@nishant2400 look at log files of your Nokia router. The connection details are specific to your location.

@rajil.s I do not see any connection details in my logs, I even don't have a separate voip profile as well. Everything is running on VLAN100 & also the IP range is different, it is starting from 122.176.X.X & subnet is 255.255.255.0. I have seen almost every screenshot pasted in this thread however I see either a subnet of 255.255.248.0 . I was able to telnet & dig the ip subnet & gateway information as u did in Nokia ONT, however creating that voip profile using that information on VLAN 660 is not helping as I am able to send TX packets however no RX packets coming backup. Have also added a route as well, have tried with all the possible username combinations as well 0120 followed by my landline no +91120 with my landline no . Any help here would be much appreciated

note : - have tried routes on both the interface, one on LAN100 & On LAN 660. no luck so far

Hi can you guys please share settings to be configured in Nokia ONT. My wan settings does not have voice profile still voice shows registered.

@nishant2400 , same is case with me

@sumitroop On the telnet interface if you do a

user(show)# network interface all

it will list the ipv4 and subnet alloted for voice traffic like so

pon_v666_0_1   Link encap:Ethernet  HWaddr blahblah
               inet addr:10.146.xx.xx  Bcast:10.146.xx.xx  Mask:255.255.254.0
               UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
               RX packets:65014 errors:0 dropped:0 overruns:0 frame:0
               TX packets:65152 errors:0 dropped:0 overruns:0 carrier:0
               collisions:0 txqueuelen:0
               RX bytes:13469121 (12.8 MiB)  TX bytes:13761836 (13.1 MiB)

The gateway for the voice traffic is revealed by arp

user(show)# arp    

ARP ENTRIES IN CACHE:

  (10.146.158.1) at **redacted** [ether]  on pon_v666_0_1


This is the ip to use on your downstream modem untagged VLAN.

The sip server ip is show at Status>Voice Information

Soft Switch 10.232.139.146

Here is what i suggest you can try.

1. Delete the inbuilt WAN profile, and create separate VLAN 100 and Voice VLAN 660 profiles (try with VLAN666 if 660 does not work)
2. Bind LAN2 to the Voice profile with connection type IPOE and Bridge
3. On the downstream modem or PC setup a static ip address with the details obtained from the above. Use the gateway as obtained from the arp.
4. Setup static route 10.232.0.0 via voice gateway found above from arp (e.g. route add 10.232.0.0 mask 255.255.0.0 10.146.158.1)
5. Check if you can ping to the softswitch at the ip address obtained above

@rajil.s , thanks a lot for the detailed explanation, I am using the Nokia ONT not the Huawei one so don’t have an option to bind on LAN2 or something, also wanted to use this on a Mac, iPhone & 3CX ip pbx system so do I add the route on ONT rather on the Mac / Windows machine.

Also wanted to understand how to get the outbound proxy, you have mentioned in your post that upstream & downstream servers are for Lucknow, how should I get those for my Location ( Noida)

Awaiting for your response, let me know if possible to have a quick chat over the phone

 

[rajil.s]

The outbound proxy is given under Status>Voice Information on the Nokia router.

The routes are to be added on the downstream device PC or router.

 

[sumitroop]

Oh okay, understood. So I should use the soft switch ip as an outbound proxy server with ims.airtel.in as my sip server.

 

[rajil.s]

I would set the hosts file so that ims.airtel.in resolves to the softswitch ip address.

I think you need to get bridge working first. Look at other threads how people got it working.

If you are able to buy the Huawei router from second hand market, i would throw away the Nokia router in trashbin.

 

[sumitroop]

What model number are you using, please share the same. I am okay to invest until I am able to make it work

Just clear out the confusion, outbound proxy we talked about earlier is soft switch ip & should be using the same ip as the ims server as well.

 

[rajil.s]

Huawei HG8145v5 works very well as a dumb bridged modem. I would use a secondary router downstream of it for routing/wifi ap.

ims.airtel.in and sip proxy server should be the same ip set to softswitch ip.
