SIPQ Info from Unify
With the introduction of the Unify own VoIP stack, HiPath 4000 V6 and OpenScape 4000 V7 do not longer support CorNet-IP trunking in the future. Exception is the IP trunking for the Xpressions system, which is still supported.
The system operator should convert all existing CorNet-IP trunks in the field to SIPQ as with activation of a new loadware, CorNet-IP trunking is no longer supported. (This new LW will be provided with the A2 software line i.e. meaning pzksti40.A2.xxx-yyy). Systems that do not support SIPQ must be upgraded.
From E04/2014 no expansions using the old loadware are allowed. Only SIPQ may be offered and supplied for IP trunking applications.
