Setting Up Asterisk with PJSIP for Internal Calls (No SIP Provider)

Asterisk Asterisk Support
1

I recently set up an Asterisk server with PJSIP to allow internal calls between two users (1001 & 1002) without an external SIP provider. However, I ran into some issues registering with Zoiper (404 Not Found).

thats the pjsip.conf:

[global]
external_media_address=10.0.122.100
external_signaling_address=10.0.122.100
local_net=10.122.70.0/24

[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0:5060

[1001]
type=endpoint
auth=auth1001
aors=1001
context=from-internal
disallow=all
allow=ulaw,alaw

[auth1001]
type=auth
auth_type=userpass
username=1001
password=SecurePassword1001

[1002]
type=endpoint
auth=auth1002
aors=1002
context=from-internal
disallow=all
allow=ulaw,alaw

[auth1002]
type=auth
auth_type=userpass
username=1002
password=SecurePassword1002

and thats the dialplan:

[from-internal]
exten => _XXXX,1,Dial(PJSIP/${EXTEN},20)
exten => _XXXX,n,Hangup()

You can’t put this in global.

In the provided configuration there are no AORs defined, so registration would not be possible.
