HDLC ERRORS on Elastix 1.5.2 + D110P

Hello

We have some HDLC errors on the Asterisk Server.

ELASTIX: 1.5..2
Openvox D110P

The LED in de card is fixed on green.

Telco:
PRI PCM31C - E1. The connection is with the included balun BNC-RJ45


My telco provider has tested de E1 and they tell me that all is OK and this errors maybe a problem on the asterisk configuration or an error in the Openvox Card.

This is my files configuration:

Best regards!

Please ask your telco whether the E1 line have CRC4, if not please modify the system.conf like this:

span=1,1,0,ccs,hdb3#,crc4

# termtype: te
bchan=1-15,17-31
dchan=16
echocanceller=oslec,1-15,17-31



# Global data

loadzone = es
defaultzone = es


regards!
dennis.den

My telco tell me that we have the crc4 activated,... but I tested the E1 without the crc4 using your config file

But we still have this errors...
