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?
Get her to test calls to other landlines. Check that SIP ALG is disabled on her router. If she is using a Yealink cordless phone, the number assignment settings on the base might not be configured correctly to receive incoming calls
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.
Having a issue with this olderly lady i know. Moved her to freshphone but now when she dials 0119995102 the call counts but she cant hear them at all ? The codec are all perfect, she is on fibre and using a yealink phone. What could i try ? But when she calls my cellphone i can hear here etc. Seems to be with certain numbers. Also now im told when she calls the phone it doesnt ring ? Think she might be going crazy
This is most likely a codec issue, if you can select g729 on your device, then please choose that one.
DHCP time should be disabled and then you can use 22.214.171.124 as the time server +2 GMT
Some ISP's, very few, actually require SIP ALG to be enabled.
One way audio is almost always related to the Firewall, but if it works sometimes and then doesn't work, it could be related to the connection to ( if they can't here your) or the connection from (if you can't hear them)
