Conference Calling on a Cisco 9971

[jeanvaljean]

We are having a problem with the Conference Feature on our 9971's.

We make the first call, then press the Conference Button and dial tone is returned; at that point you have to dial the digits of the next call extremely fast or it 'times out' and your call fails.

On a Nortel system I would probably think this was a matter of setting the EOD timer on the Route Data Block, but I'm not sure where to look on the CUCM, (Rls 8).

Any input would be appreciated!

the timer is under system parameters and it is the T302 timer(interdigit timeout) if I recall. By default it is set to 15 seconds.
Since the 99XX series phones are SIP phones you might want to look under the SIP params in system params as well and make sure that there is not a specific interdigit timeout parameter for SIP devices.

Thanks for the quick response!!

It appears that the SIP profile is at default values: the "off hook to first digit timer" is set to 15000 milliseconds(15 seconds).

From the time you press the conference button on the 9971 there is only approx 1-2 second window (max) to dial the second call.

On the SIP profile we changed the Timer T1 (default at 500 millliseconds) to be 1000 milliseconds (1 sesond) but it made no difference.

Still looking ...

perhaps you need to adjust your sip session timeout timer then.

this is for my template

1. Set up and associate the physical phone.
The easiest way to avoid searching through lines of configuration or hunting an automatically registered phone is to set up the phone association before plugging it in to a switchport on the network. In other words, give the router a "heads up" that the phone is about to be initialized.
THHQRV1-3845# configure terminal
THHQRV1-3845(config)# ephone 1 #Configuration mode for ephone
THHQRV1-3845(config-ephone)# mac-address 11aa.22bb.33cc #The MAC address for the phone
THHQRV1-3845(config-ephone)# button 1:5 #Assign buttons to the phone by using the ephone-dn
THHQRV1-3845(config-ephone)# type 7962 #Set the phone type
THHQRV1-3845# show ephone ? #Show a list of supported phone types.

2. Create Voice user profile for Extension Mobility
voice logout-profile To enter voice logout-profile configuration mode to create a logout profile and define the default appearance for a Cisco Unified IP phone enabled for Extension Mobility, use the voice logout-profile command in global configuration mode. To delete an logout profile, use the no form of this command:
THHQRV1-3845# configure terminal
THHQRV1-3845(config)# voice logout-profile 1 #Create logout profile
THHQRV1-3845(config-logout-profile)# pin 123456 #Set a PIN to be used by a phone user
THHQRV1-3845(config-logout-profile)# user logout password logout

To configure a user profile for a phone user who logs into a Cisco IP phone that is enabled for Extension Mobility, perform the following steps:
THHQRV1-3845# configure terminal
THHQRV1-3845(config)# voice user-profile 1
THHQRV1-3845(config-user-profile)# user 7222 password 45678
THHQRV1-3845(config-user-profile)# number 7222 type normal
THHQRV1-3845(config-user-profile)# speed-dial 1 90892046844 label "On Call"

3. Creating Directory Numbers
Create an ephone-dn by using the following commands after logging into and enabling your router:
THHQRV1-3845# configure terminal
THHQRV1-3845(config)# ephone-dn 1 dual-line
THHQRV1-3845(config-ephone-dn)# number 7222
THHQRV1-3845(config-ephone-dn)# pickup-group 10
THHQRV1-3845(config-ephone-dn)# description Sumuscha T
THHQRV1-3845(config-ephone-dn)# name Sumuscha Teesr
THHQRV1-3845(config-ephone-dn)# call-forward busy 7111
THHQRV1-3845(config-ephone-dn)# call-forward noan 90811711942 timeout 18

4. Check your running configuration.
You can check your running configuration (ephone-dn, ephone - and other things)
THHQRV1-3845#show running-config
