[cisco-voip] Bandwidth Requirements between CUCM Cluster and distributed Unity Connection

[Keith Allan]

Mathew,

 

Thank you for your comments.  The reason for Unity Connection being
located on a remote site is because the gateway is also located on the
same site and the bandwidth between the sites is limited.  I did see a
comment once stating we should treat each voicemail port as a phone and
allow the appropriate QOS across the WAN.

 

Thanks again.

 

Keith.

Keith -

 

I don't think there are any specific requirements, primarily because of
how unity works.  Essentially, Unity is represented to CallManager by
the voicemail ports, which are just SCCP devices (or a SIP trunk,
depending).  The bigger concern (depending on your topology) is not the
distance from CallManager to Unity, but the distance from the ingress
voice gateways or originating IP phone to unity as that's where the
voice stream is.

Hi,  We have a centralised CUCM cluster and need to install Unity
Connection on a remote site. The design guides show this is supported
but I can't find any minimum bandwidth requirements for the WAN between
CUCM and UCN other than the standard min 150ms one way delay.

 

Does anyone know what these requirements are before we go ahead and
deploy?

 

many thanks,  Keith.
