At the Monterey meeting we discussed the possibility of an addition to the Implementer's Guide to support caller ID features (APC-1527). H.225.0 V2 (and V1) forbids the use of octet 3a in the Calling Party Number IE (and also specifies that the octet 3 extension bit shall be set to 1). The proposal calls for removing the restriction through the Implementer's Guide. (See also the meeting report in APC-1554b.)

Fixing this brings up the possibility of interoperability problems with existing products. Please respond if you think this change will be a problem. You can respond to me individually, rather than to the entire list, if you prefer.

Thanks, Glen
