asterisk users - Jun 2007 - problem with one way audio

I have a company with asterisk 1.2.19 and polycom 501 phones.  I get one way 
audio.  A caller from the pstn world hits the tdm400 card, This rings two 
phones in a ring group.  My client answers the phone, the calling party is 
told the customer here her but she can not here them. The customer hangs up 
and calls back and the call goes through..

I rolled back to 1.2.14 and the problem is much better but is still there,

Are there any ideas

Do you have CallProgress=yes in your zapata.conf?  This one just bit me 
in the arse this morning.  I set it to no and one-way audio went away.
