[android-developers] Re: SIP Stack

i saw this in sipdroid project FAQ:

"Sipdroid now uses TCP for the signaling connection and keeps the
corresponding port open."

does anyone know how peer servers of sipdroid handle scalability when
there are a million of sipdroid clients connecting with the servers
using TCP?

as i observed, T-mobile Intermittently changes IP of my G1 phone
without any notice, which in fact tears down the TCP connection.
