Description:Hello. Faced a bug: sending PJSIPShowContacts action from ami libraries (panoramisk, ami-py) says "Message='No Contacts found' Response='Error' content=''>". while asterisk -rx 'pjsip show contacts' - shows contacts.


script example is here

from panoramisk import Manager
import asyncio

@asyncio.coroutine
def check_peers():
   manager = Manager(loop=loop,host='127.0.0.1', port=5038,username='123', secret='123')
   try:
       yield from manager.connect()
       peersobj = yield from manager.send_action({'Action': 'PJSIPShowContacts'})
       return peersobj
       manager.close()
   except:
       return 'oops...something is wrong'

loop = asyncio.get_event_loop()
peers = loop.run_until_complete(check_peers())
print(peers)


Other ami-commands (like PJSIPShowEndpoints, etc.) work fine.


here is nmap output

I found out the following: if peer was created in pjsip.conf - PJSIPShowContacts action - shows the peer. (example config -
[6001]
type=endpoint
context=internal
disallow=all
allow=ulaw
auth=auth6001
aors=6001
transport=udp-transport

[auth6001]
type=auth
auth_type=userpass
password=6001
username=6001

[6001]
type=aor
max_contacts=1
qualify_frequency = 60)


But if peer is pjsip_wizard -based - PJSIPShowContacts don't show it. Here is my wizard example -

[trunk_defaults](!)
type = wizard
transport = udp-transport
endpoint/allow_subscribe = no
endpoint/allow = !all,ulaw
aor/qualify_frequency = 30
registration/expiration = 1800
endpoint/inband_progress = yes

[telecomsxchange](trunk_defaults)
endpoint/context = from-trunk
remote_hosts = sip01.telecomsxchange.com:5060
sends_registrations = no
accepts_registrations = no
sends_auth = no
accepts_auth = no

It appears you are using an older version of Asterisk. Does it still do this in the latest version?

--Also please attach your _pjsip.conf_ configuration.--
Edit: nvm I see you've done that now above
By: Mikhail (j3st3r) 2020-12-10 12:22:29.637-0600

I've updated Asterisk to current 16 version (16.15.0), the problem still exists.

One more update: looks like it doesn't depend on pjsip or pjsip_wizard configuration. Looks like if peer has inbound registration (configured as internal extension) - PJSIPShowContacts shows it, but if peer has outbound registration or without registration - doesn't.

Does anyone work with the issue?
By: Joshua C. Colp (jcolp) 2020-12-15 04:00:51.009-0600

There is noone working on this issue at this time. If that changes then it will be assigned and transition to "In Progress".

This issue is still present in 16.28.0 and 18.14.0

The static contacts arent displayed by the AMI action {{PJSIPShowContacts}}

On my test server {{pjsip show contacts}} returns 44 contacs and {{PJSIPShowContacts}} only 9.

This issue prevents our software to monitor the qualify status of peers without registration.

I make a patch. Ut solve problem for us. But i dont know how to fill endpoint name so i use aor name instead. Its not problem for us because we always use same name for both. Maybe someone can make it better. Also im not experienced C programmer :(.  I just tried copy algorithm for cli pjsip show contacts command. At first i have no idea why there are separate places for static contacts and dynamic. Patch include some debug log messages, we testing it now, you can remove them for production usage. Works with 18.11.3.
