我在使用PJSIP时遇到了问题，被叫听到了我的声音，但我完全保持沉默
少数指针：
1） Chan_SIP运行完美
2） PBX和电话在同一个网络上（没有NAT）
3） 该问题仅发生在PRI上的传出呼叫上（使用IAX2中继时没有问题）
4） 当我通过AMI发起呼叫时，不会出现此问题
5） Asterisk版本-13.4.0 Freepbx版本-6.12.65-26 PJSIP版本-2.2 DAHDI版本-2.10.0.1
我知道PJSIP是实验性的，但我以前已经能够在PRI上使用PJSIP了
可能是什么问题
更新（2015年7月13日）：
由于字符限制，我不得不删除以前的更新和日志中的许多行，但这应该无关紧要，因为问题发生在拨号后（没有拨号音）
从800分机打电话给我自己（替换了我的号码和出站cid）。以下是星号verbose和rtp调试日志：
