[SIPForum-discussion] sip uri format with the +sign

[Nikos Leontsinis]

Hello Manpreet,

What about the case where there is no (+) and the number is in the format
(country code) (national code) which is
the case for most if not all international voip what would the absence of
the + indicate?

AFAIK the nature of address is an old isup feature to faciliate routing by
 creating 2 routing tables inside the legacy switch. I fail to see its
relevance in the modern NGN switches.
