Hi,
I am trying to configure ss7 link between Telsis and Asterisk. I am using
WHITE BOOK ISUP user part on Telsis. But link is not coming up. I am getting
below errors:
[May 18 11:19:08] ERROR[23463] chan_dahdi.c: Received MSU in invalid state
1
Enabled debugging on linkset 1
Link state change: NOTALIGNED -> IDLE
Link state change: IDLE -> NOTALIGNED
Len = 4 [ ff ff 01 00 ]
FSN: 127 FIB 1
BSN: 127 BIB 1
>[0] LSSU SIO>
My config files are below:
/etc/dahdi/system.conf:
# Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER)
span=1,1,0,ccs,hdb3,crc4
# termtype: te
bchan=1-15,17-31
mtp2=16
#echocanceller=mg2,1-15,17-31
/etc/asterisk/chan_dahdi.conf:
[channels]

context=from-pstn
signalling = ss7
ss7type = itu

pointcode = Asterisk PC
adjpointcode = Telsis PC
defaultdpc = Telsis PC
networkindicator=national
cicbeginswith = 1
sigchan = 16

Could anyone help me out please ? Maybe I am missing something in
configuration.
