I am having trouble Registering Yeastar TG100 to Asterisk

Asterisk Asterisk SIP
1

Hello,

I am quite new to Asterisk and GSM sytems overall. I am currently trying to register a TG100 Modem to Asterisk. BUt it keeps returning a 401 Unauthorised error. Here is my asterisk configuration.

pjsip.conf

[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0:5060
local_net=192.168.178.0/24
; external_* lines are usually used behind NAT, but fine if you’re exposing public IP or STUN

; The Auth object for user 100

[tg100_auth]
type=auth
auth_type=userpass
username=100
password=1234
realm=192.168.178.37

; The AOR to hold our contact for 100

[tg100]
type=aor
max_contacts=1
contact=sip:192.168.178.55:5060
; The Endpoint definition

[tg100]
type=endpoint
context=default
disallow=all
allow=ulaw
auth=tg100_auth
aors=tg100_aor
direct_media=no
from_domain=192.168.178.37     ; force calls/regs to consider this domain
rewrite_contact=yes            ; sometimes helps if NAT or domain mismatch
force_rport=yes

; Option 1: Match by IP

[identify_tg100]
type=identify
endpoint=tg100
match=192.168.178.55

``
And my configuration on the Yeastar TG100

The name of the AOR matters, in Asterisk you have configured it as “tg100” while the REGISTER request is for AOR “100”. These need to match.

Also, why are you registering if the IP address is known and you’ve explicitly configured it in the AOR?

That name doesn’t match.

Thank You!

It seems to be registered now after matching the names. I didnt know that i could not register, if the IPs are known.
In all honesty I am kind of learning while I am doing. If you could recommend some resources so i can deepen my understanding of how the conenctions actually work it would be great!

Right now I am just trying to play a voice recording when a call is made to the sim card i installed in the modem, and then close.

Thanks again for the quick response and help!

The whole purpose of REGISTER is to provide an, otherwise, unknown address. It would be more accurate to say you SHOULD not register in this case.
