Possible to use the SIP/Voip from voice on FTTH with Freepbx or something similar?

@satek If you could clarify what you are trying to achieve and share config or screenshots from your end it would help.

@varkey Hi, Im trying to setup sip server on openwrt on Ea4500 and use BSNL FTTH voice as trunk. I just installed Asterisk on Openwrt Now need help on how to config Asterisk

satek · Apr 29, 2020

OpenWrt Project: Asterisk . this link gives example of German GSM as gateway

Interesting @satek, I never looked at Asterisk. But setting BSNL as a trunk on Asterisk certainly sounds like a good plan.

I don't think you'd find a ready to use Asterisk config for BSNL.

Please do post here if you make good progress.

Hi All
I have Netlink HG323RGW in bridge mode for both Internet and SIP with VLAN binding. Using Gl.Inet A750(Openwrt) as router.

Initially i tried without using siproxd and had no voice issue. Recently i came across this forum and read @varkey posts.

As per his suggestions i tried with siproxd. now i have one way speech issue. always sip client to other end voice silent.

Any suggestion to resolve this issue??

@ttraj Could you pls share your OpenWRT, siproxd , custom routes and other config details?

I've had a similar issue when the routes weren't setup correctly.

@varkey Firewall I allowed all for testing

Siproxd

static route for sip server

My Voice Interface in Openwrt.

@ttraj Your routes would need tweaks as the traffic is not able to go back. If you do a packet trace, you'd see the destinations. Also, rather than using a specific IP address, maybe use a range.

Also, what is your SIP server IP address?

Curious, though, are you on BSNL or some other ISP? Cause my understanding was that BSNL always assigns static IP address for voice. Did they start using DHCP (which is definitely the way they should have done it)

ttraj · May 5, 2020

Yeah.. they started using DHCP for new connection.
My sip server address 10.187.7.12. My assign ip range in 10.119.9.x level so i added static route to gateway

I checked pocket trace in PC(Where sip client installed) and From PC RTP going to siproxd port level(7070-7089).

That's good to know. They should have done that from the beginning, I wonder who came up with the idea that static IP addressing is manageable.

My sip server address 10.187.7.12. My assign ip range in 10.119.9.x level so i added static route to gateway

Yes, but I would start with having a wider route, at least a 10.187.7.0/24

I checked pocket trace in PC(Where sip client installed) and From PC RTP going to siproxd port level(7070-7089).

You would need to try from the OpenWRT device, from the PC, it may not show as you'd see traffic only to siproxd which is the proxy as you rightly noted.
