| Description: | A deadlock can occur when a POTS phone tries to flashhook for 3-way calling or transfer. If another process is scanning the channels container when the POTS line flashhooks a deadlock will occur. Found while testing the patch for ASTERISK-16711. While a 150 local channel chain is attempting to optimize out the local channels in the call, do a flashhook to transfer the call. | ||
