[asterisk-ss7] libss7 - two linksets with different DPCs but the same CIC Number

[Gregory Massel]

I believe that the question was around one linkset with two DPCs and the 
same CIC number range.
chan_ss7 refers to this as "combined" linksets and it does NOT support 
combined linksets with the same CIC range on each link.
It gets all confused when trying to check for idle cic's and free cic's 
back to the idle list as it doesn't match both the CIC and DPC, only the 
CIC.

It will work if the linkset is not combined, however, if you receive 
signalling from an STP via the one signalling link in respect of CIC's 
related to the other link, it will get confused and such an installation 
is quite common where there is an STP on the other end.

By contrast, libss7 handles this situation perfectly.

PS. Not knocking chan_ss7; it's great. Just saying that, for the 
situation described below, it will not work properly.
