Call Types and Licensing
Room and Desktop Registrations on Expressway
Expressway-C can now be used as a SIP registrar for telepresence room and desktop systems. We have also
introduced a new licensing model for calls that go through the Expressway, to align more closely with the Unified CM
licensing model.
introduced a new licensing model for calls that go through the Expressway, to align more closely with the Unified CM
licensing model.
When you configure the Expressway as a registrar, you must license it for concurrent systems (CUCM model), rather
than for concurrent calls (VCS model). You can do that by adding either or both of the following license types to the

than for concurrent calls (VCS model). You can do that by adding either or both of the following license types to the
Expressway-C:
■
TelePresence Room System License
■
Desktop System License
The following devices register as desktop systems with all other devices considered room systems:
■
Cisco TelePresence EX60
■
Cisco TelePresence EX90
■
Cisco DX70
■
Cisco DX80
Scope of the registrar feature:
■
Option keys containing licenses for local registrations are installed on the Expressway-C.
These licenses are pooled in a cluster, that is, Expressway-C peers can use each others' licenses. However,
rooms cannot use desktop licenses, nor can desktop systems use room licenses.
rooms cannot use desktop licenses, nor can desktop systems use room licenses.
■
Registrations from outside the network are proxied to the Expressway-C by the Expressway-E. The
Expressway-E cannot accept direct registrations.
Expressway-E cannot accept direct registrations.
■
Device provisioning and FindMe are supported with Cisco TelePresence Management Suite.
■
H.323 registrations are not currently supported.
■
The Medium VM (or CE1100 with 1 GBps NIC) can support up to 2500 registrations. The Large VM (or CE1100
with 10 GBps NIC) can support up to 5000 registrations.

Local registrations, proxy registrations (via Expressway-E), and MRA registrations (proxied to CUCM), all count
towards this number.

Implications of the new licensing model:
■
Rich Media Session license usage has been reduced, following the principle that if you have already paid for a
registration license you should not also pay for the Rich Media Session.

■
Calls between registered systems do not use RMS licenses. Here, "registered systems" means systems
registered directly to the Expressway-C, by proxy to the Expressway-C through the Expressway-E, or by proxy
through the Expressway pair (MRA) to neighbored Unified CMs.

Calls from registered systems (as above) to Cisco infrastructure do not use RMS licenses. Currently, this
extends only to Acano server, or to TelePresence Server when managed by TelePresence Conductor.
