Webdial from Excel

Here it is an Excel formula to call a number using Cisco Webdialer:

A1                   A2
0012345          =HYPERLINK(https://server:port/webdialer/Webdialer?destination="&A1,"Dial")

Cisco ATA 187 and fax

ATA 187 does not work well with some fax devices, in our case it is Xerox 7228. The config that works (little bit weird): enable t38 on outgoing and disable on incoming

dial-peer voice 300 voip
no modem passthrough
session target ipv4:192.168.25.1

update: moved from ATA to FXS card in router and all issues are gone - isn't it a magic? Heh, Cisco?  :)

Cisco IP phone BLF button does not pickup call

Please refer to the Cisco prerequisites for call pickup: http://www.cisco.com/en/US/docs/voice_ip_comm/cucmbe/rel_notes/6_1_2/cucmbe-rel_note-612_2.html#wp308333 I my case there was an issue with the following: "The call pickup group for the monitoring user must contain the pickup group for the monitored destination, or call pickup will fail" Now when the reception and the user extension are in the same or in the inherited groups and it works ok.
