[OpenSIPS-Users] SIPv6 UA can't receive a 423 (Interval Too Brief) response from openser-1.3.4-12.fc13.i686 SIPv6 Registrar Server when expiration of a REGISTER request is less than a registrar-configured minimum

[Bogdan-Andrei Iancu]

Hi,

OpenSIPS does not reject the REGISTERs with expire not fitting the min - 
max interval, but simply adjust (as per RFC, a registrar can do that) 
the expire value to fit the configured interval.

As you can see, the "30" value is replaced with 200 OK with "60" seconds.

Anyhow, 1.3 is really old version, I strongly recommend to upgrade to 
1.6 version

Regards,
Bogdan
