And they have the nerve to call their IM extension "SIMPLE".
It also shocks me how prevalent SIP is for arbitrary lookups in telcoland. More than one switch uses a SIP call to find number portability info. So they involve at least 3 SIP messages, each hundreds of bytes long, complete with a full SIP transaction state, burning up call resources on their switch, to essentially send and receive 10 bytes.
The amount of stupidity in telecom is mind-boggling. I take solace in hearing that other industries are just as bad, but I don't see them so they just appear to be OK.
