Hi, Sanjiv,
As per RFC3325, scheme other than sip, sips and tel can only be used when
there are more than one P-xxx-ID values.
9.1 The P-Asserted-Identity Header
The P-Asserted-Identity header field is used among trusted SIP
entities (typically intermediaries) to carry the identity of the user
sending a SIP message as it was verified by authentication.
PAssertedID = "P-Asserted-Identity" HCOLON PAssertedID-value
*(COMMA PAssertedID-value)
PAssertedID-value = name-addr / addr-spec
A P-Asserted-Identity header field value MUST consist of exactly one
name-addr or addr-spec. There may be one or two P-Asserted-Identity
values. If there is one value, it MUST be a sip, sips, or tel URI.
If there are two values, one value MUST be a sip or sips URI and the
other MUST be a tel URI.
