Asterisk is during 11 seconds to pickup call

Asterisk Asterisk Support
1

I have an Asterisk version 11, but it takes a lot to transfer, make a call and catch a call. But when I talk is ok. It just happen when I transfer, make a call and catch a call is during 11 seconds.

I use and codec g729 in my SPA 8000 Cisco. But why is takes a lot to transfer, make a call and catch a connection?

Please see my CLI

Or this problem can be in my Cisco SPA8000? Or this can be in my Delay or Latency? How can I fix it?
