[cisco-voip] UCM 9.1 SIP Normalization Rules

[Matt Slaga (AM)]

The port number is actually something entirely different.  In this case, I have 70 SIP trunks between UCM and Lync for a global egress point access (CSS different for each SIP trunk).  The ports are actually in the 5020-5050 range.

UCM puts this request in the SIP Start Line (Invite) with 5060 regardless of what the SIP trunk uses.

Everything works fine if the user is part of the Lync pool that is associated with the Mediation server.  If they are on a different pool, this port of 5060 (not talking transport here, just SIP message adjustment) causes Lync to drop the invite.  When this port reads 5061 in the SIP invite, the calls flow properly.

I’m attempting to apply a SIP Normalization rule to make a port adjustment on SIP calls between UCM and Lync 2013.


In the header, UCM sends the port number as 5060.  Lync has problems digesting this when referring the call to another pool and wants to see the header at 5061.


The script we are attempting to use is below.  It has been applied to the various SIP trunks between UCM and Lync.


When reviewing traces, the port is not being adjusted.  Either the LUA script is wrong below, or for some reason it is not being applied.


Any thoughts?




M = {}
function M.outbound_INVITE(msg)
local method, ruri, ver = msg:getRequestLine()
local uri = string.gsub(ruri, "5060", "5061")
msg:setRequestUri(uri)
end
return M
