[Freeswitch-users] Blind Transfer

[Scott]

Hi list,

Trying to resolve an issue with blind transfers.

When transferring a call, the A leg is terminated if a blind transfer  
is started, an attended transfer doesn't create this scenario.

Here are the transcript logs from FS relating to the event. I have log  
level set to 6 but can increase this if I need more information.

Call flow is as follows..

ext18: Calls ext51
ext18: transfers call to ext15
ext15: rings for a split second
ext51: lands in voicemail of 15
ext18: clears as normal

OS: CentOS release 5.7 (Final)
