Problems with receiving fax

Hi,

Yesterday I connected a Linksys PAP2T to a fax device so we can fax over Asterisk.
Sending faxes all works fine but I cannot receive faxes.

When sending a fax this is what happens (1314 is an extension with fax enabled):

-- Called 1314
-- SIP/1314-00003b2b is ringing
-- Connected line update to SIP/100-00003b2a prevented.
-- SIP/1314-00003b2b answered SIP/100-00003b2a

== Redirecting ‘SIP/100-00003b2a’ to fax extension due to CNG detection

I see a notice and a warning but am not sure if they have anything to do with this issue and how I should fix them? Maybe anyone can point me in the right direction?

I use Asterisk 1.8 with Freepbx 2.9 (distro).

Thanks in advance,

James
