The Tool for Auto-Registered Phone Support (TAPS) loads a preconfigured phone setting on a phone. The TAPS works in conjunction with the Bulk Administration Tool (BAT) to minimize installer effort during phone placement. After the BAT is used to bulk add phones with dummy MAC addresses to Cisco Unified Communications Manager, you can plug the phones into the network.
The administrator or the phones’ user can then dial a TAPS directory number, enter their extension and that causes the phone to download its´ configuration. At the same time, the phone gets updated in the Unified CM database with the correct MAC address of the phone.
Cisco Unified Communications Manager started to support a leading “+” as part of routeable patterns and as such also directory numbers with release 7.0. Customers intending to use TAPS (Tool for Auto-Registered Phones) to provision phones with a “+” in the directory number hit a problem in that phones can not send “+” as DTMF which would be required as part of the TAPS call flow to instruct the TAPS application which phone configuration to apply to the calling phones.
This application note will describe how to modify the TAPS application to resolve that issue and deploy phones with +E.164 directory numbers using TAPS.
