Hmmm, 🤔I am not 100% sure but I feel this may not work. Using a different ONT and different ISP, if you are able to ping the SIP servers successfully, then it may work. Since the SIP servers are only accessible through the Airtel VLAN only and is not exposed to public internet, I doubt if you will be able to connect to it.

I feel this should be possible to achieve through SIP tunneling. But again if you don't know the sIp password, then its not worth trying it because the registration will keep failing due to incorrect password.

You need to try making it work in your ZyXEL ONT first.

There are a few youtube videos showing how to unlock the ZyXEL router but looks like all of them are using paid software to unlock it. 😕

The trustworthiness of those guys selling the unlock software is also questionable.

I am trying to use VSOL ONU with airtel voip config
1. WAN works fine on 1 port. VLAN ID setup a custom one as I had Nokia OLT
2. Added 2nd VLAN on 2nd port, connected IP Phone to it.
3. Added the static IP 10.0.0.0 for Voip in IP Phone. For SIP server tried 4-5 IPs, all connect and INCOMING calls work fine.
4. Issue - Outgoing calls from IP Phone do not work, get Call failed, NO RESPONSE

Also tried configuring IP Phone/Zoiper behing PFSENSE Firewall
In this case, Outgoing worked fine with IP Phone but incoming calls initiated from outside are not working.

FOR SIP Server used following servers and in all cases the connection is established fine.
10.5.70.19
10.2.9.181 etc

You don't need any static routes in the IP Phone if you're directly connecting it to a port with VLAN 660.
Just put the VLAN 660, voice WAN profile static IP, set up the SIP profiles and that's should be it, in most cases.
Now, as you're facing an issue with outbound calls, ensure you're prefixing a 0 to the numbers you're dialling, which you most likely are.
Secondly, check if the IP Phone has ALG settings and try tweaking them.
What make is your IP Phone, BTW? If it's Grandstream, set the NAT Traversal setting to Keep-Alive and check.

@Rajneesh Rana Same issue with me. I've unlocked my Airtel router (Dasan H660GM-A), so unfortunately they can't push VOIP updates anymore. I configured it, but only incoming works, no outgoing. Please let me know if/when you are able to fix it!
