Hi,

I’m trying to configure osmo-bsc to connect to an IPA based MSC and get a
failure when activating the sigtran stack.

Here’s the log:

root at sysmobts-v2:/etc/osmocom# osmo-bsc -c /etc/osmocom/osmo-bsc.cfg
<001d> ../../git/src/osmo_ss7.c:1269 0: ASP Restart for server not

<0005> ../../../git/src/osmo-bsc/osmo_bsc_main.c:504 Failed to initalize

I used the configuration posted by Harald part of ticker
https://osmocom.org/issues/2544
https://osmocom.org/attachments/3154/osmo-bsc.cfg.ipa
and get the same result.

How can I troubleshoot further in order to know what’s happening?

Best regards

Roch.
