IP Phone to unknown number

[chingkiatlee]

Dear all,

Is any tested to using the Cisco IP phone calling to any unknown internal DN (2xxx to CTI Route point for IPMA), after on-hook the headset.

The IP phone will hang for almost 10 sec timeout, then only disappear the display.

thank you

I have test with Cisco 7945, the delay around 10 sec.

For Cisco 8941, it seems like drop faster..

is it the phone software issue?

Hi Lee,

I could not find much on delay issue but how come u are using 8941 for IPMA since I was referring the link which does not show IPMA supported for 8941 phone.

Hi,

I mean my customer environment do have using the IPMA features, so i do have an CTI with 2XXX as a DN number.

My issue now is if i do make a call to any directory which is not registered or not listed in the DN list, by right it should be call into the CTI route point.

But after i end of the call (on-hook the headset), it should be terminated the session upon i disconnect it.

For Cisco 8941, it can be stop it immediately.
For Cisco 7945, it will hang it and disappear after 10 sec timeout.

thank you.
