Alcatel Unleashed

Dears all,

I have a small problem with transfer out coming calling,
When a call comes from outside to attendant internal, calling is coming. But when I want to transfer this call to another extension, I lose the outside call, and but the transfer to extension coming well.

All phones are Analog type
my Pbx is OXO Large

thank for Help

any adv

Please check flash hook setting on analog phone, DIP switch have setting for 100/300/600 ms. If phone setting is 600 but OXO flash hook timing is 100 then the external call will be disconnect.
