[asterisk-users] PJSIP error No auth credentials for realm(s) 'asterisk' in challenge

[Administrator TOOTAI]

Hi all,

we are trying to move our servers from chan_sip to chan_pjsip. At this 
time no problems with phones, they all register fine and can place 
calls. But for a trunk we face problem and can't place calls despite the 
fact that registration is OK. What we get is:

[2018-04-16 16:08:33] WARNING[18665]: 
res_pjsip_outbound_authenticator_digest.c:178 
digest_create_request_with_auth_from_old: Endpoint: 'sip.xxx.tld': 
Unable to create request with auth. No auth credentials for realm(s) 
'asterisk' in challenge.

Our setup:

[sip.xxx.tld]
type = registration
retry_interval = 20
max_retries = 0
contact_user = <contactUser>
expiration = 3600
transport = transport-udp
outbound_auth = sip.xxx.tld
client_uri = sip:<contactUser>@sip.xxx.tld
server_uri = sip:sip.xxx.tld

[sip.xxx.tld]
type = auth
password = <password>
username = <contactUser>

[sip.xxx.tld]
type = identify
endpoint = sip.xxx.tld
match = <sip.xxx.tld IP address>

[sip.xxx.tld]
type = endpoint
context = from-xxx.tld
aors = sip.xxx.tld
deny = 0.0.0.0/0.0.0.0
permit = <sip.xxx.tld IP address #1>/32
permit = <sip.xxx.tld IP address #2>/32
dtmf_mode = rfc4733
disallow = all
allow = alaw,ulaw,g729

[sip.xxx.tld]
type = aor
contact = sip:<sip.xxx.tld IP address>:5060

Registry:

PJSIP is listening on port 12345, chan_sip on port 5060. The peer end is 
a Kamailio 3.3.4 if it matter.

What could be the problem? Does anyone have a PJSIP asterisk registered 
against Kamailio?

Thanks for any hints

Daniel
