Please help me Configure BSNL FTTH VoIP through Syrotech ONT on my Openvox IPPBX

[araghavendra]

@Audioctor am not much familiar with sip trunking, but I think it is simple SIP facility provided by BSNL and not any trunk which can handle simultaneous multiple calls, check if it can be configured in normal sip mode and not sip trunk,
If your requirement is multiple calls simultaneously like PRI then you have to take a SIP trunk facility from BSNL if am not wrong, you have to confirm with Openvox if it can take normal FTTH voice as input without SIP trunk
One more change is enable default route in WAN settings in pic you attached.

Thanks @araghavendra. But there is no option of configuring Simple SIP on Openvox. Its just SIP trunk. Besides, I connected the same Port of ONT to my PC. With the Network in DHCP mode, I tried to configure the SIP on Xlite. The PC network profile did acquire the IP address and DNS server parameters but the SIP profile on Xlite cannot seem could not be registered. I could not even ping the gateway 10.146.24.1 from the PC.

I hope I am not missing something here.

Just an update : After enabling the default route mode, the VoIP trunk is now online. But still I cannot make any outgoing or incoming calls.
Any ideas as to what else can be done?
The BSNL Tech person and my LCO so ignorant that it looks that they don't even understand what VoIP is . They keep talking about informing everything to their team at Pune...

Hello. As mentioned in the topic I have my BSNL FTTH connection landing on my Syrotech ONT modem. As I have mentioned in my previous posts, I am setting up a home IPPBX using an Openvox UC501. (I have an Airtel Fibre Connection as well, but I'll work on it later). My network is BSNL + Airtel Fibre O NT>>TP-Link R480T+ Load Balancing Router>> Netgear R6220 Router ( DHCP server for my Home Network) >> Openvox UC501 IPPBX. After reading through other forums, I have configured my WAN profile for Voice to Bridge mode and bound it to Port 2 of the modem. My IPPBX has 2 Ethernet ports: WAN and LAN. The WAN is connected to my home network with a static IP. I have tried connecting the LAN port to the Port 2 of my modem and setup the VOIP profile and SIP trunk on the IPPBX. But it doesn't work.Please help.
I have attached screenshots:
My VOIP WAN PROFILE
Voip Parameters
Gateway and DNS
IPPBX network parameters

As this has not worked, recently have made some changes to this system. I have replaced the TP-Link R480T+ with the Netgear R6220 flashed with Openwrt and mwan3 to work as load balancer. Netgear R6350 has replaced the R6220 as my main router now to which the IPPBX and IP phones etc are connected.
For now, I am just working on the BSNL VoIP.
I have the Syrotech ONT in Bridge Mode with VLAN tagged with Internet profile (VLAN 131) bound to Port2 and Voice profile (VLAN 1849) bound to Port1.
The port1 of ONT is connected to LAN Port 2 of Openwrt and configured as WANC (eth0. 131) while the port2 of ONT is connected to LAN port 3 of Openwrt and configured as BSNL Voice (eth0. 1849).
The WANC successfully acquires IP address via Pppoe and the Internet is live.
BSNL Voice also acquires the IP address in the Voice subnet through DHCP.
I have created static routes to the IMS server and Voice subnet via the BSNL Voice interface.
I can ping the default voice Gateway but not the IMS SIP server (cg.ftth.ims.bsnl.in which resolves to 10.191.177.49).
What do I do next...?

I did the configuration as suggested.
ONT Voice WAN profile in Bridge Mode with VLAN enabled
Port 1 of ONT connected to Openvox WAN port.
Openvox WAN in DHCP mode
SIP trunk configured in Openvox
Still it does not work.
I can ping the voice gateway 10.146.24.1 from Openvox though. Ping

What could be the problem now?

Is your IPPBX Working now with BSNL SIP?

 

[Audioctor]

No. Finally abandoned the idea and worked out a compromise. I have connected the telephone jack (FXS) to the FXO port of my IPPBX and configured the BSNL analog FXO trunk on the IPPBX.

Finally I have been able to sort this out.
