[cisco-voip] MTP won't register

[Kevin Thorngren]

You have the profile configured as a transcoder but it should be configured as MTP.  

Your config:
sccp ccm group 100
 bind interface GigabitEthernet0/0
 associate ccm 2 priority 1
 associate ccm 1 priority 2
 associate profile 6 register MTPf866f218dc20
 keepalive retries 5
 keepalive timeout 10
 switchback method immediate
 switchback interval 30
!
dspfarm profile 6 transcode
 codec g711ulaw
 codec g711alaw
 codec g729ar8
 codec g729abr8
 maximum sessions 8
 associate application SCCP

For example:
sccp ccm group 999
 associate profile 12 register MTP123456789

dspfarm profile 12 mtp
 codec g711ulaw
 maximum sessions hardware 4
 maximum sessions software 40
 associate application SCCP

See this doc for more details about MTP support and config:
