Identify by IP address ,match same IP in PJSIP?

Asterisk Asterisk Support
1

Hi,

We have 2 T1 connected to our Asterisk 13.4 and can only receive inbounds calls from one of the trunk because we cannot use the same ip address twice to identify anonymous requests.

The isdn to sip gateway has one ip address for both trunk and different port for each of the trunk.
The pjsip.conf below allows me to receive and make calls on TRUNK_1 but can only make outbound calls on TRUNK_2. I have tried setting up an anonymous endpoint in the pjsip file without success.
Is there any other way to accept inbound calls?

Here is my pjsip conf file:

;TRUNK 1 Inbound calls working from T1
[TRUNK_1]
type = aor
[color=#0000FF]contact = sip:XXX.XXX.XXX.40:5061[/color]
qualify_frequency = 60

[TRUNK_1]
type = identify
endpoint = TRUNK_1
[color=#00BF00]match = XXX.XXX.XXX.40[/color]

[TRUNK_1]
type = auth
username = username1
password = somepassword1

[TRUNK_1]
transport=transport-udp
type = endpoint
auth = TRUNK_1
outbound_auth = TRUNK_1
aors = TRUNK_1
context = FROM_PRI
dtmf_mode = info
disallow = all
allow = ulaw
ice_support = no
direct_media = no

;TRUNK 2 Inbound calls not working
[TRUNK_2]
type = aor
[color=#0000FF]contact = sip:XXX.XXX.XXX.40:5060[/color]
qualify_frequency = 60

[TRUNK_2]
type = identify
endpoint = TRUNK_2
;[color=#BF0000]match = XXX.XXX.XXX.40 (CANNOT USE SAME IP ADDRESS HERE)[/color]

[TRUNK_2]
type = auth
username = username2
password = somepassword2

[TRUNK_2]
transport=transport-udp
type = endpoint
auth = TRUNK_2
outbound_auth = TRUNK_2
aors = TRUNK_2
context = TO_PRI_2
dtmf_mode = info
disallow = all
allow = ulaw
ice_support = no
direct_media = no

What does the SIP messages show for an INVITE from trunk 2? (‘pjsip set logger on’ will turn on the logging). What is the dialplan logic? What is the device in use?

3

The gateway is a Mediatrix 3532 and the phone is a Cisco spa514G.

Here’s my dialplan for incoming call on TRUNK 2:

[TO_PRI_2] exten => 7808310,1,NoOp() same => n,Answer() same => n,Dial(PJSIP/U_6986,20) ;Dial same => n,Hangup()

Here is the logger:

There’s nothing really identifying it as coming from a second port. The only thing to do is send them to the same context and direct accordingly.
