Unable to make Vowifi calls on Jio Fiber Connection

[sudipt123]

Hi All,

As per the subject, I am unable to make vowifi calls on both Airtel and Jio Network via my home Jiofiber connection. Jio CC not providing me with DNS IP's. Tried using cloudfare and google DNS, but unable to make it work. Also enabled IPSec Passthrough in Router settings.

TIA

Can you guys what IPs are these domains vowifi.jio.com and epdg.epc.mnc861.mcc405.pub.3gppnetwork.org resolving to in both the setups.

In windows you can do nslookup vowifi.jio.com. Or via Android App he.net - Network Tools - Apps on Google Play and under DNS section.

For wifi calling to work, they should ideally resolve to 49.44.59.38 or 49.44.59.36, if not try experimenting by changing DNS servers to 1.1.1.1 or 8.8.8.8 or 8.8.4.4 or any other internal jio dns servers

Tried nslookup both URL's,
epdg.epc.mnc861.mcc405.pub.3gppnetwork.org:- DNS request timed out
vowifi.jio.com: - *** UnKnown can't find vowifi.jio.com: No response from server.

Already tried Cloudfare and Google DNS settings on router/phone. No cigar

So what options do we have?

1. Get a router and link it to JCOW401
2. Rollback to June firmware (that is if we can grab it)
3. Change the ONT? Possibly???
4. Any other suggested hack to get this working?

I reached out to @jiosupport on twitter and they asked me the router settings with DNS SS and if Port 500 and 4500 are enabled. idk if ONT supports port opening.

Hi,
We need to single out the issue, is it with router/ is it with connection itself.

can you try below mentioned commands in your setup by changing a.b.c.d in commands to following ip's
IP's:
1.1.1.1
1.0.0.1

8.8.8.8
8.8.4.4

2606:4700:4700::1111
2606:4700:4700::1001

2001:4860:4860::8888
2001:4860:4860::8844

Commands:
ping a.b.c.d
nslookup epdg.epc.mnc861.mcc405.pub.3gppnetwork.org a.b.c.d
nslookup vowifi.jio.com a.b.c.d


Get the DNS in the WAN connection of your router let that ip be w.x.y.z.
ping w.x.y.z
nslookup epdg.epc.mnc861.mcc405.pub.3gppnetwork.org w.x.y.z
nslookup vowifi.jio.com w.x.y.z

Post the above results so that they might help in diagnosing the issue.

Also, try installing cloudflare warp in windows/android and see if the nslookup commands of vowifi.jio.com and other works fine.

I'm facing the same issue. The airtel vowifi symbol doesn't show when using my home jio fiber connection. Tech support from both jio and airtel haven't been able to help.

Have you tried a Indian VPN ?

Hi,

From the above logs DNS of 1.1.1.1 and 8.8.8.8 are working from your end. So I believe network wise everything looks decent.
There are probably 2 problems.
1. DNS of wifi calling are not resolving. By changing DNS in the router, we have to ensure that "vowifi.jio.com" is getting resolved correctly. [After changing DNS please cross confirm at What's My DNS Server? ]
2. Vowifi uses IPSec tunnel [isakmp - udp 500 and udp 4500 - ESP]. Someone earlier pointed that IPSec has issues in this firmware. We need single out if this indeed is the issue. Can try connect Cloudflar of any Indian VPN and test this out

 

[sudipt123]

@gvkr Thanks for the analysis. So do you mean to use a manual DNS entry in the router. Since I already tried using cloudfare and Google DNS. I have access to my Co. VPN located in India if that helps? So even after connecting to Indian VPN, below is the nslookup response

C:\Users\sudiptc.ttl.TMINDIA>nslookup epdg.epc.mnc861.mcc405.pub.3gppnetwork.org
Server: tmpnevinf02.tmindia.tatamotors.com
Address: 128.9.51.189

Non-authoritative answer:

49.44.59.38


C:\Users\sudiptc.ttl.TMINDIA>nslookup vowifi.jio.com
Server: tmpnevinf02.tmindia.tatamotors.com
Address: 128.9.51.189

Non-authoritative answer:
Name: vowifi.jio.com
Addresses: 49.45.63.2
49.45.63.1

Any clues from the above?

Yes, I would suggest you to use a manual DNS in router and do test again by nslookup.

In your company VPN, vowifi.jio.com is resolving through Singapore/foreign DNS servers hence it is not resolving to IP addresses 49.44.59.36, 49.44.59.38. [Jio has kept this check to ensure no abuse of vowifi during International Roaming].. The other one epdg.epc.mnc861.mcc405.pub.3gppnetwork.org is working fine in this VPN.

I would like you to change the DNS server to cloudflare/Google in your router and then test through nslookup command, both addresses should resolve to 49.44.59.36 or 49.44.59.38.[If still not working, check in What's My DNS Server? to ensure that Router is indeed sending DNS requests to the new DNS]. If DNS issue is ruled out, then we can test the router by probably connecting to free VPN where vowifi will work.

 

[sudipt123]

So I changed the router DNS to Cloudfare and upon nslookup vowifi.jio.com its getting resolved to above IPs

C:\Users\sudiptc.ttl.TMINDIA>nslookup vowifi.jio.com
Server: reliance.reliance
Address: 192.168.29.1

Non-authoritative answer:
Name: vowifi.jio.com
Addresses: 49.44.59.36
49.44.59.38
--------------
However when i use the DNS lookup inside the router admin page, i get below response

Server: 1.1.1.1
Address: 1.1.1.1#53

** server can't find vowifi.jio.com: NOTIMP

------------
What's my DNS gives below readings

Your DNS Server 49.45.31.133 Owner of this server Reliance Jio Infocomm Limited Status of this server Everything is fine

Your DNS Server 162.158.234.23 Owner of this server Cloudflare, Inc. Status of this server Everything is fine

Can we connect over PM ?

 

[sudipt123]

Hi Guys, Finally managed to get vowifi working over Jiofiber. A big thankyou @gvkr for the detailed analysis with patient timely responses. FYI have a JCOW401 black Jio router.

1. Route version ARCTF1_JCOW401_R1.24 (updated recently)
2. Got this working over cloudfare IPv4 DNS with Primary DNS Server: 1.1.1.1 and Secondary DNS Server: 1.0.0.1
3. Added it through the WAN IPv4 settings under search

This time it miraculously worked (had set the same Cloudfare DNS earlier on R1.16 firmware)

Please mark this thread as resolved.
