Missed calls not showing on phone


I’ve successfully managed to get Alcatel IP Touch Phones (4018, 4028 and 4068) working with freepbx.
But if i don’t pick up a call, there’s no missed call warning…
I have not configured any queue or ring group.
I understand this is a bit of a niche problem, but maybe someone else came across this issue and fixed it.


What does the Reason header of the CANCEL request show? (Use sngrep to check.)

Thanks for your reply!

I’m not sure what you mean, but i’ve run the command and got this:

2021/05/11 18:43:43.294964 -> 192.168.xxx.xxx:5060
CANCEL sip:[email protected] SIP/2.0

CSeq: 5586 CANCEL

It doesn’t seem there’s a reason being sent.
Is this what you meant?


I think i figured it ou now:

I’ve saved the capture and looking at it, i see:

CSeq: 11562 CANCEL
Reason: Q.850;cause=0
Max-Forwards: 70
User-Agent: FPBX-
Content-Length:  0

There’s a reason being sent, but i have no idea if it’s what’s supposed to happen…

There is an optional reason header in the cancel that looks like this:

2021/05/11 15:17:51.194343 ->
CANCEL sip:[email protected]:1026;ob SIP/2.0
Via: SIP/2.0/UDP redacted:5060;rport;branch=z9hG4bKPj48571eb2-b57e-4b61-bb6e-b558b0b80567

Call-ID: 7b37c7a8-913b-479b-a7cd-24af57f6d2c5
CSeq: 31801 CANCEL
Reason: SIP;cause=200;text="Call completed elsewhere"
Max-Forwards: 70
User-Agent: FPBX-
Content-Length:  0

Some phones will use the reason header to suppress the missed call display, but that doesn’t appear to be your case.

Ok. Maybe something else.
