Loading huge amount of records from mysql takes time indeed. Maybe prefix matching will be added in redis in the future, or scripted server side in lua, as I understood it has such feature. Another option would be to add a custom command in kamailio like redis_cmd_pmatch() to do internally these prefix-based commands until a match, could simplify the config if it becomes something very popular. Also, I forgot about the other solution in kamailio - pdb module written by 1&1 for number portability: * http://kamailio.org/docs/modules/stable/modules/pdb.html Just mentioning it here for let it be known, if redis is working fine for you, makes no sense to look for other solutions.

CAcert root in Lumicall
by Daniel Pocock 17 Feb '12

17 Feb '12

I've been contemplating Daniel's earlier question about using the CAcert certificates with Lumicall sip5060.net should already accept mutual authentication from other Kamailio instances running with a CAcert certificate However, the Lumicall dialer itself will only connect to servers that are using a cert signed by a root CA trusted within Android. This applies to both the SIP and STUN over TLS support. It may be possible for me to embed the CACert root in the Lumicall package and create a … [View More]
