[Sip] Non-default SIP port

[Zakaria Gaguk <gaguk_el80 at yahoo.com>]

Hi
I just joined this mailing list so I am not sure if my following questions have been posted.
1. is there any "danger" if a sip UA agent registers with port other than that 5060 (default) port, for example 5062 or any other unassigned ports? 
2. In this case SIP messages for any incoming call to thsi UA will have the UDP destination port defiend as 5062. Is this a correct understanding?
3. General question: when a UA register, is it alwasy assumed that this is only for VoIP?

Thanks
Gaguk
