Thanks for the response.

No "allow=all" anywhere.  You got me thinking though, and it appears
that * has a nasty little parsing problem or something:

Here's my iax.conf

---begin---

[general]
port=4569
disallow=all
allow=gsm

[guest]
type=user
context=incoming

; Asterlink
[1234567]
context=incoming
type=user
disallow=all
allow=g726

---end---

It turns out that it's the Asterlink/[1234567] section that throws it
all off.  If I add an "allow=gsm" below "allow=g726", all is happy.  If
I don't, it fails.  

If I move the [guest] section below the [1234567] section, it works
again.

Very odd, I can't quite put my finger on what exactly is causing the
problem.  At least I have a workaround - I just need to shuffle things
around

Thx
