I just want some advice and suggestion regarding latest SIPVicious attacks which happens on an IP Phone. One of my customers is using VoIP service by using an IP phone without using any PBX or any other device as a mediator. We want to enable a setting in the phoneâ€™s configuration for preventing such types of attacks and allowed calls only from the SIP IP address and allowed calls to given IP options. Our phone does not support this type of features.
If you would be able to advise a phone or a possible solution for that customer since they are a very small business who has limited technical experience. Unfortunately this is not in my area of expertise so any further help would be greatly appreciated to this matter.
