Hi Ping,<br>
<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 ?<br>
<br>

<div>I have done a few testing. It seems only the value of the
param works for this function. However, it does not look like
the callid and the to-tag. </div>
<div>Is it possible to get the param value in the Opensips

<div text="#000000" bgcolor="#FFFFFF"> <tt>Hi Ping,<br>
<br>
b2b_bridge_request() is a script function:<br>
<a moz-do-not-send="true"
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 moz-do-not-send="true"
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 moz-do-not-send="true"
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
moz-do-not-send="true"
href="mailto:sip:alice@opensips.org"
target="_blank"><a class="moz-txt-link-abbreviated" href="mailto:sip:alice@opensips.org">sip:alice@opensips.org</a></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>

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 moz-do-not-send="true"
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>
<br>

I need the value in the Opensips

I understand that I can query the

Apart from that could you tell me
other way to easily access the value

Indeed, my bad - the docs
are not updated, as that
param was disabled long time
ago (4 years ago):<br>
<a
moz-do-not-send="true"
href="https://sourceforge.net/p/opensips/bugs/502/"
target="_blank"><a class="moz-txt-link-freetext" href="https://sourceforge.net/p/opensips/bugs/502/">https://sourceforge.net/p/opensips/bugs/502/</a></a><br>
<br>
Still, there are available
option. But the question is
: do you need that value in
OpenSIPS cfg or outside
OpenSIPS ? as there are
different way to get the ID.<br>
