Procedures for Using Mid-call Services
The method of initiating and using mid-call services during a call when using SCCP differs according
to mode, which is configured by the Cisco ATA administrator using the ConnectMode parameter (see the
“ConnectMode” section on page 5-13). Use the procedures for the mid-services mode that is configured
on your Cisco ATA.
The following three modes are used for invoking mid-call services:
• Bellcore Style, page A-4
• Cisco VG248 Style, page A-5
• Cisco ATA Style, page A-6
Bellcore Style
The following two procedures are unique to the Bellcore (default) style:
• Bellcore Style Call Transfer Procedure, page A-4
• Bellcore Style Conference Call Procedure, page A-4
Bellcore Style Call Transfer Procedure
Step 1 Perform a hookflash to place the current call on hold and obtain a second dial tone.
Step 2 At the dial tone, enter the telephone number or speed dial of the third party and wait for the call to ring.
Step 3 You have the following options:
• To transfer the call, hang up when the call rings or when the third party answers.
• To return to the original call, perform a hookflash before the call rings. If you perform a hookflash
before the third party answers but after the call rings, you also return to the original call.

before the third party answers but after the call rings, you also return to the original call.
