Manpreet,
If you read it in that way I can accept it. However, there is no
sentence in the rfc 3261 rendering this rule as mandatory. It can only
be perceived as a product of convention between international carriers.

With no +, there is not always a good indication where the format has
country code. The whole intention was to make interworking between ISUP
and SIP clear from NOA perspective. Unless discussed on the
international interconnection, + or no + confirms if the numbers
contains country code or not. All international interconnections require
a + beyond the national domain otherwise they are treated as National.
Thanks

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.

This would be to put the Nature of address logic in the B number. +
would be international NOA and without + could be national or unknown
and routing could be done differently.
Thnx

I see that there are many carriers having adopted the sip uri with the +
in front
example:
sip:+1-212-555-1212:1234 at gateway.com
<mailto:sip%3A%2B1-212-555-1212%3A1234 at gateway.com> ;user=phone
This is not mandatory looking at the rfc 3261 is there any motivation
behind this decision?
