[AsteriskBrasil] problema com redfone e E1 embratel

[Alejandro Flores]

Amigos,

Configurei um redfone + link E1 da embratel (ISDN), porém não consigo
efetuar chamadas. O pessoal da Embratel ja testou e efetuou ligações
pelo link, indicando que o link está ativando, roteando, etc...

O E1 levanta, status OK:

ipbx*CLI> pri show spans
PRI span 1/0: Up, Active

ipbx*CLI> dahdi show status
Description                              Alarms  IRQ    bpviol CRC4
Fra Codi Options  LBO
Dynamic 'ethmf' span at 'eth0/00:50:c2:  OK      0      0      0
CAS Unk           0 db (CSU)/0-133 feet (DSX-1)

Se eu ativar o debug:

ipbx*CLI> pri set debug on span 1
Enabled debugging on span 1

A seguinte mensagem não para de subir na tela:

PRI Span: 1 TEI=0 Got SABME from network peer.
PRI Span: 1 TEI=0 Sending UA
PRI Span: 1 TEI=0 MDL-ERROR (F): SABME in state 7(Multi-frame established)
PRI Span: 1 TEI=0 Got SABME from network peer.
PRI Span: 1 TEI=0 Sending UA

PRI Span: 1 TEI=0 MDL-ERROR (F): SABME in state 7(Multi-frame established)

E fica se repetindo o tempo todo.

Ativando o intense debug:
