Summary:                    Incomming rfc2833 DTMF is not relayed via SIP INFO
method
Description: 
Please bare with me and excuse my ignorance as I am not a Asterisk Guru.

All digits of incomming rfc2833 DTMF signaling are recognized correctly
(as far as  I can tell). The problem is that Asterisk seems to be relaying
the DTMF to the destination as is (rfc2833) instead of sending SIP INFO
messages.

Thanks and sorry for not being more specific. The CSN peer does not have a
user plane and can therefor not recognize DTMF signals in RTP packets,
hence 404 not found. What it needs to receive after the invite is seperate
SIP INFO messages with DTMF content. Simillar to this:

INFO sip:2143302100 at 172.17.2.33 SIP/2.0
Via: SIP/2.0/UDP 172.80.2.100:5060
From: <sip:9724401003 at 172.80.2.100>;tag=43
To: <sip:2143302100 at 172.17.2.33>;tag=9753.0207
Call-ID: 984072_15401962 at 172.80.2.100
CSeq: 25634 INFO
Supported: 100rel
Supported: timer
Content-Length: 26
Content-Type: application/dtmf-relay
Signal= 1
Duration= 160

I was asuming that this what asterisk does in dtmfmode=info. Of course I
might be totally wrong.

Your help is highly appreciated.
