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 ‘”Benoît Panizzon PJSIP” ‘
failed for ‘2001:4060:dead:d1d0:204:13ff:fe30:228d:2332’ (callid:
ow21f3eg@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?

  • The chan_pjsip module doesn’t prevent that. You’d need to provide the full SUBSCRIBE now that it is actually finding the endpoint and coming in.

  • Hi Joshua

    Ok, let’s see if we can solve the mystery..

    pjsip.conf

    [endpt-home](!)
    type=endpoint disallow=all allow=g722
    allow=alaw allow=gsm ice_support=yes context=from-home allow_subscribe=yes mwi_subscribe_replaces_unsolicited=yes

    [11](endpt-home)
    auth=11
    aors=11
    callerid=*scrubbed*
    mailboxes=11
    voicemail_extension=411

    extensions.conf

    [from-home]
    exten => 11,hint,PJSIP/11

    include=>local-extens include=>trunk-out

    This is the exact subscribe message and reply as recored by the Snom M9 Logging facility.

    I did also try all those variants:

    exten => 11,hint,PJSIP/11@woody.ch exten => 11,hint,PJSIP/sip:11@woody.ch exten => 11,hint,PJSIP/sip:11
    exten => 11@woody.ch,hint,PJSIP/11

    Any ‘hint’ welcome on why MWI subscription just does not work on those SNOM M9 phones.
