Description:Another problem connecting Asterisk with a Nortel CS2K, which sends "empty" reINVITEs when it wants to stop hold.

At some point, the chan_sip code states:
"/* Some devices signal they want to be put off hold by sending a re-invite
*without* an SDP, which is supposed to mean "Go back to your state"
and since they put os on remote hold, we go back to off hold */"

This patch actually makes it work with 1.4.23.1
