Issue with calerid when using the SLA

Asterisk Asterisk Support
1

Hi,

I am using asterisk 13 and set up the SLA with the pjsip channel.

  1. When the incoming call comes in it goes to line1 and line1 will dial the station/extension 8883,8884
    (at this point, caller id works perfectly fine)
  2. 8883 picks up the call and BLF updates the LED
  3. 8883 puts the call on hold
  4. Now, when 8884 connects to the line1 by pressing the line1 key, 8884 is not getting the caller id

Configuration files

sla.conf:

[general]
attemptcallerid = yes

[line1]
type = trunk
device = Local/disa@line1_outbound

[line2]
type = trunk
device = Local/disa@line2_outbound

[station] (!)
type=station
trunk=line1
trunk=line2

[8883] (station)
device = PJSIP/8883

[8884] (station)
device = PJSIP/8884

extensions.conf:

[line1]
exten => s,1,NoOp(Transfering to available line)
same => n,SLATrunk(line1);

[sla_stations]
exten => 8883,1,SLAStation(8883)
exten => 88831,hint,SLA:8883_line1
exten => 88831,SLAStation(8883_line1)
exten => 88832,hint,SLA:8883_line2
exten => 88832,1,SLAStation(8883_line2)

exten => 8884,1,SLAStation(8884)
exten => 88841,hint,SLA:8884_line1
exten => 88841,1,SLAStation(8884_line1)
exten => 88842,hint,SLA:8884_line2
exten => 88842,1,SLAStation(8884_line2)

Any help would be appreciated.

Thanks.

You haven’t provided the PJSIP configuration, which can alter behavior for connected line updates.

You don’t appear to have enabled support for sending connected line updates. This is done using the “send_rpid” and “send_pai” options.

I tried but it is still not working.
Following is the new endpoint section.

type=endpoint
transport=simple
allow_subscribe=yes
context=sla_stations
send_pai=yes
send_rpid=yes
disallow=all
tos_audio=cs7
cos_audio=7
rewrite_contact=yes
dtmf_mode=rfc4733
allow=ulaw,h263,h264
mailboxes=999@vm_setup

Am I missing something?

That should update connected line information, that’s the extent of what I know in regards to this. SLA I have no experience with and noone really uses it anymore from what I can see.

OK. Thanks.

Also, is it possible to get multiple lines for one credential?

Suppose, user12 is registering with SIP server in the given example. Can I associate the user12 to line1 and line2? So that when incoming call is coming in it will go to line1 and line1 is busy it will automatically goto line2.
