IANA has questions about draft-ietf-sieve-managesieve-05.txt:
- This document requests the allocation of a TCP port that has
already been registered (2000, Cisco SCCP). Should the existing
registration be changed from "Cisco SCCP" to "ManageSieve"?
Dan,
ManageSieve was invented about 10 years ago and some implementations
used port 2000 (unfortunately without registering it with IANA). How
widely is Cisco SCCP implemented and would be changing the IANA
allocated port number an option for you?
SCCP is our proprietary signaling protocol between our VoIP phones
and Unified Communication Manager (formerly called Call Manager),
with somewhere above 6 million IP phones in the field (as of
2005,
<http://newsroom.cisco.com/dlls/global/asiapac/news/2005/pr_09-23.html>,
most of which use SCCP.

To the WG: how widespread is usage of port 2000 for ManageSieve? Are
people using any other port numbers?
