Hi Ping,
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 .
Now, in script, where do you need the b2b logic ID ? after creating the
B2B session (after b2b_init() ) ? Or ?

Thanks, Bogdan,
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.
Is it possible to get the param value in the Opensips config?
Please see the test results below.

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

Thanks, Bogdan,
It seems the function you mentioned is the internal function
"1.4.2 b2b_bridge_request(b2bl_key,entity_no)".
Actually the function that I am trying to use is the "b2b_bridge"
(Exported MI Functions). It is defined as below
----------------------------------
http://www.opensips.org/html/docs/modules/2.1.x/b2b_logic.html#id294210
1.5.2. b2b_bridge
Example: opensipsctl b2b_bridge 1020.30 sip:[email protected]
<mailto:sip:[email protected]>
----------------------------------
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.
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).
Any advice will be appreciated.
Thanks,
Ping

Hi Ping,
In script, in a b2b route, you can look at the callid or TO
tag (depending on the direction) to get the key :
http://www.opensips.org/html/docs/modules/2.2.x/b2b_logic.html#id294094
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.

Hi Bogdan,
Thanks for the information.
I need the value in the Opensips cfg.
I understand that I can query the b2b_logic or b2b_entities
tables to get the value in Opensips config. Apart from that
could you tell me other way to easily access the value in
Opensips config?
Thanks,
Ping

Hi Ping,
Indeed, my bad - the docs are not updated, as that param
was disabled long time ago (4 years ago):
https://sourceforge.net/p/opensips/bugs/502/
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.
