asterisk users - Nov 2017 - pjsip subscribe (presence) always returns: No matching endpoint found

Hello List

I am in the progress of migrating from chan_sip to pjsip.

I fear I have missed something on how hints need to be specified for
pjsip.

For chan_sip I have configured sip.conf

subscribecontext = localuser


and in the dialplan I set:

[localuser]
exten => 11,hint,SIP/11

Now if a phone subscribes to '11' this works.

Now I try to get the same working for pjsip. I understood that for
pjsip the hit needs to be placed in the same context as the endpoint:

[11]
type=endpoint
transport=transport-udp
context=localuser
disallow=all
allow=g722
allow=alaw
allow=gsm
auth=11
aors=11
callerid=(remove in this example
qualify_frequency=10
mailboxes=11
voicemail_extension=411

And in the dialplan I changed:

[localuser]
exten => 11,hint,PJSIP/11

But I constantly get:

Request 'SUBSCRIBE' from '"Beno?t Panizzon PJSIP"
<sip:11 at woody.ch>'
failed for '2001:4060:dead:d1d0:204:13ff:fe30:228d:2332' (callid:
ow21f3eg at snom) - No matching endpoint found

And I in the logger I see that the subscriber request is being rejected
with error 404.

Any hints what I'm doing wrong?

Have you checked the Asterisk console when PJSIP is loaded to see if the
endpoint did not load for some reason? Does it show up in "pjsip show
endpoints"?

Hi Joshua

thank you for the quick reply

Yes, the endpoint shows up.

 Endpoint:  11/(scrubbed from mail)                                       Not in
use    0 of inf
     InAuth:  11/11
        Aor:  11                                                 1
      Contact:  11/sip:11@[2001:4060:dead:d1d0:204:13ff:fe 58af7d6822 Avail     
5.799
  Transport:  transport-udp             udp      0      0  [::]:5061

I had the qualify statement at the wrong place, but that's sorted out now.

But still, subscribing to the hint results in a 404 error.

Acutualy, that subscribing is a bit odd, it's a snom M9 phone that is trying
to subscribe to itself.
That does not make much sense in my opinion.

It just that chan_sip reported OK to this and chan_pjsip replies with 404.
Or is pjsip more intelligent and trying to prevent the phone from subscribing to
itself?
