I came across a very anoying problem with ChanSpy 'B' option. It doesn't work well. If an outer call arrives in the AST PBX and a SIP exten aswers it the exten channel can not hears the whisper. SIP exten to exten the B option works perfectly.

The CLI show me the two channels are able to hear the whisper, but in fact the SIP/1003 can not hear anything:
Attaching Local/s at whisper-to-participant-0000001e;2 to SIP/1003-00000017
Attaching Local/s at whisper-to-participant-0000001e;2 to SIP/1003-00000017
Attaching Local/s at whisper-to-participant-0000001e;2 to SIP/NeoPhoneX-out-00000016

Here are the CLI messages:
