For best results consult following draft: http://www.ietf.org/internet-drafts/draft-ietf-sip-outbound-08.txt However, I am not sure how many devices already implemented it.
I saw 2 different implementations which seem to work well in a real world: 1. Server shortens registration expiration to around 1 minute. Clients frequently register with the server. 2. Use OPTIONS method. Since text parsing is rather expensive, it is easier to create a SIP request. Every once in a while server sends out an OPTIONS request. Processing a response should be much faster than processing a REGISTER request.
