simbox very bad quality

Hi,

I have configured a simbox connected with a BRI interface. Config:

interface BRI0/1/1

description SIMBOX

no ip address

isdn switch-type basic-net3

isdn overlap-receiving

isdn tei-negotiation first-call

isdn point-to-point-setup

isdn incoming-voice voice

isdn send-alerting

isdn sending-complete

isdn static-tei 0

isdn skipsend-idverify

The customer notices very bad quality and call drops. What can I do to make sure the quality is good and calls are not dropped? We use the same simbox for other customers, but they don't have any problem with it.

Greetz,

Wouter

Bring the issue to the simbox vendor then.
