ok i have this configuration now
client - asterisk+pjsip (public ip 1.1.1.1)
pjsip/307
pjsip/308

server - asterisk+chan_sip (public ip 2.2.2.2)
sip/307
  Addr->IP     : 1.1.1.1:5060
  Reg. Contact : sip:307 at 1.1.1.1:5060

sip/308
  Addr->IP     : 1.1.1.1:5060
  Reg. Contact : sip:308 at 1.1.1.1:5060


now, every call from server to client  is received through pjsip/307 . 
but i need receive call for pjsip/308 through registration of pjsip/308. 
is it possible?
is it possible configure different source port other than 5060?
