HI All,
I was simulating a conference scenario with Sipp. The Switch sends me a
update message with following Information.
UPDATE sip:5...@148.147.171.54:64478;transport=tcp SIP/2.0

As Sipp is receiving the UPDATE successfully but While sending the 200OK for
UPDATE the SES does not process the 200OK as it wants that the 200OK which
sipp sends should contains
two separate via headers .
In my case i send 200OK which contains the following dump
SIP/2.0 200 OK
From: sip:5...@avaya.com <sip%3a5...@avaya.com>

My final approach which i used to send was followed the regular expression
path .
I have used two regular expression commands to separate two strings from
the Via : header
The Regular expression
=====================
1. <ereg regexp=" .[^,]+ " search_in="hdr" header="Via:" assign_to ="2"/>
2. <ereg regexp="\,([A-Z]{3}/2\.[0-9]/[A-Z]{3})" search_in="hdr"
header="Via:" assign_to ="3"/>
the variable $2 gets *sip/2.0/tcp 148.147.171.28:5060
;branch=z9hG4bK83138303530393F5334001b.0*
and the variable $3 gets *,SIP/2.0/TLS 148.147.171.28:6001
;psrrposn=1;received=148.147.171.28;branch=z9hG4bK809229ebbebdd1893497b5ad100
The problem is i was unable to erase the "," (comma) from the string which
is stored in the $3 .
the sample of 200OK is shown below after applying the regular expression :
============================================================
*SIP/2.0 200 OK

If somebody has any idea how to get the second string without "," . Please
advice .
Thanks
