[asterisk-users] WaitExten() always times out

As far as I can tell Asterisk recives media perfectly. For outgoing calls it
looks something like this:

    -- Executing [xxx at proxy:5] WaitExten("SIP/voiptrunk-00000083", "7") in
new stack
DEBUG[28557]: rtp.c:1032 process_rfc2833: - RTP 2833 Event: 00000001 (len =
DEBUG[28557]: rtp.c:880 send_dtmf: Sending dtmf: 49 (1), at xx.xx.xxx.x

On incoming, as far as I can tell, Asterisk does not recieve anything. I
just don't know why.

I have added exceptions in firewall and network to allow voip traffic,
successfully allowing incoming and outgoing calls. Just no DTMF on incoming

My tests consist of a regular landline, I dial a DID and successfully reach
my asterisk box. Everything is fine until I come to user input. None is
recognized. I get a "-User entered nothing" and timeout.
