[SIP Beyond VoIP] sip-subscribe-presence|mwi 'unsupported transport: tcp'

[Juha Heinanen]

Next I tried sipclients_3.0.0jessie_all.deb.  sip-register works always.
sip-subscribe-presence and sip-subscribe-mwi work sometimes, but most of
time complain about 'unsupported transport: tcp'.

I have defined tcp transport like this:

      +-- always_use_my_proxy = True
sip --|-- outbound_proxy = 192.98.102.10:5060;transport=tcp
      |-- publish_interval = 3600
      |-- register = True
      |-- register_interval = 3600
      +-- subscribe_interval = 3600
