Sangoma A108 and libss7/chan_ss7 issues

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Anton, Paul, Joseph,

Thanks for your assistance and suggestions to date.

Based on the information you provided, I think I may have narrowed the source 
ot the problem down the the timing source.

I have my end of the link set as NORMAL in the Sangoma config and Zaptel 
config. This is obvious for me in a Q931/PRI context but I'm not sure how 
signalling works on an SS7 context.

Is SS7 similar to PRI in that I need a master timing source? Can I ask you 
folks how you have set up you timing?

My Zaptel config is:

#Sangoma A108 port 1 [slot:4 bus:13 span:1] <wanpipe1>

span=1,0,0,ccs,hdb3,crc4
bchan=1-31

And the wanpipe1.conf is below.


Thanks again,
Barry
