asterisk users - Jan 2005 - Clipping on outbound calls via SIP/IAX

I'm hoping someone can help me with a problem I've been having for a
while
now. I've googled and wiki'd to no avail. 

Whenever I place an outbound call from * to a PSTN through a SIP or IAX
provider (e.g. Voicepulse or Broadvoice), the first 1/2 to 2 seconds of the
remote call are clipped (muted). For example, if I call a remote voicemail
system that usually answers with "Nortel Call Pilot, Mailbox?" I might
get
"ilot, Mailbox?". Everything works fine if I dial an internal
extension or
through the PSTN. Is this just something I'm going to have to live with if
using an Internet-based termination provider? I'm using Asterisk 1.0.3 and
have tested on different systems, different providers, different phones, etc.

Thank you,

I have the same symptom, dialing from a phone hanging off a iaxy that 
talks to my * and then outbound through NuFone. Where I expect to hear 
"Thank you for calling foo..." I get "calling foo..." only.
