[Spce-user] suddenly some inbound calls start failing

[Matthew Ogden]

I see sercmd doesn't have htable.remove?

How would i delete entries from the ipban list of the hash table?

Kind Regards

>From the infos you provided I've no idea what's the scenario you're trying
to solve and what's going on, but there are two (different) things I can
spot:

1. User "wisi4 at 62.175.230.3" gets blocked and banned during Registration,
either because it floods the system with too many requests, or because it
fails to authenticate and tries too often. Check it with "ngcp-sercmd lb
htable.dump auth" and "ngcp-sercmd lb htable.dump ipban".

2. The trace you attached says "404 Not found", or more precisely the
Invite being sent to sip:951057100 at 62.175.230.6:5060 is rejected with 404,
so the user 951057100 at 62.175.230.6 doesn't seem to exist on this "Epygi
Quadro SIP User Agent/v5.3.3 (MIDIGW)" server/gateway (if it's a PSTN
gateway, then maybe the number you're sending is incorrect).
