[Freeswitch-users] UUI related question

[Ron McLeod]

Sounds like Q.931 .

 

4.5.30 User-user

The purpose of the User-user information element is to convey information
between ISDN users.

This information is not interpreted by the network, but rather is carried
transparently and delivered to

the remote user(s).

 

The User-user information element is coded as shown in Figure 4-36 and Table
4-26. There are no

restrictions on content of the user information field.

 

In SETUP, ALERTING, CONNECT, DISCONNECT, RELEASE and RELEASE COMPLETE

messages, the User-user information element has a network dependent maximum
size of 35 or 131

octets. The evolution to a single maximum value is the long term objective;
the exact maximum

value is the subject of further study.

 

In USER INFORMATION messages sent in association with a circuit-mode
connection, the Useruser

information element has a network dependent maximum size of 35 or 131
octets. For USER

INFORMATION messages sent in a temporary or permanent user-user signalling
connection, the

user information field contained inside this information element has a
maximum size equal to the

maximum size of messages defined in clause 3, that is 260 octets.

 

NOTE - The User-user information element is transported transparently by an
ISDN between a call

originating entity, e.g. a calling user and the addressed entity, e.g. a
remote user or a high layer function

network node addressed by the call originating entity.

Can you give more information?  A link to an rfc or example of how it is
used in other products?

 

I assume you already looked for the info in the vars that are pre-set using
hte info app?  If it is in a custom header then you need to understand a)
the header name and b) how to retrieve custom headers (on the wiki).

 

FS is not a proxy so you'll have to test for the header, set a var, and copy
that var into the b leg.  But let's get more info first.
