Hi All, Yes, it is not usual to receive a PAI with Anonymous URI. The PAI would typically not be included instead.
However, a From header can contain an "anonymous" or "unavailable" user identity. Pl. refer to 3GPP TS 23.003 (Section 13.6 in v8.17.0) as well as 3GPP TS 29.163 (Table 3/Table 12 in v8.20.0).

Hence nobody is in a position to make such an assertion. But it could be appropriate to assert sip:anonymous@somedomain. This would presumably mean: this is from *some* valid user of somedomain, but which one is being withheld. This has more utility in domains with many users than in those with just a few. This has even been discussed in the ongoing work in the ietf STIR wg. Thanks, Paul On 7/2/14 12:30 PM, Joel Gerber wrote: > It's valid, but more than slightly silly.
