I see sercmd doesn't have htable.remove?

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

Kind Regards

1. User "wisi4 at" 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 is rejected with 404,
so the user 951057100 at 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).
