Summary:                    Unable to change the packetization settings (ptime)
for codecs from default of 20ms
Description: 
Hi, I am currently running Asterisk version 1.4.21
my problem is that even though i have tried to force outbound calls with a
codec packetization rate of 10ms, or 30ms, asterisk keeps sending the
Invite message with the default ptime of 20ms.

my sip.config file for this peer is 

[sylantro]
type=friend
disallow=all                    ; First disallow all codecs
disallow=gsm
allow=ulaw:10,alaw:30           ; Allow codecs in order of preference
autoframing=yes
context=testcontext
trustrpid = yes
;dtmfmode=inband
canreinvite=yes
host=195.219.133.219
port=5065

sip show peer command shows the following settings

Hi, I have tried setting the codec setting in the [general] portion of the
sip.conf file and this seems to do the trick. i get  the required codec
packetization rate in the invite for the Outgoing INVITE. i guess my
problem isn't why the packetization isn't being set, it to do with getting
asterisks to recognize that the outgoing call is going through a peer thats
been setup in the sip.conf and not just an unrecognized peer.
