@UkakaK I'm on BSNL FTTH so other Airtel users might be able to help. Generally you will have to add the SIP server route first and have to monitor the return route on network monitor (if on Windows) and add that route too. In my case, 10.x.x.x for both server and the return route so I have a added 10.0.0.0 in ONU route table.

@UkakaK - you need to add the following static route in your PC:

route add 10.232.0.0 mask 255.255.0.0 10.127.248.1

Also add "ims.airtel.in" mapped to 10.232.142.146 in your hosts file.

After these you should be able to ping ims.airtel.in from your PC, before you try to connect your SIP phone!

@tellanand
I did add the static routes to my gateway and I can ping the gateway but I still cannot ping the SIP server(same as yours- ims.airtel.in) and I was wondering if you changed anything in your router. I did try adding the VOIP_INTERNET wan but my internet connection gets disconnected. If you could send me your router's configuration as well it'd be AMAZING!

Oh and also from your previous attachments in the thread you used your router as the proxy on MicroSIP. Should I also be doing that?
and right now whenever I try to connect it shows request timed out (I cannot ping the SIP proxy server)

So if you could send me the screenshots I'd be extremely grateful.
Thanks

@UkakaK - may be I should have asked this earlier. What's your network topology & configuration? Are you bridging VLAN660 (voice vlan) into your home lan? Can you share that?

​

 

[UkakaK]

@tellanand - Well I did try to create a new WAN profile with VOIP-INTERNET but i lost both my internet and the voice so I reverted to the default configurations. So the attached are my default config hoping I could get some help here from people who know their stuff.

@rajil.s , could you please explain your setup.. Are you using a Huawei H8145V5 and have connect a linux system directly via Lan. Installed a pfsense firewall on your linux system or have used a pfsense router with a Huawei H8145V5.

My setup is something like this Huawei H8145V5 > physical cable > TP-Link > WIFI > Mac

Huawei H8145V5 - voice profile setup as bridge & bonded to a LAN port

View attachment 4016

My setup is as follows:

Huawei HG8145V5 > pfSense router> Linux server running FreeSwitch.

The Huawei modem is set to pass both Internet and VOIP traffic on the same port using VLANS. Here are the relevant screenshots. Notice, I am not binding the LAN in the WAN profiles instead using VLAN Binding on LAN1 port. These tagged ports are untagged on the pfSense router.

Internet WAN profile, INTERNET_B_VID_100

VOIP profile, OTHER_B_VID_660

VLAN Binding Configuration

 

[tellanand]

@UkakaK - I dont have a Huawei router to vet your configuration. @rajil.s does.

I can give you are network topology and configuration - you should be able to map it to configurations on your PC and routers.

PC (SIP client) <--------------------------------> Router <---------------------------> Upstream Internet/Voice network
__________________VLAN660 (Voice)_________________________VLAN660 (Voice)
__________________Internet (Untagged VLAN)_______________VLAN100 (Data)
____________________________________________________________ IP address of VLAN660 interface = <your voice IP address> (10.x.x.x)

Static route on Router:
route add -net 10.232.0.0/16 gw 10.127.248.1

Hosts entry on PC/Router:
"ims.airtel.in" mapped to "10.232.142.146"

 

[UkakaK]

Thanks! But I don't have a downstream router so that's probably why I'm running into issues. But I do have one old computer laying around so it should work if I can install Freeswitch or FreePBX to route the VOIP signals properly right? Or do i need a downstream router and a Linux server while using VLAN binding on LAN1?

 

[sumitroop]

@UkakaK you do not need a FreePBX or Freeswitch if you want to use is directly on your old pc. Just enable the VLAN 660 / 666 in the bridge mode, provide a static ip of your voip profile to your system n that's all.

What is the password for the SIP account ?
