Hello,
I don't know if there is a simpler way, but if I had to do it, i would
try something like this (not tested):
<recv request="INVITE" crlf="true">
<action>
<assignstr assign_to="notify_slot" value="ok" />
<ereg regexp="NOTIFY" search_in="hdr" header="Allow:"
assign_to="notify_slot" check_it="false" />
<ereg regexp="ok" search_in="var" variable="notify_slot"
assign_to="notify_slot" check_it="true" />
</action>
</recv>
Rationale:
We set variable notify_slot to "ok" then we try to match the "NOTIFY"
in the header Allow.
If the match succeeds, notify_slot will be modified to contain
"NOTIFY". If "NOTIFY" is not found, then notify_slot will stay the
same.
So we just have to run a ereg against notify_slot and if it doesn't
contain "ok" the call will be marked as failed.
regards,
takeshi
