How to setup both Internet & SIP on same WiFi

akashayyappan · May 15, 2021

I am not able configure my router to achieve this.

I'm able to connect to internet when connected to wifi but my sip server is not working.

I tried to ping the SIP from my pc. It didn't work.

Then I enabled the Port biding for Voice to my wifi. Ping SIP work and able to connect to it and make calls. But internet doesn't seem to work.

If I enable port binding for my internet, SIP port binding gets reset and voice doesn't work.

I tried with disabling port binding in both Internet & Voice but only Internet works, I'm unable to connect to SIP server (even ping from pc to SIP ip)

Is there a way to use both Internet and SIP in same wifi.

Currently I have created another wifi in router and enabled port biding to 2nd Wifi for voice and I use 1st one for Internet. Works fine with this. But I want to use both in same phone.

Any help is appreciated. Thanks

As of now, SIP over Wifi, like those seen in JioFiber is not possible in BSNL FTTH, or is not properly configurable. Try setting the Service mode to Voice_Internet and bind to all ports. @sloj must be able to guide you further

I have set the service mode to Voice_Internet .

Actually I am able to setup the SIP over wifi and able to make and receive calls.

What I cannot do is, I am not able to bind both Internet and SIP in same WiFi port. If I bind to all port in Voice_Internet it resets the binding for Internet and I cannot use Internet in WiFi and lan. Without enabling port binding I am able to access Internet but not SIP.

Hey consider adding a static route for voice internet

akashayyappan · May 16, 2021

That just worked. Able to use both Internet and Voice on same WiFi.
I added static route earlier too. Maybe something was wrong.

Anyway thanks for the help.

I got one more problem now. Able to make calls but I'm only able to hear them, the opposite person is not able to hear me. Also I'm not receiving any calls if the other person dials me.

@Tx_JK · May 16, 2021

Could you mention the app you are using as a client?

akashayyappan · May 16, 2021

Nevermind. Restarting router did it. BTW I'm using ZoiPer in android.

@Tx_JK · May 16, 2021

Ahh yeah. I tried setting up SIP on native Android dialer. It never worked.
I used samsung, Xiaomi, realme devices. None of them worked. I wondered why?

akashayyappan · May 16, 2021

Can we do that?. I haven't thought about that. If yes, Maybe I will give a try and post the result.

@Tx_JK · May 16, 2021

Sure. You can do that. On realme and samsung, the settings are hidden in their UI. So you need to download Galaxy sip app. Xiaomi has a straight up SIP settings

Yes adding SIP account in native android dialer doesn't seems to be working. I have a OnePlus 7 Pro. It doesn't even register to SIP, says transaction terminated.

I actually mailed the modem company for help or external firmware to be flashed and they replied

Dear Thushar,
You said that third party softwares working fine with SIP calls in your Mobiles So that's clear it's not our device issue.
Maybe You can check with Mobile companies that this particular calling feature in their android mobiles support through wifi.

Thanks & Regards

I thought the same, maybe the native dialer is trying to connect through mobile data rather than through wifi.
