2901 voice gateway delay

I have 2 2901 routers connecting an Alcatel to an Asterisk PBX over IP.

With the Asterisk PBX connected directly into the Alcatel, calls are perfect but when the routers are in the loop there is a noticable delay in speech

I have attached the below call brief log - Are the delays here too high? - what does lost mean?

The routers are connected via single mode fibre running at 1Gbps
