Loosing the CALLERID due to attend tranfer

darkserg89 · September 26, 2019, 8:36am

Hello Guys, I see due to the Attend transfer the callerid on the phone “s” If I use sub-routine with exten “s” . I solved the issue by using “_X.” in sub-routing, but still thinking if it’s right or no, and probably there is a better solution. Probably, You can advices how to do it better.
The dialplan bellow:

[internal]
exten => 791,1,GoSub(sub-dial,s,1(${EXTEN},${INTERNAL_DIAL_TIME},${INTERNAL_DIAL_OPT}))
exten => 792,1,GoSub(sub-dial,s,1(${EXTEN},${INTERNAL_DIAL_TIME},${INTERNAL_DIAL_OPT}))
exten => 793,1,GoSub(sub-dial,s,1(${EXTEN},${INTERNAL_DIAL_TIME},${INTERNAL_DIAL_OPT}))
exten => 794,1,GoSub(sub-dial,s,1(${EXTEN},${INTERNAL_DIAL_TIME},${INTERNAL_DIAL_OPT}))


[sub-dial]
;ARG1 - exten, ARG2 - Dial Time, ARG3 - Dial Option
exten => s,1,NoOp("you are in sub-dial")
same => n,GoSub(sub-make-recording,s,1(${ARG1}))
same => n,GoSub(sub-make-dial,s,1(${ARG1},${ARG2},${ARG3}))

[sub-make-dial]
;ARG1 - EXTEN Number, ARG2-Dial time, ARG3 - Dial options
exten => s,1,NoOp('You are in sub-dial, arg3=${ARG3}')
same => n,Dial(PJSIP/${ARG1},${ARG2},${ARG3})
same => n,HangUp()

[sub-make-recording]
; {ARG1} - exten
exten => s,1,NoOp("lets recrord the phone ${ARG1}")
same => n,GotoIf($["${CALLERID(num)}"=""]?:named)
same => n,Set(CALLERID(all)=unknown)
same => n(named),GotoIf($["${DB(record_phone/${ARG1})}"="1"]?record)
same => n,GotoIf($["${DB(record_phone/${CALLERID(num)})}"="1"]?record:end)
same => n(record),StopMixMonitor()
same => n,Set(PATH=/var/spool/asterisk/monitor${STRFTIME(,,/%Y/%m/%d/%H:%M:%S-)}${CALLERID(num)}-${ARG1}-${UNIQUEID}.wav)
same => n,Set(CDR(file_path)=${PATH})
same => n,MixMonitor(${PATH},b)
same => n(end),Return()

Thank you in advance!

I don’t see how the extension would affect the caller ID, but you need to provide verbose logs, and any other evidence to show that someing is going wrong.

How is the attended transfer being initiated?

Hi david551,
I’m using *2 to make attended transfer:
here is some config from features.conf

[featuremap]
blindxfer => #1                
disconnect => *5               
;automon => *1                  
atxfer => *2                   ; Attended transfer  
parkcall => #72

The log descritption: from 415 calling to 792, from 792 doing attended transfer to 791, on the screen of the 791 phone, I see that the call comming from “s”

Here is some verbose log:

I’ve only used native SIP transfers, not features ones, but I suspect the problem isn’t with the transfer but with the original B side call.

I’d suggest investigating constructing your subroutines like the stdexten one in the sample configuration, and looking into connected line updates.

darkserg89 · September 26, 2019, 1:01pm

I’ve just found out the issue, I haven’t written callerid for endpoints in pjsip.conf. That’s why aster substituted callerid with EXTEN variable, as I understood. Anyway thanks for your help!
