So you need the B2B Logic ID only when you create the B2B session,
in order to place it in the first outgoing INVITE (as extra hdr),
right ?<br>

My bad - in Call-ID and TO tag you have the B2B
_entity_ ID, while you need the B2B _logic_ ID
.....which is not part of the signaling at all .<br>
<br>
Now, in script, where do you need the b2b logic ID
? after creating the B2B session (after b2b_init()
) ? Or ?<span><br>

<tt>Hi Ping,<br>
<br>
b2b_bridge_request() is a script
function:<br>
<a href="http://www.opensips.org/html/docs/modules/2.1.x/b2b_logic.html#id294094" target="_blank">http://www.opensips.org/html/docs/modules/2.1.x/b2b_logic.html#id294094</a><br>
<br>
I pointed to this function as you
mentioned (on my question) that
you want to do the bridging from
script level.<br>
<br>
Indeed, the equivalent MI function
is b2b_bridge:<br>
<a href="http://www.opensips.org/html/docs/modules/2.1.x/b2b_logic.html#id294210" target="_blank">http://www.opensips.org/html/docs/modules/2.1.x/b2b_logic.html#id294210</a><br>
<br>
If you want to get that </tt><tt>"1020.30",
you can get it from Call-ID or To
tag, where you have B2B.</tt><tt><tt>1020.30
(so you have to strip that B2B
prefix).<br>

It seems the function you
mentioned is the internal
function "1.4.2
b2b_bridge_request(b2bl_key,entity_no)".
<br>
<br>
Actually the function that I
am trying to use is the
"b2b_bridge" (Exported MI
Functions). It is defined as
below<br>
----------------------------------<br>
<a href="http://www.opensips.org/html/docs/modules/2.1.x/b2b_logic.html#id294210" target="_blank">http://www.opensips.org/html/docs/modules/2.1.x/b2b_logic.html#id294210</a><br>
<br>
<br>
1.5.2. b2b_bridge<br>
<br>
Example: opensipsctl
b2b_bridge 1020.30 <a href="mailto:sip:alice@opensips.org" target="_blank"></a><a href="mailto:sip:alice@opensips.org" target="_blank">sip:alice@opensips.org</a><br>
----------------------------------<br>
<br>
In the example "1020.30" is
the "dialog-id". This is the
parameter that I am not sure
how to easily access in the
Opensips config. <br>
<br>
What I am trying to do is to
get the value and deliver to
the next hop via a custom
SIP header. When the next
hop tries to transfer the
call to a new destination.
It can run the b2b_bridge
command straight away with
the "dialog-id" without
rechieving the value from
the Opensips database (from
b2b_logic or b2b_entities
tables).
<div><br>
</div>
<div>Any advice will be
appreciated.</div>

<div text="#000000" bgcolor="#FFFFFF"> <tt>Hi
Ping,<br>
<br>
In script, in a b2b
route, you can look
at the callid or TO
tag (depending on
the direction) to
get the key :<br>
<a href="http://www.opensips.org/html/docs/modules/2.2.x/b2b_logic.html#id294094" target="_blank"></a><a href="http://www.opensips.org/html/docs/modules/2.2.x/b2b_logic.html#id294094" target="_blank">http://www.opensips.org/html/docs/modules/2.2.x/b2b_logic.html#id294094</a><br>
<br>
The B2B uses that
key as Call-ID when
acting as UAC and as
To tag when acting
as UAS. You can run
a SIP capture to see
the traffic.<br>

Indeed, my bad
- the docs are
not updated,
as that param
was disabled
long time ago
(4 years ago):<br>
<a href="https://sourceforge.net/p/opensips/bugs/502/" target="_blank"></a><a href="https://sourceforge.net/p/opensips/bugs/502/" target="_blank">https://sourceforge.net/p/opensips/bugs/502/</a><br>

Still, there
are available

the question
is : do you
need that

OpenSIPS cfg
or outside
OpenSIPS ? as
there are
different way
to get the ID.<br>
