Asterisk 1.6.2.3 diverted call

I recently installed Asterisk version 1.6.2.3 and run into a weird problem. Everything is working fine except call forwarding. If a call is forwarded and a user answers he can hear ring tone on the background, calling party does not hear this. I have been using version 1.2.12 previously and never experienced such issue before. Does anybody have any ideas what might be the cause?

Recently, you shouldn’t have installed any 1.6.2.x as even security fix support will cease in April, and mainline support has already ceased. If there are strong reasons why you must use a 1.6.2.x version, it should have been 1.6.2.22. Many bugs will have been fixed between 1.6.2.3 and that version.
