Configure IOS Hardware transcoding resources in order to meet following Requirements.
1) Site B IP phones should be able to call ICD Route point number 2400 using G729 codec.
2) HQ and Site B IP phones should be able to call Cisco Unity Express
voicemail pilot using G729 codec.
On HQ Router
Check SCCP configuration.

Register transcoder resources in SCCP CCM group.
R1(config)#sccp ccm group 1
R1(config-sccp-ccm)#associate profile 1 register hq-xcoder
Now we need to Check configuration.

We have to configure 3 transcoding sessions here. The reason for this we have 3 CTI ports for the CUE (and they use G711ulaw) and they ask for CUE ports specifically.
Register transcoder resources in SCCP CCM group.
R1(config)#sccp ccm group 1
R1(config-sccp-ccm)#associate profile 1 register sc-xcoder
On CUCM side
Register the transcoders for HQ and Site C (Cisco Unified CM Administration→Media Re-sources→Transcoder).
HQ Transcoder
Site C Transcoder
Add the transcoders to HQ and Site C media resource groups (Cisco Unified CM Administration→Media Resources→ Media Resource Group).
Site C Media Resource Group
Call to 2400 from Site B IP Phone and check on R1 if transcoder is used.
