[asterisk-r2] Invalid Cas

[hernan salvarezza]

Hello list,

I am working on Asterisk/R2 and getting the following message:


[Mar 29 18:16:23] ERROR[23776]: chan_dahdi.c:4107 dahdi_r2_write_log: Chan 118 - Protocol error. Reason = Invalid CAS, R2 State = Idle, MF state = MF Engine Off, MF Group = No Group, CAS = 0x04 DNIS = , ANI = , MF = 0x20

This is the short output of mfcr2 show channels:
 
  111 AR      10      14       Yes       No               IDLE     IDLE
 112 AR      10      14       Yes       No               IDLE     0x04
 113 AR      10      14       Yes       No               IDLE     BLOCK
 114 AR      10      14       Yes       No               IDLE     BLOCK

...
 118 AR      10      14       Yes       No                                                 IDLE     0x04


I have searched Google, found an old patch(tried patch and latest openr2), but nothing else.
Do you guys know what "INVALID CAS" means?

Thanks in advance, regards
Hernán
