asterisk users - Dec 2008 - Asterisk Problem chan_sip.c: Call''from''to extension rejected because extension not found.

Hi All, how are you?
I would like to know from you if the problem can be below is a BUG of
the asterisk-1.4.21.
I did an upgrade version of asterisk-1.2.18 for the version of
asterisk-1.4.21 and now, when users try to sip friend outgoing calls
through Polycom IP 330 appliances can not be the traditional way or
with the telephone handset in his hand and digit dialing digit to
receive the following information in the CLI asterisk:
chan_sip.c: Call''from''to extension rejected because extension
not found.
Example:
[Dec 12 10:05:44] NOTICE [23,330] chan_sip.c: Call from'19703
'extension to'00' rejected because extension not found.
[Dec 12 10:05:47] NOTICE [23,330] chan_sip.c: Call from'19703
'extension to'00' rejected because extension not found.
[Dec 12 10:05:49] NOTICE [23,330] chan_sip.c: Call from'19703
'extension to'00' rejected because extension not found.
And sending all digits at once the connection is completed successfully.
The following is the configuration of sip friend:
[19703]
type = friend
context = DLD
Secret = XXXXX
host = dynamic
dtmfmode = rfc2833
regexten = 19703
CallerId = "19703" <19703>
callgroup = 25
pickupgroup = 25
nat = yes
amaflags = billing

Could you help me?

Best Regards

Josue

The short answer to your question is "1.2 and 1.4"

The longer answer is "Read this security release from March of this  
year, which is what the FBI was talking about:
http://downloads.digium.com/pub/security/AST-2008-003.pdf
"

The even longer, but more complete answer is:
