私はルータopenwrtに設定し、指定されたルータから取得したプロバイダのVOIP設定を使用して電話をかけようとしました。私のネットワーク設定は次のとおりです。
config interface 'loopback'
option device 'lo'
option proto 'static'
option ipaddr '127.0.0.1'
option netmask '255.0.0.0'
config globals 'globals'
option ula_prefix 'fdd2:a40d:d919::/48'

list ports 'lan4'
config interface 'lan'
option device 'br-lan'
option proto 'static'
option ipaddr '192.168.1.1'
option netmask '255.255.255.0'
option ip6assign '60'
config interface 'wan'
option device 'dsl0.835'
option proto 'pppoe'
option username 'username'
option password 'password'
option ipv6 'none'
option keepalive '10'
option mtu '1492'
list dns '1.1.1.1'
option peerdns '0'
config interface voip
option device 'dsl0.837'
option proto 'dhcp'
config interface 'wan6'
option device '@wan'
option proto 'dhcpv6'
ご覧のとおり、voipはvlanを使用していますdsl0.837。また、次のようにsiproxyを設定しました。
config siproxd general
# Custom options allow using OpenWRT network names, and defaults should
# work out-of-the-box. If your SIP devices do not REGISTER externally,
# you may also need to open firewall ports: tcp/udp 5060, udp 7070-7089.
option interface_inbound lan
# option interface_outbound dsl0.837
# All other documented siproxd configuration directives are supported. Use
# a UCI 'option' for single-instance directives, and UCI 'list' entries for
# directives that allow multiple instances, per the examples below.
# Define low-level network devices, overriding interface_in/outbound:
# option if_inbound eth0
option if_outbound dsl0.837
# Enable DEBUG logging for configuration messages:
# option debug_level 0x00000100
# option silence_log 0
# Load two plugins: one that logs SIP call details to syslog, and one
# that strips out G.729, GSM codecs:
# list load_plugin 'plugin_logcall.so'
# list load_plugin 'plugin_codecfilter.so'
# list plugin_codecfilter_blacklist G729
# list plugin_codecfilter_blacklist GSM
daemonize 1
masked_host=ngn.hol.net
outbound_proxy_host = ngn.hol.net
outbound_proxy_port = 5060
その後、イーサネットを介してLANに接続されたマイコンピュータでは、ekigaは次のように設定されます。
ただし、VoIPに正常に接続されたにもかかわらず、まだ携帯電話に電話をかけることはできません（私のサービスプロバイダはSIP / VOIPを介して有線電話を提供します）。私のサービスプロバイダはギリシャのVodafoneです。
（ルーターのIP）に電話をかけましたがsip:^my_cellphone_number^@192.168.1.1できませんでした。なぜそれを知っていますか？
私のファイアウォール設定も次のとおりです。

追加のポートを開く必要がありますか？
