Re: [asterisk-users] PJSIP: how to retrieve underlying SIP Call-ID

2015-10-07 Thread Michael Ulitskiy 
Hello Matt,

That works (CHANNEL(pjsip,call-id)). Thanks.

I'm still interested to know if PJSIP_HEADER is supposed to be able to read 
headers of the outbound channel.

I'm also very interested to know if there's any way in asterisk to access 
headers received in "200 OK" reply,
as my proxy returns some important information there.

Thanks a lot,

Michael

[asterisk-users] PJSIP: how to retrieve underlying SIP Call-ID

2015-10-06 Thread Michael Ulitskiy 
Hello,

I've started to play with PJSIP and got stuck at the following problem.
I need to retrieve SIP Call-ID associated with PJSIP channel. 
For inbound channel I can use ${PJSIP_HEADER(read,Call-ID)}, but that doesn't 
work for
outbound channel even in pre-dial or hangup handler. Whatever I do PJSIP_HEADER
seem to be unable to read headers for outbound channel.

Here's what I do:

[xyz]
exten => 999,1,NoOp(Call-ID: ${PJSIP_HEADER(read,Call-ID)})
   same => 
n,Dial(PJSIP/xyz011101/sip:xyz011101@:5060,30,b(_pre_dial,s,1))
exten => h,1,NoOp()

[_pre_dial]
exten => s,1,NoOp(Call-ID: ${PJSIP_HEADER(read,Call-ID)})
   same => n,Set(CHANNEL(hangup_handler_push)=_hangup,s,1())
   same => n,Return

[_hangup]  
exten => s,1,NoOp(Call-ID: ${PJSIP_HEADER(read,Call-ID)})
   same => n,Return


Here's the result:
-- Executing [999@xyz:1] NoOp("PJSIP/poly_650_2_01-006f", "Call-ID: 
e3e249e5-7e8941dd-da386565@192.168.100.238") in new stack
-- Executing [999@xyz:2] Dial("PJSIP/poly_650_2_01-006f", 
"PJSIP/xyz011101/sip:xyz011101@:5060,30,b(_pre_dial,s,1)") in 
new stack
-- PJSIP/xyz011101-0070 Internal Gosub(_pre_dial,s,1) start
-- Executing [s@_pre_dial:1] NoOp("PJSIP/xyz011101-0070", "Call-ID: ") 
in new stack
-- Executing [s@_pre_dial:2] Set("PJSIP/xyz011101-0070", 
"CHANNEL(hangup_handler_push)=_hangup,s,1()") in new stack
-- Executing [s@_pre_dial:3] Return("PJSIP/xyz011101-0070", "") in new 
stack
  == Spawn extension (xyz, 999, 1) exited non-zero on 'PJSIP/xyz011101-0070'
-- PJSIP/xyz011101-0070 Internal Gosub(_pre_dial,s,1) complete 
GOSUB_RETVAL=
-- Called PJSIP/xyz011101/sip:xyz011101@:5060
  == Using SIP RTP Audio TOS bits 184
-- PJSIP/xyz011101-0070 is ringing
-- PJSIP/xyz011101-0070 Internal Gosub(_hangup,s,1) start
-- Executing [s@_hangup:1] NoOp("PJSIP/xyz011101-0070", "Call-ID: ") in 
new stack
-- Executing [s@_hangup:2] Return("PJSIP/xyz011101-0070", "") in new 
stack
  == Spawn extension (xyz, 999, 1) exited non-zero on 'PJSIP/xyz011101-0070'
-- PJSIP/xyz011101-0070 Internal Gosub(_hangup,s,1) complete 
GOSUB_RETVAL=
  == Spawn extension (xyz, 999, 2) exited non-zero on 
'PJSIP/poly_650_2_01-006f'
-- Executing [h@xyz:1] NoOp("PJSIP/poly_650_2_01-006f", "") in new stack

As you can see I can get Call-ID of inbound channel, but I receive null for the 
outbound channel in both pre-dial and hangup handlers.

So my question is if there's a way to retrieve SIP Call-ID for outbound 
channels?
Also the 2nd question is if PJSIP_HEADER is supposed to be able to read headers 
of the outbound channel?

Thanks,
Michael

Hi Michael -

While you can use PJSIP_HEADER, the ability to retrieve the SIP
Call-ID through the CHANNEL function on a PJSIP channel was actually
just added in 13.6.0, and should be in the latest RC (13.6.0-rc2 [2]).

In either case, you're using a function as opposed to some
application, which means you do need to call the functions on the
specific channel. To get access to the outbound channel, you can use a
pre-dial handler's 'b' option [3]. The Call-ID *should* be set up on
the underlying invite session in the PJSIP dialog, even though it
hasn't been transmitted yet.
