I have registered my account with freshphone, and I am currently using it with the Zoiper Android app.
I have received 2 calls, that worked perfectly, but a subsequent 2 calls where the caller could not hear me besides a very mumbled "gurgle" as it was described.
All 4 calls were minutes apart, and all while the handset was connected to my 100mb fiber line.
The phone is a Samsung S7 edge if that helps.
Oh, Just an additional comment when I phone someone using the exact same application and setup from whithin the app they still can't hear.
I hope you are well. Please check the settings on your LTE router. Look for SIP ALG which should be disabled and also set your firewall settings to low.
Hi I've done that it's worse now no calls can go out even, ps the problem was also when I'm not on this site also.
Please try using your mobile data as an internet source and then test the application.
Ok It seems that has resolved the issue now
Hi No it's back, with a vengeance, totally unusable
Was the issue fixed when you used your mobile data?
Are you still experiencing this problem?
It may be Codec related, ensure you are using either G729, iLBC, or Opus with the App on your phone, this can also happen if your Fibre line dropped slightly or was over utilised by other devices or applications (Streaming or update perhaps. )
Thank you for your reply, I have all the codecs checked.
It seems as if I need to put the person on hold for 1s to get the "under water sound" away. This was tested over 2 different fiber lines as well as over LTE.
I will try each codec individually to see if they work.
This is most likely a codec issue, if you can select g729 on your device, then please choose that one.
i have the same issue above, can make and receive calls buy the cannot hear the incoming caller or when i call out they cannot hear me. I use a yealink phone
You can try to do an "echo test" by dialing *99
Hi I'm having exactly the same problem I can hear perfectly but the person on the other side can't hear anything. When I do the *99 test I can't hear anything except a slight swishing sound. What do I do now? Samsung S5.
