Re: dspfarm can impact on call transferring issue?

Hi Charles,

DSP resources (DSPFarm) can come into play when transferring calls (example from g.711 to g.729) Have a look;

Transcoding Support Overview

Versions of Cisco Unified CME earlier than Cisco CME 3.2 supported G.729 compressed voice calls for two-party calls only. Cisco CME 3.2 and later versions support transcoding between G.711 and G.729 for the following features:

Ad hoc conferencing One or more remote conferencing parties uses G.729.

Call transfer and forward One leg of a Voice over IP (VoIP)-to-VoIP hairpin call uses G.711 and the other leg uses G.729. A hairpin call is an incoming call that is transferred or forwarded over the same interface from which it arrived.

From this doc;

Hope this helps! Happy Holidays!
