How to identify isp ftth sip registration?

greetings to all,

possible to ask for insights on how could i identify the SIP registration that my ISP use?
so that i can replicate/transfer it for Asterisk use instead of the bland traditional telephone?

my purpose/goal is to have an ‘upgraded telephone system’ (to have more “flexibility”)
PITA sometimes using the telephone if it goes too long…, & i hope no one would push me w/ using something like linksys spa2102 & friends…

so anyways, some to take note on:
-: i know Asterisk for a long time but this is my first ‘tinker’ w/ it
-: my ISP wont help me in this matter (common w/ residential ISP, but not all)
-: pjsip.conf below are bits N pieces from the wild…, put together

the info i got from my ISP side of things…
note: i’ll just use alias instead of the actual ip & url (if this is not okay, please let ke know)
-: 0448888888 (username is in the format of XYYZZZZZZZ, XYY is area code + ZZZZZZZ the telephone number)
-: 1234 (some password)
-: SIP ProxyServer=“10.143.44.88”
-: RegistrarServer=“some.sip.provider.com
-: there are no 2nd proxy server defined
-: there are no gateway defined as well…

on the hardware/software side of things…
-: the VOIP vlan is set to ‘bridge mode’ and binded to LAN2 of the modem…
-: then LAN2 goes to (eth5) to my virtualized OpenWRT via Proxmox (all ethernet is passed-thru, all owned physically by OpenWRT)
-: eth5 is set to DHCP (v4 only) (i’m getting: 5.x.x.x /18, a GINORMOUS network!!!)
-: the DNS servers that is on eth5 has 2 entries (from DHCP), both are 255.255.255.255 (funny, scary or something else?)
-: for some reason, ‘SIP ProxyServer’ & ‘RegistrarServer’ appears the same thing but cannot PING it.
-: Asterisk is installed inside OpenWRT

i tried to read: asterisk/configs/samples/pjsip.conf.sample at master · asterisk/asterisk · GitHub
and below is my pjsip.conf monstrosity (but am still confused…)

[global]
type=global
user_agent=""
debug=yes

[transport-udp]
type=transport
protocol=udp
bind=0.0.0.0:5060

[registration_myISP]
type=registration
outbound_auth=auth_myISP
server_uri=sip:some.sip.provider.com
client_uri=sip:0448888888@some.sip.provider.com
contact_user=0448888888
retry_interval=60 ;change to 30 afterwards if it is working
forbidden_retry_interval=600
expiration=3600
transport=transport-udp

[auth_myISP]
type=auth
auth_type=userpass
username=0448888888@some.sip.provider.com
password=1234 ;majority mentioned, this is the right password ^_^
realm=some.sip.provider.com

[myISP_aor]
type=aor
contact=sip:0448888888@some.sip.provider.com
qualify_frequency=60

[myISP_endpoint]
type=endpoint
context=internal
disallow=all
allow=ulaw,alaw
aors=myISP_aor
outbound_auth=auth_myISP
from_user=0448888888
from_domain=some.sip.provider.com
rewrite_contact=yes

[myISP_identify]
type=identify
endpoint=myISP_endpoint
match=some.sip.provider.com

so with what i learned (or not), below is the result…

Host: '10.143.44.88:5060': No auth objects matching realm(s) 'Huawei' from challenge found.
Failed to create authenticated REGISTER request to server 'sip:0448888888@some.sip.provider.com' from client 'sip:0448888888@some.sip.provider.com'
Fatal response '401' received from 'sip:0448888888@some.sip.provider.com' on registration attempt to 'sip:0448888888@some.sip.provider.com', stopping outbound registration

any hints perhaps on my predicament?
PS: kindly delete this post if the citizens here finds my post unfit for the forum.

thank you for your time reading my post!
later & good day to all!

note: i’ll just use alias instead of the actual ip & url (if this is not okay, please let ke know)

Not really. If you’re changing IPs and hosts then nothing you says makes sense or is trustworthy.

I get that you need to anonymize…but you’ve chosen IP ranges that are public or don’t make sense.

I’m just going to say I don’t think you’ll get this working. I don’t have enough information to understand what you’ve done. It sounds like you jammed packets in places in ways that just won’t work. without knowing where the packets are supposd to go, or IPs, or actual network topology…meh.

My FTTH provider doesn’t even run it’s voip on the public range. It’s a private feed directly over the fiber to their hardware. It’s not even sip.

You sure yours is SIP?

does my 1st example output not enough to say/indicate it as SIP?

Host: '10.143.44.88:5060': No auth objects matching realm(s) 'Huawei' from challenge found.
Failed to create authenticated REGISTER request to server 'sip:0448888888@some.sip.provider.com' from client 'sip:0448888888@some.sip.provider.com'
Fatal response '401' received from 'sip:0448888888@some.sip.provider.com' on registration attempt to 'sip:0448888888@some.sip.provider.com', stopping outbound registration

anyways,
there is a ‘restart voip’ on the modem & a packet capture option as well…
started the packet capture, restarted the voip service, wait for a minute, tried to lift the phone to see if there is dial tone, dialed some outbound number, wait for the ivr then hangup. below capture is from the modem itself (original configuration) & utilizing the telephone… (not using Asterisk yet)
note: these are actual values…

is there information that i missed? or do i need to supply some info that i am not aware of? as i have placed all info on my post.

anyways, will i ever make this work? i don’t know & maybe not, however & “i believe” the only thing missing on my end is the Authentication/Registration part, as the REGISTER portion of the original modem VS the one that i’ve created is ‘similar’

all-in-all, i thank you for your time replying to me.

– edit:
i corrected the proper realm on the auth part & i am able to get the ‘200 OK’ as a response.

thank you all!
