É problema de clock.

Verifique se o resultado do comando "dahdi_test -vvv" ou "zttest -vvv"
está assim:

Opened pseudo zap interface, measuring accuracy...

Se houver uma variação grande nos valores acima, você deve (i)
verificar se o servidor não tem um problema de barramento, (ii)
compartilhamento de IRQ, (iii) sem aterramento ou atterramento
incorreto e (iv) se o Dahdi/Zaptel está corretamente configurado para
sincronizar com o clock da operadora.
