Bug description

Network Failed! happening several times in last 2 months when calling between our Samsung S8s

Steps to reproduce

• Do an audio or video call
• Phone that makes the call rings for a bit (maybe 5 seconds) so you think it works OK, then you get network failed!
• Random, 2 times it works fine, 2 times it drops and you have to call twice every time. more often audio only drops

Expected result: Call to connect first time properly, like Telegram or Whatsapp, etc

Device info

Device: Samsung S8
Android version: 9.0
Signal version: 4.79.3

Debug Log: https://debuglogs.org/9c10750e9a950dca5dfdee99f64597357725d0c583a4b07597ca7365eb13ac02

again, this was happening today - i had low signal in a shop, and "signal" couldn't get a phone or audio call no matter what! not even messages. I managed to have a choppy video call on WhatsApp and an OK normal voice call. Why is Signal so struggling to connect when the signal is not PERFECT? when the video calls work they are beautiful but it seems that if everything isn't perfect signal wise (can't get any other word sorry), then it will not even bother connecting and not even delivering messages.

Can you please address these issues? i want to use Signal more and more but this makes it unusable :(

have to report it again, today, called my contact that uses Signal, call, ring ring ring ring for 30 40 seconds, call just went off on my end, then called again, and other end ringed and picked up, when i asked "hey did you hear it ring, other end said no", so this consistently happens.

My phone was on 4G LTE on KPN (NL) 4G+ full signal and other end was on strong wireless indoors.

The exact opposite happens to me since a couple of weeks ago. I can make calls successfully but when I get a call, phone doesn't ring at all only displays a network error and a missed call afterwards. Tested on both good cellular and wifi networks, same.

ok this only confirms that something's going on and they should fix it.

I can confirm this issue too, if developers need more logs I can provide them since it is quite reproducible. I'm using pixel 3, and for my expirience is something that does happen only amoung android phone

I've tried to reproduce this issue today with 2 phones running Signal 5.0.8(7592).

Device 1: xiaomi mi9t, rooted, no gapps (microg only), resurrection remix 8.6.3 a10 aosp rom.

Device 2: samsung a31 (SM-A315F/DS), no root, full gapps, oem a10 rom.

Issue: Device 1 can successfully call device 2 without any problems whatsoever. However when device 2 tries to call device 1, following happens in device 1:

• Incoming call notification comes in but neither call ui comes up nor phone rings.
• If Signal is in foreground it gets closed gracefully and incoming call notification disappears.
• No indication of a call reappears at all even if Signal gets opened by user afterwards.
• Missed call notification comes in after device 2 eventually hangs up after timeout.

Here is my debug log:

thanks for sharing @Blacktail92 - i really hope they pick this one up as it's not just one or two people...

[gab81]

and by the way, it should always ring when you "don't know" somebody is calling you, obviously otherwise it defeats the purpose.

[gab81]

did anyone have any luck from support with this? happened again today, called my wife, ring ring ring ring, then failed, then called her again, asked her hey did it ring? No. disappointing. how can you even know if it rings

[n0sign4l-official]

Hi, please do not bump issues, they will look into it asap, they are probably on vacation rn. Let's just wish them the best holidays, they did an amazing job in 2020. Keep up the good work signal team!

[gab81]

sorry but i have to share this one again

again network failed. i turned on the option in sms mms for wifi calling compatibility mode with voice over LTE. going better couple of days now again called my wife ring ring ring, she picked up and i got network failed! had to call twice again. She is at home on wifi voice over wifi, me out on mobile network over voLTE.

i cannot imagine journalists or who really really needs encryption being frustrated with dropping calls and not answering so you never know of the other end answers or is just the connection that sucks.

one last thing, even if bad signal whatsapp always connects even crappy video but usually goes through. why cant signal too?

thank you

Just want to mention a very similiar issue. I'm on Wifi, 4 meters from AP away, no obstacles inbetween, so best signal. Try calling another phone, immediately "Network failed". Tried again, no calling worked. Had this several times today when testing call function.

Hey Folks, thanks for sticking with us. We recently pushed some fixes and hopeful changes to calling in the latest 5.6 beta.

I'm hopeful it'll fix some issues for some of you but I believe gremlins are still lurking in calling. So, after updating to the beta, if you are still encountering the issues above please provide updated debug logs and anything interesting about your calling situation. Examples of things that are interesting: phone has non-standard hardware (like no camera), using bluetooth, in a region that has internet restrictions, using a VPN, etc.

I can confirm that if installed to both phones, v5.6.2 (80702) solves the issue I previously submitted . Thank you devs!

Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?
