VoIP audio missing over hotspot for the last 2 days - SIP / RTP troubles

I used my PublicMobile smartphone hotspot to connect another smartphone VoIP app. Worked fine until friday (2024-02-09) morning [used at 10:11 on the 8th]. The connection is established (counter working) but no audio either ways. It works fine over Bell or Videotron wifi. 

What changes did you do ? Did you (or Telus) blocked the RTP ports ?

This morning, I began to suspect the culprit could be the phone Hotspot mode itself. To test that, I put my SIM card in another phone. Although my PublicMobile service is on LTE, I saw 3G in the top screen. I tested and all the phone I add Fongo installed on (since yesterday, many) and I could get a call connected AND WITH AUDIO ! I put the SIM card back in my phone and tested anew as is. Same problem with the audio. I chose the 3G network (rather than letting the phone use the "preferred network"), and tested: all the phone were fine on 3G (connection and audio). I went back to the preferred network (which is LTE), and tested again: everything was fine now. So I suppose there was a glitch during the night (from thursday to friday last) during which the phone automatically switched from LTE to 3G and then back, and some variables values where left set improperly. Do you have another explanation ? (I received the answer 'no idea why this happened'). Any of you think of something ?

I have APN type: default,mms,agps,supl,fota,hipri,dun from a previous debug (last fall, if I remember well). I will try uppercase DUN as default,mms,agps,supl,fota,hipri,DUN right now.

hi @lgpm99 try update APN

APN Type: default,supl,mms,dun

or

APN Type: default,supl,mms,DUN

try both case might be sensitive

I agree sometimes Fongo audio quality is not so good, although on LTE it is fine. Connecting on straight mobile data (I tried that as well 🙂 , works, of course, but I need it to work for a second phone which must connect via hotspot or wifi, and that is no longer working... at least... it works (connect), but no audio... on a phone... is not very practical 🙂 ! I will submit a ticket.

Hi @lgpm99

I find the audio quality very unsatisfied myself

did you try Reset all networks?? Try to use straight mobile data instead of hotspot. try the Fongo on wifi as well

If same, ask agent to help.  please submit a ticket with CS Agent here:

I have been using Fongo for years by now and I am satisfied. I though it could have been a Fongo update at first, that is why I tried many smartphone with many Fongo version before trying to get help from you. They all work fine on Bell and Videotron wifi, but as soon as it connect via PublicMobile, there is no audio. It used to work on PublicMobile last Thursday but suddenly not on Friday morning ! I am not a newby. Something is going on. I also tried to edit a new APN to no avail.

Hi @lgpm99 I would say it is very likely a Fongo problem.  I used Fongo myself too.. it is poor, lots of issue vlwith voice quality even using the mobile data directly ( I used it in Rogers and Telus).  Textnow is way better 

with Fongo, you really need to play around the different codec settings

Or try uninstall and reinstall

Fongo. I tried updating the app, another phone, and so on. It does not explain why the same app on the same phone, is working when I connect to a wifi from other providers (Videotron and Bell) but not on PublicMobile as it used to do. It was sudden: working one day, not the following morning. All I did was sleep, in between 🙂

Of course I tried that among many other things, including reboot.

Hi @lgpm99 

What VoIP app you use?? There are different settings to change , check the settings of the app

I doubt they did @lgpm99 

Try disconnecting the hotspot and trying it again - it should work fine.
