Configure:

network-clock-participate wic 0

network-clock-select 1 t1 0/0/0

Also make sure PBX is providing clock.

If that not the case, remove clock select and configure clock source internal under controller T1.

[3640]

clock source is internal

[2811]

clock source is internal

and

i configured "network-clock-participate wic 0"

is need config of "network-clock-select 1 t1 0/0/0" ?

Not with clock internal.

The 3640 could be more tolerant regarding clock, it was expereincing many errors anyway, so try clock external, all failing check PBX settings again.
