requested information.

These are messages from the switch:

Msg:(E_SS7SS_MTP3_SLTM_FAILED) - SLTM failed. [Link : 160, OPC : 0x3e8, 
DPC : 0x708], Cause: SLTA_NOT_RECVD
Msg:(E_SS7SS_MTP3_SLTM_FAILED) - SLTM failed. [Link : 160, OPC : 0x3e8, 
DPC : 0x708], Cause: SLTA_NOT_RECVD
Msg:(IPCC_LOG_ERR) - MTP3:: DISC: INVALID POINTCODES IN INCOMING MESSAGE 
WITH LPC 0x708,RPC 0x3e8. DISCARDING...

It seems that SLTMs are not answered correctly?! And the last message is 
IMHO very confusing...
