Is RFC 3261 a valid reference?  It’s valid for SIP, but doesn’t describe using ALPN.  In fact, what it says about TLS is that by default, proxies should be listening on port 5061 for TLS, not sharing some common port with other services.

Is there some document that talks about sharing a port between SIP and other services?
