[asterisk-ss7] asterisk-ss7 Digest, Vol 111, Issue 2

[Vallimamod Abdullah]

Hi,

Your initial request to not send SLTM looks solved. Now, you are receiving SIOS (out of service indication) from your provider after the link is in service:

> indication 'OS' while INSERVICE on link 'l16’.

> indication 'OS' while INSERVICE on link 'l1’.

The best way to debug this would be to test with just one link to start and ask your provider what they are seeing on their side.
There are many possible causes (hardware echo cancellation, clock synchronisation…) It’s impossible to guess.

Post your full hardware specs and configs on the list and maybe someone will spot the problem.

Please always answer to the list, not to me directly.

Best Regards,
Vallimamod
