Unable to bind new PJSIP trunk to new IP

Asterisk Asterisk SIP
1

Hello Asterisk experts,

I have an Asterisk 13.8-cert4 server.

Two ethernet interfaces on the same physical ethernet cable are as follows:

inet 10.36.1.234/30 brd 10.36.1.235 scope global eth0:1
inet 10.42.1.242/30 brd 10.42.1.243 scope global eth0:3

We have two SIP trunks (k and z) as follows:

===========================
[k-transport]
type=transport
protocol=udp
bind=10.36.1.234:5060

[z-transport]
type=transport
protocol=udp
bind=10.42.1.242:5083

[k]
type=endpoint
transport=k-transport
context=fromk
aors=k
direct_media=no
force_rport=yes
rtp_symmetric=yes
rewrite_contact=no

[z]
type=endpoint
transport=z-transport
context=fromz
aors=z
direct_media=no
force_rport=yes
rtp_symmetric=yes
rewrite_contact=no

[k]
type=aor
contact=sip:8.18.248.36:5060
qualify_frequency=60

[z]
type=aor
contact=sip:8.18.252.10:5083
qualify_frequency=60

[k]
type=identify
endpoint=k
match=8.18.248.36

[z]
type=identify
endpoint=z
match=8.18.252.10

The problem is in the bind address for z endpoint. It’s being bind to 10.36.1.234:5083 (the k bind IP with z bind port) instead of 10.42.1.242:5083 :

localhost*CLI> pjsip show endpoint k

Endpoint: k In use 3 of inf
Aor: k 0
Contact: k/sip:8.18.248.36:5060 41079c9907 Unavail 0.000
Transport: k-transport udp 0 0 10.36.1.234:5060
Identify: k/k
Match: 8.18.248.36/32

localhost*CLI> pjsip show endpoint z

Endpoint: z Not in use 0 of inf
Aor: z 0
Contact: z/sip:8.18.252.10:5083 53a7955766 Avail 5.132
Transport: z-transport udp 0 0 10.36.1.234:5083
Identify: z/z
Match: 8.18.252.10/32

Any help resolving this is highly appreciated.

What does the console say it is binding to when starting up Asterisk?

3

Would you please remind me how to log the output of asterisk startup command, then I can see what it does say?

4

I remember it was something similar to:

asterisk => /var/log/startup.txt

Is it correct? I would make it once only as it will require stopping Asterisk for testing this.

It is configured in logger.conf, you can send every level to a file. You can also just shut down Asterisk, run it in console, copy/paste the output to a text document, and then restart Asterisk normally.
