Configuring Confence Now

Key Aspects of Conference Now

A maximum of 100 simultaneous Conference Now and Meet-Me conference are supported per CUCM node
The maximum number of conference parties is controlled by the existing CallManager service parameter Maximum Meet-Me Conference Unicast
Once you are placed into the conference, you are no connected to the IVR CUCM - but connected to configured CUCM Conference Resource
The Conference Resource selected by CUCM (confirmed from testing) is determined by device MRGL of the Conference Host , i.e. the Conference Host device (e.g. their phone's MRGL or if opening externally via the specific gateway's MRGL)
Once the Host opens the bridge the bridge stays open until all callers leave the bridge (even if host leaves the bridge)
DTMF Digits - The IVR supports only Out-Of-Band (OOB) DTMF digit collection method. If there is a DTMF capability mismatch between the calling device and the IVR, an MTP will be allocated.
Codecs - The IVR only supports codec G.711 (a-law and mu-law), G.729, and Wide Band 256k. If there is a codec mismatch between the alling device and the IVR, a transcoder will be allocated

MTP resources

For SIP Calls coming in a gateways - you must include sip-kpml as a SIP DTMF relay option, otherwise an MTP resource will be required for the duration of that call.

The Below voice dial-peer dtmf-relay configuration will both RFC 2833 (rtp-nte) and 'Out-of-band (OOB)' sip-kpml.

dtmf-relay rtp-nte sip-kpml

Note: there is no difference in the SIP Invite and SDP if you change the order of above. i.e. there is no technical way to inform the other SIP endpoint you have a preference for KMPL over RFC2833 (NTE). But Cisco phones do 'prefer' NTE mode - when both are offered (but they support both).

Audio Prompts

Annoucment Identifier	Annoucement Text	Notes
ConferenceNowGreeting	Welcome. To Join a Conference Now, please enter a meeting number, following by hash.	Include a call recording warning if call is recorded, e.g. 'Welcome to Purplepi Conferencing. Your Call May be recorded for training and quality purposes. Please enter a meeting number, following by hash.'
ConferenceNowNumberInvalid	The meeting number that you entered is invalid, please re-enter the meeting number
ConferenceNowEnterPIN	If you are the meeting host, please enter your PIN, otherwise press hash to continue.
ConferenceNowInvalidPIN	The PIN that you entered was invalid, please re-enter your PIN
ConferenceNowEnterAccessCode	Please enter the attendee access code, followed by hash.
ConferenceNowAccessCodeInvalid	The meeting access code that you entered is invalid, please re-enter the meeting access code
ConferenceNowNumberFailed	The meeting number that you entered is invalid, please ask the meeting host for the correct meeting number. Goodbye.	after 5 failed attempts
ConferenceNowAccessCodeFailed	The meeting access code that you entered is invalid, please ask the host for the correct access code. Goodbye	after 5 failed attempts
ConferenceNowFailedPIN	The PIN that you entered is invalid, please ask the system administrator for the correct meeting number and PIN. Goodbye.	after 5 failed attempts
ConferenceNowCFBFailed	<not sure of exact wording!>	Note this prompt for NOT play if the System Parameter “IVR” Call Count is reached. Call is just rejected! i.e. even though the documents state 'Plays when the conference bridge capacity limit is exceeded while initiating Conference Now' I assume it will be played if more than 100 concurrent conference are reached on a specific node.

Head Office Gateway

Caller has Calling into Conference Now

Note Use of an MTP.Why?

Once user joined the conference, if the bridge is not opened, the user hears MoH and the MTP is removed from the call.

DTMF Debug

using the show sip-ua calls* on the gateway you can confirm the Dtmf-relay Negotiated, e.g. in below example - it is kpml**. Note: the 'show sip-ua calls dtmf-relay sip-kpml' does not seem to work. As it shows '0' calls even if a call is using KPML as per below.
