我在我的路由器 openwrt 中进行了设置，并尝试使用我为其提供的路由器检索到的提供商的 VOIP 设置来执行呼叫。我的网络设置如下：
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'
config device 'wan_dsl0_dev'
option name 'dsl0'
option macaddr XX:XX:XX:XX:XX:XX
config atm-bridge 'atm'
option vpi '1'
option vci '32'
option encaps 'llc'
option payload 'bridged'
option nameprefix 'dsl'
config dsl 'dsl'
option annex 'b'
option ds_snr_offset '0'
option line_mode 'vdsl'
option tone 'auto'
option firmware '/lib/firmware/vr9-B-dsl.bin'
config device
option name 'br-lan'
option type 'bridge'
list ports 'lan1'
list ports 'lan2'
list ports 'lan3'
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'
如您所见，voip 使用 vlan dsl0.837。另外，我也像这样配置了 siproxy：
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
然后在通过以太网连接到 LAN 的我的计算机中，ekiga 配置如下：
但是，尽管成功连接到 VoIP，我仍无法拨打手机（我的提供商通过 SIP/VOIP 提供固定电话）。我的提供商是希腊的沃达丰。
我尝试呼叫sip:^my_cellphone_number^@192.168.1.1（路由器的IP），但我无法这样做。那你知道为什么吗？
我的防火墙设置也如下：

我还需要打开额外的端口吗？
