[asterisk-ss7] Siemens SDE - libss7

[Claudio Aznar]

Testing with chan_ss7 & Asterisk 1.4, I have INSERVICE with "ss7 link
status" and in the SDE side I look the link up too but don't work. 
Like that libss7, the link go from DOWN to INSERVICE, I attach a little
debug from chan_ss7


sspVoIP*CLI> ss7 link status
linkset siuc, link l1, schannel 16, NOT_ALIGNED, rx: 0, tx: 4/4,
sentseq/lastack: 127/127, total    668544,    668592

sspVoIP*CLI> ss7 linestat 1
Linkset: siuc
CIC   2 Idle Reset pending  BLOCKED Link down
CIC   3 Idle Reset pending  BLOCKED Link down
....
CIC  31 Idle Reset pending  BLOCKED Link down

And I see this WARNINGs & ERRORs

[Jun 29 19:21:35] WARNING[3930]: mtp.c:791 timeout_sltm_t1: No SLTA received
within Q.707 timer T1, trying again on link 'l1'.
[Jun 29 19:21:44] ERROR[3930]: mtp.c:796 timeout_sltm_t1: No SLTA received

[Jun 29 19:21:44] WARNING[3930]: chan_ss7.c:637 monitor_main: MTP is now
DOWN on link 'l1'.

You timing looks good.  That's the biggest thing I was concerned  
about.  I can't remember exactly, it was either a TE4xxp or a TE110P,  
when I tested it, but it was one of the two.  Maybe finding further  
into what that error means could help us.  It's possible that it's  
expecting periodic SLTM messages, which we don't do unless the other  
end does first right now.  But the meaning of that error is what  
ultimately matters.
