Posted: Mon Nov 18, 2013 12:04 am Post subject: [asterisk-users] CEL for attented transfer

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I'm trying to use CEL to display channel information in real time. It works fine for simple calls, blind transfers, or SIP attended transfers (initiated from the SIP phone). My problem is for Asterisk attended transfers (atxfer as configured in features.conf). The scenario is: . phone 107 calls phone 100, . 100 dials the atxfer code, . 107 is on hold, and 100 hears the transfer message, . 100 dials phone 103, . 103 answers, . 100 hangups, . 107 and 103 are connected, . 107 hangups. CEL is configured with apps=all and events=ALL, and events are stored in a database via cel_pgsql. This is the list of events in the database for this call: eventtype \| channame \| peer - -----------------+--------------------------------+------------------------------- CHAN_START \| SIP/107-0274 \| CHAN_START \| SIP/100-0275 \| ANSWER \| SIP/100-0275 \| ANSWER \| SIP/107-0274 \| BRIDGE_START \| SIP/107-0274 \| SIP/100-0275 CHAN_START \| Local/103@100-0042;1 \| CHAN_START \| Local/103@100-0042;2 \| CHAN_START \| SIP/103-0276 \| ANSWER \| SIP/103-0276 \| ANSWER \| Local/103@100-0042;2 \| BRIDGE_START \| Local/103@100-0042;2 \| SIP/103-0276 ANSWER \| Local/103@100-0042;1 \| BRIDGE_START \| SIP/100-0275 \| Local/103@100-0042;1 BRIDGE_END \| SIP/100-0275 \| Local/103@100-0042;1 ATTENDEDTRANSFER \| SIP/107-0274 \| Local/103@100-0042;1 CHAN_START \| Transfered/SIP/107-0274 \| BRIDGE_END \| Transfered/SIP/107-0274<ZOMBIE>\| SIP/100-0275 BRIDGE_START \| SIP/107-0274 \| Local/103@100-0042;1 HANGUP \| SIP/100-0275 \| CHAN_END \| SIP/100-0275 \| HANGUP \| Transfered/SIP/107-0274<ZOMBIE>\| CHAN_END \| Transfered/SIP/107-0274<ZOMBIE>\| BRIDGE_END \| SIP/107-0274 \| Local/103@100-0042;1 HANGUP \| Local/103@100-0042;1 \| CHAN_END \| Local/103@100-0042;1 \| HANGUP \| SIP/107-0274 \| CHAN_END \| SIP/107-0274 \| BRIDGE_END \| Local/103@100-0042;2 \| SIP/103-0276 HANGUP \| SIP/103-0276 \| CHAN_END \| SIP/103-0276 \| HANGUP \| Local/103@100-0042;2 \| CHAN_END \| Local/103@100-0042;2 \| LINKEDID_END \| Local/103@100-0042;2 \| (33 lignes) How should these events be interpreted?

Hi Jean, you mean what each event indicates? As this link explain?

Thanks for your reply, but I have read this page of the wiki, I know
what the fields mean.

What I don't understand is how the events in my example can be used to
determine 107 was attended transferred to 103 by 100.

Or I do know that Local/103@100-0042;1 and Local/103@100-0042;2 were
created by asterisk when SIP/100-0275 asked for atxfer?

How does the event ATTENDEDTRANSFER/ SIP/107-0274/ Local/103@100-0042;1
show that 107 is transferred to 103?

Thanks,

Hi Jean.

I am not sure but believe the sequence of CEL events should be considered for a more detailed understanding of a call.

Replicating the case you described I got this CEL event and fields:

*************************** 17. row ***************************
id: 27984
eventtype: ATTENDEDTRANSFER
eventtime: 2013-11-20 15:05:33
userdeftype:
cid_name: Jairo desktop
cid_num: 311
cid_ani: 311
cid_rdnis:
cid_dnid: 310
exten: 310
context: entrada-canal
channame: SIP/311-351096-0000048d
appname: Dial
appdata: SIP/310-777940,40,kKtT
amaflags: 3
accountcode:
peeraccount:
uniqueid: 1384967109.1184
linkedid: 1384967109.1184
userfield:
peer: Local/321@entrada-canal-00000001;1

The 3 extensions can be found in the event. Does it help?

Well, it is a way lot harder to figure out because you used
features.conf. Because of this, local channels are involved.

How does the event ATTENDEDTRANSFER/ SIP/107-0274/ Local/103@100-0042;1
show that 107 is transferred to 103?

Specifically, you are going to have to track the channel IDs and look at
the sequence of events. Then make an educated guess about what is
happening.

How do you link Local/321@entrada-canal-00000001;1 to the real original
(physical) channel ?

Right, but this is sometimes necessary, and it's an asterisk feature.

ok, but it could be so much easier (and reliable) if we had a CEL (or
AMI event) that tracks the requested atxfer, like the CLI debug message:

[Nov 20 13:09:28] DEBUG[12002][C-00000174]: features.c:2701
builtin_atxfer: Executing Attended Transfer SIP/CROcqu0s-000002b5,
SIP/ngqckJos-000002b6 (sense=2)

Or adding the physical channel in the extra field of the CEL when
CHAN_START event is fired for Local channels.

Thanks,
