[cisco-voip] UCM 9.1 SIP Normalization Rules

[Matt Taber (mtaber)]

Hi Matt,

Cisco Developer Network (CDN) is available to support the design of LUA scripts utilized for SIP Normalization:
https://developer.cisco.com/site/devnet/support/

Information pertaining to SIP Transparency and Normalization scripting can be found in the following:

Matt,

Cisco TAC doesn't support SIP Normalization Scripts.  Developer support has to be used for things like this.

It’s the request line (INVITE sip:firstname.lastname at domain.com:5060 SIP/2.0


We attempted to open a TAC case on this issue, and I’ve never seen Cisco toss a hot potato that fast in my 15 years of dealing with them.  It’s like I clicked ‘send’ and got a reply back from an engineer saying ‘not supported’.  That’s the first I’ve seen a viable option with the CUCM interface rejected as not supported.

Hi matt,
which line are you trying to change? The To Field(TO:blabla at blabla.com:5060<http://TO:blabla@blabla.com:5060/> or the request Line (INVITE...)

thanks

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
