h this dsp image.

Jan 26 21:54:16.323: %DSPRM-5-UPDOWN: DSP 7 in slot 1, changed state to up

I have this error on Cisco3745 which is configured as voice gateway.

Network:

Cisco 3745 is connected to PBX e1 cards using 2 Controller E1(NMHDV) QSIG.

Some of the calls made by agents are getting disconnected. This is a call center. I have huge no. of calls @ 25 calls dialed out in 10 seconds.

PBX vendor says disconnect message coming from Cisco which is connected by e1 pri.

About this error Cisco website says

""The %DSPRM-5-SETCODEC error is caused by having a high complexity codec configured on a VoIP dial-peer while still having the voice card set for the default of medium complexity""

http://www.cisco.com/en/US/tech/tk652/tk701/technologies_tech_note09186a00800b6710.shtml

But my Voice Class codec is this

voice class codec 100

codec preference 1 g729r8 bytes 40 - medium complexity only

codec preference 2 g723r63 bytes 48

codec preference 3 g723ar63 bytes 48

WHAT ELSE CAN BE THE PROBLEM.

How to FIX this guys….

Thx very much.

Hi

See this document:

http://www.cisco.com/en/US/tech/tk652/tk701/technologies_tech_note09186a00800b6710.shtml#code_com

According to this G723 is a high-complexity codec, so you'll need to have the 'codec complexity high' command under your voice-card...

You need to clear out the config of your E1 before changing the complexity.

The error stopped coming.

Instead i removed the high complexity codec prefereneces from the voice codec class.

Thanks Aaron
