VoIP 電話遺失從外部 SIP PBX 的註冊

VoIP 電話遺失從外部 SIP PBX 的註冊

這一直是個痛苦。我的 Polycom VoIP 電話（大約 10 部）每隔幾個小時就會失去註冊。每次我檢查它們時，有些會被註冊，有些則不會。重新啟動防火牆可以在幾個小時（4-5 小時）內修復該問題。

我正在使用 pfsense。電話設定為每 180 秒重新註冊一次。

我可以做什麼來解決這個問題？

-謝謝

我目前也遇到同樣的問題。

確保您已完成以下操作：

RTP

For this you will need the ports you setup in step 1.a above. I will be using my
port configuration. Add a NAT rule for RTP. This is essential or you will have
no audio or one way audio in your calls. Also change the NAT IP to whatever your 
Asterisk server is and change the description to something that makes sense for you.

Interface: WAN
Protocol: UDP
External port range: From: 10000
External port range: To: 20000
NAT IP: 192.168.1.50
Local Port: 10000
Description: Asterisk PBX - RTP
Enable Auto-add a firewall rule to permit traffic through this NAT rule

SIP

For this you will need the ports you setup in step 1.a above. I will be using my port
configuration. Add a NAT rule for SIP. This is essential or you won't be able to receive
calls and you may have trouble registering with your SIP provider. Also change the NAT IP
to whatever your Asterisk server is and change the description to something that makes
sense for you. 
Code:

Interface: WAN
Protocol: UDP
External port range: From: 5060
External port range: To: 5060
NAT IP: 192.168.1.50
Local Port: 5060
Description: Asterisk PBX - SIP
Enable Auto-add a firewall rule to permit traffic through this NAT rule

並且還禁用連接埠重新映射

Click Firewall -> NAT, and the Outbound tab. Click "Manual Outbound NAT rule  
generation (Advanced Outbound NAT (AON))" and click Save. 
You will then see a rule at the bottom of the page labeled "Auto created rule for
LAN". Click + to copy that rule. Change the rule so it only covers the source IP of
your device that needs static port, and any other settings you need. Check the 
"static port" box on that page, and click Save. 
Move the rule to the top of the list. Apply changes and this behavior will be disabled.

如果以上方法都不起作用，您也可以在 pfSense 上安裝 SIP 代理守護程序
