- SIP retransmission problem

[Paolo De Michele <paolo@xxxxxxxxxxxxxxxxx>]

Hi all,
I have a problems with asterisk
I configured a number eutelia for so I ring an internal

the file is as follows:


# sip.conf

Register: 0707732332:xxxxxxxx@xxxxxxxxxxxxxxx/0707732332
registertimeout20
registerattempts10

[eutelia]
type=friend
Xlanguage=it
context=from-eutelia
host=voip.eutelia.it
dtmfmode=rfc2833
directmedia=no
fromdomain=voip.eutelia.it
fromuser=0707732332
defaultuser=0707732332
insecure=invite
qualify=yes
secret=xxxxxxxxxx
disallow=all
allow=ulaw
allow=alaw

# extensions.conf

[from-eutelia]

exten => 0707732332,1,NoOp
same => n,Dial(SIP/1000,45)
same => n,Hangup

from cli:

Using SIP RTP CoS mark 5

the call drops after 4-5 seconds
can you tell me what do I go to edit why this doesn't happen?
I also disabled iptables in order to avoid any problem (although it seems properly configured)

Thanks in advance
