Thanks everyone for the valuable inputs... much appreciate.
Correct me if I m wrong...
- Use "chan_ss7" if only 1 signaling link available.
- User "libss7" if multiple signaling link available.
I have four TE420 T1/E1 cards and I'm planning to use two server with
two cards each... I guess I have to verify with the Telecom on how many
signaling link they are going to provide, correct?
Once again thanks for the info... Have a nice weekend.
Cheers,
Nitesh
