<tt>Hi Pasan,<br>
<br>
That is really weird I would say. Could you "pack" the minimal
script to get this error (plus the pcap of the REGISTER) ? you can
send them off list to me.<br>

<div>I tried scrip_trace function and it also indicate same
behavior, I can see the value of $tu but it still gives the
error. Interesting thing is, it evaluates to true and invokes
the remove() function as well.<br>

Indeed, the logs show that the TO hdr is successfully

maybe it is not the $tu related ? try to activate the

It should be fine if $tu would translate

But I'm afraid you have something else
there, like another deeper error that
