[OpenSER-Users] [OT] Nortel gateway allows "tel:1234 at host" but not "tel:1234" ¿?¿?¿

[Iñaki Baz Castillo]

Hi, I'm trying "P-Asserted-Identity" header against a Nortel CS2000_NGSS/8.0.
It works (the number in PAI header is shown as PSTN callerid number) in those 
cases:

  P-Asserted-Identity: <sip:+34666555444 at host/IP>
  P-Asserted-Identity: <tel:+34666555444 at host/IP>

As you can see, the second case is wrong since a "tel" uri has no host part 
according to RFC 3966 [1].

And the worst thing is that Nortel disallows or doesn't understand a correctly 
formed "tel" uri in PAI header as this:

    P-Asserted-Identity: <tel:+34666555444>


My experience with gateways is very limited and new, but I should assume that 
it is a sad bug in the Nortel SIP stack, is it?

Thanks for any help.
