[asterisk-ss7] chan_ss7 cluster config.c segfault

[Amish]

Hi,

I also could not get the cluster function in 1.4.3 to work - segfault.
Managed to get further with 1.3 and had it up and running on both hosts 
but had asterisk crash on one of the hosts after a few minutes.

I am now using mtp3d running on both hosts. Will post config later today.

Best Regards,
Amish
