PAP2 No Audio.

Unanswered Question
Jun 19th, 2009

Customer has the following setup:

DSLmodem<><><><><>NETGEAR Router<><><><>PAP2<><><><>Two Analogue Phones.

Customer has subscriber information correct.
Has latest version 3.1.23


Cannot hear anything when making internal calls, no audio on both only dial tone.
When making outbound calls again he cannot hear his clients, however the client can hear customer in a very low tone of voice.

Any ideas to what could be the issue? is it QoS? Thanks in advance.

I have this problem too.

Hi Juan,

Has the device ever been configured and worked in this environment before, or is this a new installation?

How is customer attempting to make internal calls, please describe in detail?

Do inbound calls work without problem?

I doubt the issue is related to QoS. QoS usually results in choppy audio, also called jitter.

Does the customer have  a firewall enabled? If so, please disable and test for one-way audio again.

One-way audio is usually related to NAT and or SPI firewalls that don't allow the seemingly unsolicited RTP through.

Regards,

Patrick
