Enabling Trasncoding on CME

[Leo Salcie Tejeda]

Hi,

I tried to enable a Transcoding DSPFarm for CME itself, I have tried this same setup for Conference DSPFarm and it worked but I don't why got the  error: Cause Code: TCP_CONN_ERROR. I have tried to follow some advice seeting up a Loopback but still didn't worked.

I have realized with another CME with a working transcoding DSPfarm that I should to be able to make a telnet to port 2000 and be able to see the sccp process running listening at the same port too but I was unable to do it.

Below the CME setup:

voice-card 0

dspfarm

dsp services dspfarm

sccp local Loopback0

sccp ccm 192.168.100.1 identifier 1 priority 1 version 4.0

Hi,

Your profile association seem to be wrong

sccp ccm group 1

associate ccm 1 priority 1

associate profile 1 register CME_TRANSC

|

telephony-service

sdspfarm units 5

sdspfarm transcode sessions 2

sdspfarm tag 1 CME-TRANSC

Either change your profile to

associate profile 1 register CME-TRANSC

or your sdspfarm tag to

sdspfarm tag 1 CME_TRANSC

Both your profile and sdspfarm tag should match

No worries , i just wanted if it fixed or not.

Just checked my mail and found its fixed ... I am posting the answer again for reference.

You need to set max-ephone and max-dn to bring the telephony service up. Those are mandatory configurations. You was missing them from your config.

Mohammed,

Yes I can confirm that the adding max-ephone 5 and max-dn 5 enabled the trabnscoder to register. Like I said I accidentally deleted Leos response to the post which confirmed it was the correct answer. Hopefully he will re-rate the post again.
