Hi Eric,
You could store the RSeq and CSeq in the 1xx response as variables and reuse it
in the PRACK:
<recv response="180">
<action>
<ereg regexp=".*"
search_in="hdr"
header="RSeq:"
assign_to="1"/>
<ereg regexp=".*"
search_in="hdr"
header="CSeq:"
assign_to="2"/>
</action>
</recv>
<send>

"Liangyou Wang (liangwan)" <[EMAIL PROTECTED]> 說: Hi All,
Now I am trying to construct PRACK message as the following:
PRACK sip:[EMAIL PROTECTED]:5060 SIP/2.0
Via:SIP/2.0/UDP
10.21.50.6;branch=z9hG4bK-BroadWorks.10.21.50.6-10.19.5.1V5060-0-3257122
72-1456418016-1181767430940-
From:"Not
Known";tag=1456418016-118176743094
0-
To:;tag=1838537778
Call-ID:[EMAIL PROTECTED]
CSeq:325712272 PRACK
RAck:2 325712271 INVITE
Max-Forwards:10
Content-Length:0
But it's difficult to define RAck!!! "RAck: 1 [cseq]" is not right! Who
can help me?
Thank you!
Best regards,
Eric
