Thanks Joshua for your quick answer.
I am indeed referring to outgoing calls.
The contacts are created as a result of an inbound registration.
Before the first registration I only have dual entries for the endpoints.
After the first registration I see the 2 contacts, which are in fact identical.
The database itself only contains a single entry for all entities, which would
explain why it
works after a restart.
The workflow is as follows.
1 - Create endpoint/auth/aor for Alice using ARI push configuration
2 - Create endpoint/auth/aor for Bob using ARI push configuration
I see two entries for each of them when issuing "pjsip show endpoints"
3 - A registers and a contact is created
2 (identical) contacts are shown as "Available", since there are also two
endpoints shown
4 - B registers and a contact is created
2 (identical) contacts are shown as "Available", since there are also two
endpoints shown
5 - Alice tries to call Bob
Asterisk refuses with
res_pjsip.c: Endpoint 'Bob': Could not create dialog to invalid URI 'Bob'.
Is endpoint registered and reachable?
chan_pjsip.c: Failed to create outgoing session to endpoint 'Bob'
app_dial.c: Unable to create channel of type 'PJSIP' (cause 3 - No route to
destination)
app_dial.c: Everyone is busy/congested at this time (1:0/0/1)
pbx.c: Auto fallthrough, channel 'PJSIP/Bob-00000814' status is
'CHANUNAVAIL'
I have seen this already more than a year ago with 13.x and 14.x as well
(currently I'm using the latest 15.3.0).
I was not able to reproduce it since as everything works flawlessly after a
restart.
It was only now that I realized that the issue is related to creating the
endpoint/auth/aor objects on a running system with no restarts since.

If you are referring to inbound calls from the endpoint then that would be
unrelated to your Contact issue. Inbound registration isn't consulted or used
for incoming calls. Are you actually referring to outgoing calls to the
endpoint? As well - is there anything different between the contacts?

I don't know if anyone has tested the use of ARI push configuration with a
database backed realtime, albeit there is nothing to say it shouldn't work.
What do you see in the actual database?
