Description

 

 

 

 

 

 

 

 

CSCdr36331

 

Going from low bit rate to low bit rate, the wrong counter is sent from a transcoder.

 

 

 

The problem occurs when the system is configured, so a transcoder is invoked to

 

 

 

transcode between two low-bit-rate codecs (for example, from a G.723 to a G.729).

 

 

 

 

 

 

 

 

 

 

 

 

Note

 

Cisco CallManager Release 3.0 does not support the use of a

 

 

 

 

 

 

transcoder to support low-bit-rate to low-bit-rate transcoding.

 

 

 

 

 

 

 

 

 

When a transcoder is invoked to transcode between two low-bit-rate codecs, the

 

 

 

transcoder consumes the internal resources of two transcoders, but only one

 

 

 

transcoder is allocated.

 

 

 

As a result, more transcoders are available to be allocated in the system than there are

 

 

 

internal transcoding resources to support them. When all available internal

 

 

 

transcoding resources are in use, and another transcoder is allocated and begins

 

 

 

transcoding, the voice quality on all calls going through that transcoder device

 

 

 

degrades noticeably and, sometimes, severely.

 

 

 

Workaround: Cisco highly recommends that the system be carefully configured, so

 

 

 

that transcoding between low-bit-rate codecs is not required.

 

 

 

No workaround exists for this problem other than limiting the number of calls

 

 

 

through a given transcoder device by expanding the number of transcoders available.

 

 

 

Having at least twice as many transcoders available as there are calls that need them

 

 

 

at any given time should eliminate this problem.

A <CmdArg>[Object Error]<noCmdArg> error message returns when a user is added

 

 

 

via the Cisco CallManager administration page.

 

 

 

If users have been added to the system via private scripts, the directory may not allow

 

 

 

some userid name conflicts to occur but does not properly report the conflict. For

 

 

 

example, a user with the userid of "jsmith@company.com" will conflict with the

 

 

 

proposed userid of "jsmith.” This problem should not appear through normal usage

 

 

 

of the product.

 

 

 

 

 

 

Workaround: Use a different userid for the new user or access the directory directly

 

 

 

to delete the conflicting user.
