Description:I'm making a SIP call from a SIP softphone through a SIP GSM gateway.
Because of 6 seconds silence during the connenction through the GSM gateway I'm playing tones. Thats works fine until I try to spy the channel. Then the caller can't hear the callee, the callee can't hear the caller but the spier hears both sides. If the spier stays on the channel and the caller establishes a new connection all works fine.



[out-gsmgate]
EXTEN => xxx, 1, Answer()
EXTEN => xxx, n, Playtones(waitforring)
EXTEN => xxx, n, dial(SIP/gsmgate&Local/s@no-op,60)

[no-op]
EXTEN => s, 1, Hangup()

Not enough information provided. Please include console output, channel configuration information and the entire dialplan required to reproduce this issue.

We'll also need SIP debug information.

Sorry I did a mistake in my discription. Only the caller can't hear the Callee after spying the channel.

I hope you can reproduce it with the uploaded files.

Tested with the latest from Asterisk 11, this does not appear to be broken still.

In the log below, {{SIP/ekiga}} dials a Local channel that spins for a bit and {{SIP/bob}}. {{SIP/bob}} answers. {{SIP/alice}} spies on {{SIP/ekiga}}, and spys correctly.
