I bought this W52P a few months ago and at the start it seemed to be working well until recently nearly every call i answer i cannot hear the caller but they can hear me.
It is really frustrating as i can't seem to find what the issue is. Has anyone any ideas?

Hi,
One way audio -this is what you have- is usually caused by the router.
Please try next to resolve this issue:
Router: Be sure SIP ALG is disabled and forward the proper ports to your W52P.
W52P: Make sure Keep-alive Message is Enabled.

Hi again,
Well i checked my W52P settings and Keep-alive Message is Enabled but unfortunately i don't think i can set SIP ALG to disabled because according to
http://docs.sipcentric.com/article/141-d...ng-sip-alg i can't do that with a Virgin Super Hub Router
Any other ideas?
Hi Steve,
I’m doing my best.
Are the ports 11780-1180 UDP forwarded to the W52P?
Network > Advanced > Local RTP Port
I assume that the volume level of the handset is not too low?
Have you tried the workaround as described in the article? E.g. use port 5065 instead of 5060.
Immediately after you have placed a call and somebody calls you, you have never an issue in audio.
Can you verify this?
BTW: Are you running the latest firmware?
