asterisk users - Jan 2005 - IAXy Static... and other issues

Hey Everyone,

I recently purchased a few IAXy units for some testing, and have come 
across a some problems.

One of them can be provisioned but will not ring the connected 
telephone.  It also does not provide a dial tone when you pick up the 
phone.  When a call is made to the IAXy one of the green lights on the 
board goes from a solid on state, to a flashing state that coincides 
with the ringing that is heard on the telephone you are placing the call 
from.

I have mentioned this to Digium who said they would replace it, and have 
been waiting for over a week for them to issue an RMA for it (as I think 
this would mean that the FXS is faulty). 

The other one that is giving me problems has a different setup.  It is 
being used from an outside network in another state (I'm in PA they are 
in VA), it registers with the * server, and I can call it.  The 
telephone connected will ring, but when the user picks up they cannot 
hear me but I can hear them perfectly.  If the user tries to call out 
via the IAXy, they don't get a dial tone... all they get is static.  If 
they dial an extension (say to call me) the extension called will ring, 
but again I can hear them but they cannot hear me.  This is also true if 
they call or are called from another IAXy, which (I think...) is working 
correctly.  I have read that the static may be a power supply issue, 
although the current power supplies were provided by Digium.  Also have 
read that the one-way voice could be related to trunking, but both the 
IAXy and the * server are set to no.  And a third IAXy has been working 
with the same iax.conf settings (except for a different extension).

To put another fun spin on this... I have been able to connect to the 
same iax.conf settings using Firefly soft phones without any problems, 
but would like to be independent of a computer whenever possible.  I'm 
not sure if I have missed anything... port 4569 is opened on both the 
router connected to the * server, as well as the router the IAXy is 
connected to.  I have also opened DMZ's on both sides, as well as tried 
without opening any of the ports or DMZ's.... I'm stuck.

Anyone with any thoughts.... I would really appreciate any help.

Having owned one of these for several months, here's what I've learned.

If you don't have a power supply that is stable at 1200ma the IAXy
won't work. It kinda/sorta worked on a 1amp supply but it works more
consistently on a 1500ma (1.5A) supply. Symptoms of bad power supply:
noise, hoorible static at random moments, being perfectly connected
with ring (but not ringing phone), apparent total playing dead but
accepting provisioning, etc. Basic flaky behaviour has for the moment
been stopped by a new power supply.

Further, many older European phones will not ring on the regular
asterisk setup and this includes when connected to an IAXy. I have
several three year old Siemens cordless phones that will NOT ring on
the IAXy. They don't ring on asterisk either without using the 25hz
ring patch in wcfxs.c

Every once in a while, the IAXy is no longer online. Someone has
pinned this to bootp and not renewing DHCP properly. This is possible,
I am trying to *prove* it now. However, giving the IAXy a fixed
internal ip will be an easy fix.
