[asterisk-users] Is it possible to have two endpoints to the same IP address where one uses IP based authentication and the other requires asterisk to register to that system?

[Dan Cropp]

Currently using PJSIP.  First, they want me to get this working with the existing PJSIP configuration, but then setup a second box using chan_sip performing similar work.

For PJSIP...
I currently have an endpoint configured to a system using IP based authentication.  It is configured with a match setting in the endpoint section.
All channels coming from that IP address go to this endpoint.

They want me to keep this endpoint, but add a new endpoint where we register with them.

Existing...
[transport1]
type = transport
bind = 0.0.0.0
protocol = udp

[1002]
type = aor
remove_existing = yes
contact = sip:1002 at xxx.xxx.xxx.xxx

[1002]
type = endpoint
context = mycontext
transport = transport1
accountcode = 6
dtmf_mode = inband
device_state_busy_at = 48
force_rport = no
identify_by = username
from_user = 1002
disallow = all
allow = ulaw
acl = acl1

[identify112]
type = identify
endpoint = 1002
match = 1002 at xxx.xxx.xxx.xxx

I setup the registration and the endpoint.

[286]
type = aor
remove_existing = yes
contact = sip:286 at xxx.xxx.xxx.xxx
qualify_frequency = 60

[auth8]
type = auth
username = 286
password = yyyyyyyyyyyyyyy

[286]
type = endpoint
context = mycontext
transport = transport1
outbound_auth = auth8
aors = 286
accountcode = 22
dtmf_mode = inband
device_state_busy_at = 48
force_rport = no
disallow = all
allow = ulaw
acl = acl1

[registration3]
type = registration
transport = transport1
client_uri = sip:286 at zzz.zzz.zzz.zzz
server_uri = sip:xxx.xxx.xxx.xxx
contact_user = 286
outbound_auth = auth8
expiration = 3600

The registration for the second endpoint works fine.  However, when I call through the other system for 286, it is failing.  For the INVITE from the other switch, the from_user varies depending on who is calling.  Asterisk logs report "No matching endpoint found" when it processes the INVITE for 286.

I believe the reason INVITEs work for the other channel is because they are programmed to support the match for this IP address.

Can anyone offer some suggestions?
