash, and the other party hears the DTMF tone. No Transfer.

2) Press flash, the other party is dis-connected (hears busy/congestion
tone) and you get a new dial-tone. As if you had hung up for a few
seconds, and then picked up to make a new call.

(1) happened if rxflash was higher than about 103, while (2) happened
with any number less than that.

I recall there being a number of parameters that need changing to make
this work, including reducing the pulse dial time, etc. However, I
haven't been able to find this in google/wiki.

Does someone perhaps know the magical answer to this?

Thanks,
Adam
