FPL - Can not hear other side

Post by leiz_ca »

Have FPL account with SIP unlock code. Tried both windows desktop FPL application, and SIP client on Android phone / iphone, have exactly same issue. I can not hear other side talking while other side can hear mine. Tried wifi / 3G, same result. Try fongo app on iPhone and it works fine with fongo account. Also tried other sip account on Android/iphone and all worked fine. Is there anything I need to setup to fix this? Thanks a lot for any help!

Thanks for the response. It is still not working.

When I try to make the call, I can not hear the ring before the other side pickup the phone. After connection is established, the other side can hear me no problem, while I can only hear silence.

Sounds to me that the audio never reach to my phone (or fpl desktop application). Was suspect the firewall / NAT issue, but switched to different wifi, and different 3G provider (telus, bell, wind) the problem persist.

Im guessing its earthier your wifi router/modem/3g filtering the recommended FPL ports for your telephone to work fully, things like one-way audio etc are usually related to ports being blocked by hardware firewalls. I suggest you to perhaps configure a Static IP for your SIP ATA voip device. Allow the specific FPL ports to be forwarded with the static ip you setup for your SIp ATA device.

Issue resolved. Called ISP and they somehow remotely reset my ADSL modem, then reboot my router, followed by a reboot of my phone. everything seems working. Over 3G it is kind of weird, sometimes it worked but most of the time it didn't. Guess I need to try some other telephone company.

Anyway, I don't think it is FPL's issue and thanks a lot for all the help here!
