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
 
Could someone please guide me through the changes on the router side, I have tired binding LAN 4 but it just doesn't work. My Microsip just keep saying "request timeout". I have added the screenshot of the microsip configuration below. Thank you for you're help.


Router Model: Nokia G-2425G-A

If you save the router config and open the xml file you will get some thing like this:

Code:
<SIP AuthUserName="+91<phonenumber>@ims.airtel.in" AuthPassword="<password>" URI="" SIPEventSubscribeNumberOfElements="0">

<X_HW_Digitmap DMName="" DigitMap="" DigitMapStartTimer="20" DigitMapShortTimer="5" DigitMapLongTimer="10"/>

</SIP>

I believe you can use this password.

@Dino Do not try to register more than 1 device on the server, it will block registration for 1 day before you can reuse your landline connection.

Hi,

Has anybody got this working with the Airtel BDT-121 ONT? My setup is BDT-121 (bridge mode) -> Netgear R6220 -> Computer. I also have other computers behind an additonal router - so those would be BDT-121 (bridge mode) -> Netgear R6220 -> TP-Link Router (access gateway) -> Computer.

On the ONT side, i'm unsure as to how to do the VLAN binding similar to the post here - Is there VOIP service/SIP settings in AIRTEL xtreme fiber broadband | Airtel Xstream Broadband

This what I have on the ONT side so far,

I don't see any VLAN binding option in the Routing options of the router though

Any idea on how I should proceed from here?

On the Netgear router, when I try to enable VLAN mode, I lose internet connectivity.

Ideally, I would like to be able to get Voice and Internet on all the ports, but, I guess I'll have to somehow do some binding on the ONT for this? Would appreciate some help 🙂 Thanks

I found this setting on my ONT which I believe does the binding like @ragil.s has.

However, I'm still not able to ping my voice gateway IP from openwrt. My current openwrt config has the following entries

Code:
config switch_vlan
        option device 'switch0'
        option vlan '3'
        option vid '660'
        option ports '4t 6t'

config interface 'Voice'
        option ifname 'eth0.660'
        option proto 'static'
        option netmask '255.255.240.0'
        option ipaddr '10.101.x.y'
        option gateway '10.101.a.b'
        option defaultroute '0'

config route
        option gateway '10.101.a.b'
        option netmask '255.255.240.0'
        option interface 'Voice'
        option target '10.232.139.0'

config route
        option gateway '10.101.a.b'
        option netmask '255.255.240.0'
        option interface 'Voice'
        option target '10.101.144.0'

any pointers on how to set this up in openwrt would be appreciated. Thanks

My Configuration

Code:
config switch_vlan
    option device 'switch0'
    option vlan '660'
    option ports '8t 2t'

config interface 'voip'
    option ifname 'eth0.660'
    option proto 'static'
    option ipaddr '<Your IP Here>'
    option netmask '255.255.255.0'

config route
    option onlink '1'
    option netmask '255.255.0.0'
    option target '10.232.0.0'
    option gateway '<Gateway IP Here>'
    option interface 'voip'

What is the last route in your config for though?
And are you trying to ping from the openwrt box or from a pc on the network?

Hmm..so, am unable to get it to register even with a softphone (zoiper lite on iOS) - although this doesn't seem to have a SIP Proxy field. So, I ended up just filling it in the Domain field. With Zoiper, I get a 403 Forbidden, while with Cisco Phone I get a 400 error. Do we have to do anything else - perhaps with Firewall or NAT settings? I tried installing siproxd on the openwrt router as well - but, the default settings didn't seem to help.

Have you set the Outbound Proxy properly on Zoiper?
Because ims.airtel.in is just the registrar, all the actual SIP signalling is done by your local airtel SIP proxy.

If you want to use multiple devices on the same line, you will have to install a B2BUA on your OpenWRT box, like YATE, which will handle registration on local network and act like a dummy client to the actual Proxy.

Note that you should never try registering more than one device at a time on the Airtel Line, the registrar will blacklist your IP for 1 day, which might explain the 403 forbidden error on Zoiper, given that everything else is set up properly.

I'm just trying one device at a time. When I reset my ONT settings, and connect my phone to the port on the ONT, it works (and SIP status in ONT is Active) - this is right after the 403. So, I don't think i'm getting blacklisted.

For the outbound proxy, I'm just filling in the same outbound proxy address from my ONT voice settings page.

Did you set an entry in ims.airtel.in on the OpenWRT hosts file mapped to your proxy address (I did this similar to what earlier posts in this thread said).

At the moment, I can't register - either timesout or 403...

The only other difference I can think of is on the ONT WAN Voice interface, I've set the mode to Internet (while earlier posts seem to indicate we have to set it to Other). When it's set to Internet, I can ping the voice gateway and SIP proxy servers. But, with mode set to Other I'm not able to...
