No, make all 5 be DID lines. This way you can have calls come in on any
line and get it to where you want. Your extensions.conf file would end
up like this.

[incoming]
exten => 1111,1,Goto(CompanyA,s,1)
exten => 2222,1,Goto(CompanyB,s,1)
exten => 3333,1,Goto(CompanyC,s,1)

[CompanyA]
exten => s,1,Answer
exten => s,2,Background(CompanyA-intro)
include => CompanyA-extens

[CompanyB]
exten => s,1,Answer
exten => s,2,Background(CompanyB-intro)
include => CompanyB-extens

[CompanyC]
exten => s,1,Answer
exten => s,2,Background(CompanyC-intro)
include => CompanyC-extens
