I suggest you to print the message buffer here just to be sure. Use
xlog("$mb\n");<br>

</div>
<p style="font-family: Helvetica,Arial; font-size: 12px;
text-align: justify;">Check if the method of the message
matches the name. If name is a known method (invite, cancel,
ack, bye, options, info, update, register, message, subscribe,
notify, refer, prack), the function performs method ID testing
(integer comparison) instead of ignore case string comparison.</p>
<p style="font-family: Helvetica,Arial; font-size: 12px;
text-align: justify;">The 'name' can be a list of methods in
the form of 'method1|method2|...'. In this case, the function
returns true if the SIP message's method is one from the list.
IMPORTANT NOTE: in the list must be only methods defined in
OpenSIPS with ID (invite, cancel, ack, bye, options, info,
update, register, message, subscribe, notify, refer, prack,
publish; for more see:<a moz-do-not-send="true"

<p style="font-family: Helvetica,Arial; font-size: 12px;
text-align: justify;">If used for replies, the function tests
the value of method field from CSeq header.</p>

<p style="font-family: Helvetica,Arial; font-size: 12px;
text-align: justify;">The CSeq header above sure enough has
"INVITE" inside it. And the is_method filed is being used
from a reply (it shouldn't really matter though right? It
should match regardless).</p>

it does, and then between the two log messages stuff
