Errors on a SS7-Link with libss7

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have the same issue.

- All CIC are "Out of service"
- SS7 is up "SS7 linkset 1 status: Up"
- Incoming calls don't have audio.
- incoming calls produce the following ss7 debug information:

Unhandled optional parameter 0x37 'Unknown'
[0x2 ]
Unhandled optional parameter 0x8 'Optional forward call indicator'
[0x80 ]
Unhandled optional parameter 0x3 'Access Transport'
[0x7d 0x2 0x91 0x81 ]
Unhandled optional parameter 0x31 'Propagation Delay'
[0x0 0x8 ]
Unhandled optional parameter 0x3f 'Location Number'
[0x84 0x97 0x53 0x2 ]
Unhandled optional parameter 0x39 'Unknown'
[0x37 0xc0 0x31 0xc0 0x3f 0xc0 ]

- outgoing calls produce the following errors:

[Jul 31 15:21:55] ERROR[1971]: chan_zap.c:8904 zt_ss7_error: !! Unable 
to handle message of type 0x2e
[Jul 31 15:21:55] ERROR[1971]: chan_zap.c:8904 zt_ss7_error: Received 
error from mtp3 layer: -1

The setup used 2 E1 with signalling on channel 1 of first E1. CICs are 
numbered starting from 1, using channels 2-31 on first E1 and the 
channels 32-62 which are on second E1.

Best regards,

Marc
