linux (CENTOS 6.2) 上的 Asterisk PBX 掛斷 33 秒後正在錄製的呼叫

我通過在 linux CENTOS 6.2 上執行的 ASTERISK PBX 撥打電話時遇到問題。

案例是從 /var/spool/asterisk/outbound/ 觸發呼叫

呼叫者被撥打撥號計劃執行：

Answer()
Wait(1.5)
Set(Timestamp=$<someformat)
Record(.../<filename>.wav,0,0,y)
HangUp()

我的 SIP 中繼提供商是 nextiva。我從 Wireshark 跟踪中註意到的是，nextiva 就在呼叫被掛斷之前發送了一個 SIP: BYE 請求。

我攻擊了wireshark跟踪以供參考：

其他人有熟悉的問題嗎？

在像這樣從下游發送 BYE 的情況下，我總是向我的提供商開一張票，並詢問他們為什麼發送 BYE。很多時候，他們需要使用另一家 ULC（基礎承運人）開票才能解決問題。有時它甚至比這更下游。提供您的 CallID 和 PCAP，他們應該可以跟踪它。
