[asterisk-ss7] SS7 link setup between Telsis and Asterisk

[Deepika Nijhawan]

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]

language=en

 

; Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" (MASTER)

group=0

context=from-pstn

signalling = ss7

ss7type = itu

linkset = 1

pointcode = Asterisk PC

adjpointcode = Telsis PC

defaultdpc = Telsis PC

networkindicator=national

cicbeginswith = 1

sigchan = 16

channel=>1-15,17-31

 

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