No audio on outgoing calls; can't receive incoming calls

Postby neptune » 12/07/2017

Hi all,

Have been using FPL for almost 8 years. Just couple days ago ran into problem:

Outgoing calls connect but no audio between callers
Incoming calls don't ring

I've rebooted the ATA but no luck.

Software Version: Program -- 1.0.8.2 Bootloader -- 1.0.0.7 Core -- 1.0.8.2 Base -- 1.0.8.2
CPE --
NAT: Unknown NAT

Proper device reboot sequence is always modem--->router (wait for it to be fully up and running)-->ATA
in that order.

Also double check your settings against the PDF file found at viewtopic.php?f=15&t=18839#p74658 (settings should be somewhat similar).

I also suggest reading the first four pages of the preamble, in particular the sections on SIP ALG and UDP timeouts, located at viewtopic.php?f=15&t=18805#p738396.
The purpose of voip4.freephoneline.ca:6060 is to circumvent faulty SIP ALG settings in routers.

Also try a different phone.

Thanks Liptonbrisk.

Seems my router's SIP ALG setting got reverted back somehow. All good now! :)
