I am a new user FreeSWITCH. I found a flaw in the system right after installation to make a call handover between 3 SIP extensions. Example: Extension 1 Extension 2 calls. 2 extension meets and press the "Hold" button. Extension 2 press the "transfer" button, and dials the number of the extension 3. Extension 2 and Extension 3 communicate. Extension 2 press the "transfer" button again to complete the transfer of extension 1 to extension 3. Pressing the "transfer" the extension 2 comes out link. Now Extension 1 and Extension 3 are communicating connection with the extension 2. But in Extension 1 and Extension Display 3 appear as if they were communicating with Extension 2 (no longer part of the link). After transfer to the Station 1 does not have any indication be communicating with the Station 3? After the transfer of the branch line 3 does not have any indication be communicating with Extension 1? How can I fix this problem? My FreeSWITCH is installed on a Debian machine 8-Jessie at: / usr / local / freeswitch. I use the internal settings of extensions 1000.xml to 1019.xml. Thank you for your attention right now!
