The SIP protocol is used heavily for attacks from the Internet.
As counter measure, OpenScape Office V3.2 and HiPath 3000 V9 have implemented a number of security mechanisms including the blocking of unknown peers.

External SIP communication e.g. with ITSPs is only possible via IP addresses and ports known to the system. If different servers are used by the ITSP, they have to be communicated via DNS-SRV to the SEN platform. If this is not done by the provider, the workaround described in the following document may be used.
