[asterisk-r2] Channel Locked

[Alexander]

One or two times a day, I get this message:

[2012-05-22 16:06:57] WARNING[18792] chan_dahdi.c: Chan 36 - Seize Timeout
Expired!

[2012-05-22 16:06:57] ERROR[18792] chan_dahdi.c: Chan 36 - Protocol error.
Reason = Seize Timeout, R2 State = Clear Forward Transmitted, MF state = MF
Engine Off, MF Group = Forward MF init, CAS = 0x00

DNIS = 92245134, ANI = 8152, MF = 0x20

[2012-05-22 16:06:57] ERROR[18792] chan_dahdi.c: MFC/R2 protocol error on
chan 36: Seize Timeout

 

After this the channel, at this case 36, cannot dial until I restart
asterisk.

 

Every time i try dial to this channel i get: 

[2012-05-22 16:07:00] ERROR[16337] chan_dahdi.c: Chan 36 - Trying to dial
out in a non-idle channel (cas=0x00)

 

What I can do?
