Fix InCall UI display issue for SIP and normal calls

The SIP Account id was not recognized when the SIP server
doesnt have the "sip" keyword in its id. Due to this, SIP
Incall UI is displayed even after normal call is answered
during a SIP call.

Replaced the pattern "sip" to "@" to recognize SIP acct ID
