日志的重要部分是这两条警告消息：
[2012-08-01 09:08:11] WARNING[3921] chan_sip.c: Retransmission timeout reached on transmission [email protected]:5060 for seqno 102 (Critical Request) -- See https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions
Packet timed out after 9983ms with no response
[2012-08-01 09:08:11] WARNING[3921] chan_sip.c: Hanging up call [email protected]:5060 - no reply to our critical packet (see https://wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions).
这表明 Asterisk 向您的 IP 电话发送了一条 SIP 消息，但从未收到回复。因此，它被迫挂断电话。
