Thanks George

I originally didn’t have the 1002@ for the identify.  Changed that when things 
were not working.  I changed it back.

Unfortunately, the system I am connecting with doesn’t seem to support the line 
support.  Looking at the SIP packets, I see Asterisk send it.  Unfortunately, 
they do not send the line information as part of the INVITE.  I checked with 
some developers of that system and they do not know anything about the line 
setting.
Is there any rfcs I could refer them to?

Subject: Re: [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?

Currently using PJSIP.  First, they want me to get this working with the

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:1...@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 = 1...@xxx.xxx.xxx.xxx<mailto:1...@xxx.xxx.xxx.xxx>


Check this first...  identify112 probably failed to load because the match 
parameter can only take an ip address
plus an optional netmask, or a hostname.  The '1002@' is invalid.




I setup the registration and the endpoint.

[286]
type = aor
remove_existing = yes
contact = sip:2...@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:2...@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?

You may be able to use the 'line and 'endpoint' registration parameters...
[registration3]
type = registration
...
line = yes
endpoint = 286

This causes asterisk to put the encoded endpoint name in the outgoing Contact 
header.  If the provider properly echos back Contact parameters when sending 
responses or new requests, asterisk will use the line parameter to match an 
endpoint.  I'll have to double check but I believe we do that BEFORE checking 
any identify object for a match.
