Hello all wanted to know is there any VOIP settings for AIRTEL xtreme fiber users if so how to access same using SIP settings ..thx
 
Thanks will try, otherwise will be getting erx in a while so will configure then.

Thanks a ton for figuring out the SIP password @tellanand . If possible , can you help us noobs out in setting up sip clients on android/pc by posting a tutorial/guide for airtel. I know its too much to ask. But would be really helpful for me and other members.

@rajil.s have you completely disabled the Voip profile in the Ont. If possible can you share the screenshot of the wan page where voip is configured. If disabled then where is the vlan (660)tagged? In the pfsense router?

You just need to bind a port to VLAN 660 like so. The traffic will be untagged on LAN2. Then on your downstream router, mimic the ip settings given to you by Airtel for VOICE.

I am poking at somebody else's Nokia G-140W-F. It has WAN defined as follows. This is only profile, and notice VOIP is not set.

However, the landline is fully functional and even the ONT shows the voice is registered.

I was curious to find out how is the VOICE traffic is routed. Using the telnet interface I found a network registered at VLAN 666.
Code:
pon_v666_0_1   Link encap:Ethernet  HWaddr xx:xx:xx:xx:xx:xx 
               inet addr:10.146.159.xx  Bcast:10.146.159.255  Mask:255.255.254.0

               TX packets:23191 errors:0 dropped:0 overruns:0 carrier:0
               collisions:0 txqueuelen:0
               RX bytes:4786470 (4.5 MiB)  TX bytes:4912583 (4.6 MiB)

10.146.158.0    0.0.0.0         255.255.254.0   U     0      0        0 pon_v666_0_1

So, it seems that Airtel also uses VLAN666 for Voice in addition to VLAN660.

@tellanand This is a stock installation from Airtel. Did you have a separate WAN profile for VOICE on stock installation?

@rajil.s - You are right. From the configuration it does appear that has this ONT has voice configured on VLAN666.

My stock configuration has voice configured on vlan 660, if that's what you are asking?!

@tellanand, when my Huawei router was commissioned by Airtel the first time their TR069/ACS script automatically created the VLAN660 profile. However, for this other Nokia router above this is not the case even though VOIP is functional.

I am guessing in your case too, Airtel automatically created a new VLAN660 profile.

The problem with not having a separate VOIP profile is that there is no direct way to get the static ip and gateway for the VOIP profile. You will have to go digging in the logs or use telnet like i did.

The reason it happened to me was because my authentication strings were not correct.

You will need to call Airtel and report your voice is not working. They will fix it for you from the backend. And before you start doing your experiments again, i suggest you use sngrep utility to watch what the sip traffic should be like from a known client (i pasted twinkle settings few posts back).
