thanks for the heads-up about grandstream, but as i stated in the 
original message, i'm using xten lite softphones.   hopefully this is 
the approproriate forum for this question; i believe this is not an xten 
configuration issue because i can connect to a ser/rtproxy/nathelper 
server without problems and i can connect directly to a voicepulse 
account, which leads me to believe that this is an * configuration 
problem on my part.  less likely, i suppose, is the chance that * isn't 
as robust in handling nat than ser or whatever voicepulse is running.

given the configuration files that i posted in the original message, are 
there any changes that i should make?  certainly the asterisk faq makes 
the solution seems straighforward [1]:


"Most likely you have a SIP client behind NAT that is trying to 
communicate with Asterisk without having the "nat=yes" setting in place 
in sip.conf. Another cause for this could be related to a user device 
that has an sip entry but has been physically removed (switched off or 
LAN-disconnected)."

but as my original message showed, i do have nat=yes in my sip.conf and 
i don't believe the latter scenario is true.

any help is greatly appreciated.
