[asterisk-ss7] Link getting out of service

[Peter Smith]

Hello all,

I am trying to set up a SS7 link with a system in a test scenario. The link is going up in Service and I can see some MSU traffic, SLTM but I can not see any SLTA packets. I can not understand why the SLTM packets are not answering. I post the console debug here:
