customising outgoing SIP header using composer

[kiran.aaa@gmail.com]

Hello I need assistance with adding custom SIP header in outgoing SIP message from GVP.

Call flow is, GVP to AVAYA CM through Genesys SIP server.
GVP--->Genesys SIP server-->Avaya CM (SIP enabled)

Im developing callflow in Genesys composer 8.1, need to understand how to add custom header to outgoing SIP message when call is transferred using TRANSFER tag

Basically, I need to send the VDN information in UUI data field of SIP header as shown below

User-to-User: VDN=<7 Digit Number>;AccountNumber=<10 digit number>
X-GENESYS-AccountNumber: <10 digit number>
X-GENESYS-VDN: <7 digit number>

Thanks..

X-Genesys are attached data, so try as it, UDATA

If you mean pass these data from GVP to the SIP via transfer block, so just use the namelist parameter within transfer and fill the variable name which will be added to the SIP message

Just to refine Kiran's question:
In order to get the below SIP header, how should program in composer to get the same and what are the setting in SIP/MCP to be made sure? below 1234567890abcdef has to be passed to avaya session manager.

Refer-To: <sip:1234@10.0.0.1:5060?User-to-
User=1234567890abcdef%3Bencoding%3Dhex%3Bpurpose%3Disdnnetwork%
3Bcontent%3Disdn-uui>
SIP Server includes this in the INVITE request:
INVITE sip:1234@10.0.0.1:5060 …
…
....
User-to-User: 1234567890abcdef;encoding=hex;purpose=isdnnetwork;
content=isnd-uui

Genesys will always use the prefix Genesys-X or whatever is defined on the SIP Server as prefix
