[Asterisk-Users] RTP Read error: Resource temporarily unavailable (DTMF Issues)

[Thomas Gallaway]

Hi

I am working on this since a while now and seem to be stuck. Here is my 
issue:

I have a bunch of Budge Tone 101's. Asterisk is set up. 4 Incoming PSTN 
lines.
It all works fine just the DTMF is not working. I am not beind a NAT so 
the phones
can talk directly to the asterisk server.

When I want to check voicemail for example the voicemail box is 113 and 
password is 1111:
    -- Playing 'vm-password' (language 'en')

----------------------------------------------------------------

and so on. Maybe 1 out of 20 tries I can get the password right. The 
same happens with Meetme.
If I tell meetme to use a PIN it wont detect it right.

My sip.conf looks like this for one phone:
[113]
username=113
type=friend
host=dynamic
disallow=all
allow=alaw
allow=ulaw
context=intern
secret=
mailbox=113
dtmfmode=rfc2833
nat=0

My budgetone is set to send DTMF via via RTP (RFC2833) with a payload 
type of 101. (tried 100 and 102)
The first 2 codecs are set to PCMU and PCMA (tried to switch those 
arround too).

Any help very appreciated!

Thanks,
             Thomas
