[asterisk-ss7] Problems setting up cluster with chan_ss7

[asterisk at nicox.org]

Hello,

I have a little bit different implementation to do, but its not working, 
also there is a problem with oneway traffic and after some days there is 
no chance to get traffic over it.
I tried it with chan_ss7 0.9 and 8.4, but alwas the same problem, for me 
it looks like that there is a cache in Zaptel or something like this, 
which is full and its not working.

Can you write some details of asterisk/zaptel/chan_ss7 versions you use? 
did you tried to make a bit more calls for a week or so on?

Thanks

Nico
