3 endpoints(620154,620155,620156) behind NAT register to  SBC behind a NAT .

Endpoint 620156 supports multiple lines at the same time .

First using Endpoint 620154 to call 620156  at line 1 which is successful, then  using  endpoint 620155 to calls 620156 at line 2 which is failed.

the  sipmsg.log shows that SBC originate a "503 Service unavailable" to  SIP Server when receiving the INVITE .
