Greg,
the email exchange was too fast for me -- is there any open issue now
for which snom does not claim responsibility and the burden is on us?

I copied a few SNOM phone messages to the list.
I am having problems communicating with the
SNOM phone.
I guess it isn't working because the SNOM phone
sends a PRACK after the 183, and the received
OK doesn't have a 'Record-Route'. This doesn't make
sense to me. I don't know why the phone is listening
to the first OK (the OK to the PRACK) rather than the
second OK (the OK to the INVITE).
If that is the way it is then do I have the PROXY mis-configured?

if(method=="INVITE" | method=="BYE" |
method=="PRACK")
{
log(1,"TRACE: addRecordRoute()");
setflag(1);
setflag(2);
addRecordRoute();
};
append_hf("P-hint: ATEND\r\n");
if(!t_relay())
{
sl_reply_error();
break;
};
When I do a ngrep trace, I see the packet being relayed...

There is a Record-route going out, but not one coming back.
Does a Record-route need to be injected into the last
OK back to the UA?
This is too hard :-)
