cornfedsip: voip and sip protocol problems

I'm triing to configure guarddog to open Voip connection with
cornfedsip
I opened UDP 5004 and 5060 and STUN port 3784 but i'm not still able to make a 
call (connection itself works); the reason is in the /var/log/syslog below.

Dec 22 14:33:01 linux kernel: DROPPED IN= OUT=eth0 SRC=192.168.1.2 
DST=195.190.166.249 LEN=200 TOS=0x00 PREC=0x00 TTL=64 ID=7 DF PROTO=UDP 
SPT=5004 DPT=10094 LEN=180

SPT=5004 DPT=10094 LEN=180.

Looking in the guarddog export-script I see the following lines

# Traffic from 'Internet' to 'Locale'
# Allow 'userdefined2'
ipchains -A f0to1 -p udp --sport 0:65535 --dport 5060:5060 -j ACCEPT
ipchains -A f1to0 -p udp --sport 5060:5060 --dport 0:65535 -j ACCEPT
# Allow 'userdefined6'
ipchains -A f0to1 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT
ipchains -A f1to0 -p udp --sport 5004:5024 --dport 0:65535 -j ACCEPT
# Allow 'userdefined1'
ipchains -A f0to1 -p udp --sport 0:65535 --dport 3478:3479 -j ACCEPT
ipchains -A f1to0 -p udp --sport 3478:3479 --dport 0:65535 -j ACCEPT

under "ipchains"
# Traffic from 'Locale' to 'Internet'
# Allow 'userdefined2'
ipchains -A f1to0 -p udp --sport 0:65535 --dport 5060:5060 -j ACCEPT
ipchains -A f0to1 -p udp --sport 5060:5060 --dport 0:65535 -j ACCEPT
...
# Allow 'userdefined6'
ipchains -A f1to0 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT
ipchains -A f0to1 -p udp --sport 5004:5024 --dport 0:65535 -j ACCEPT
# Allow 'userdefined1'
ipchains -A f1to0 -p udp --sport 0:65535 --dport 3478:3479 -j ACCEPT
ipchains -A f0to1 -p udp --sport 3478:3479 --dport 0:65535 -j ACCEPT

but under "iptables firewall"

# Traffic from 'Internet' to 'Locale'
# Allow 'userdefined2'
iptables -A f0to1 -p udp --sport 0:65535 --dport 5060:5060 -j ACCEPT
# Allow 'userdefined6'
iptables -A f0to1 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT
# Allow 'userdefined1'
iptables -A f0to1 -p udp --sport 0:65535 --dport 3478:3479 -j ACCEPT
...
# Traffic from 'Locale' to 'Internet'
# Allow 'userdefined2'
iptables -A f1to0 -p udp --sport 0:65535 --dport 5060:5060 -j ACCEPT
...
# Allow 'userdefined6'
iptables -A f1to0 -p udp --sport 0:65535 --dport 5004:5024 -j ACCEPT
# Allow 'userdefined1'
iptables -A f1to0 -p udp --sport 0:65535 --dport 3478:3479 -j ACCEPT

Why then is not working?

Thank's
