ICM CTI campaing Outbound option

Below snippet  from ICM 7.5 SRND that tells you what codec the dialer supports on its different legs, you can configure the device pool on the your VIP 30 phones accordingly.

The Unified Outbound Option Dialer should be co-located with the Unified CCE PG and the Unified CM

cluster (including the voice gateway). Because the Dialer supports only G.711 mu-law, you might have

to allocate large blocks of WAN bandwidth. Even though the Dialer does not support G.729, it is possible

to support G.729 for the customer-to-agent portion of the call. This type of configuration is supported

without requiring the use of transcoders.

In this deployment, the Dialer advertises G.729 capability (although the Dialer does not truly support

G.729). This permits the reservation call from the Dialer to the agent to be completed. The call from the

Dialer to the customer must be G.711; however, the customer call is then transferred to the agent and the

call is renegotiated to G.729.

Hope this helps
