How to check for available DSP's

IP Line and Trunk cards can be redeployed as Digital
Signal Processor (DSP) resource cards if you started with these and then introduce a Signalling Server
I am thinking you would need to do a card inventory of your system(s) in LD 117 (inv gen cards) and then print it (inv prt cards). Then look for IP line or trunk cards

DSPs are digital signal processors. They are found on media gateway cards. The DSPs provides transcoding between IP and TDM phones.
SS is the signalling server. It's the IP interface for IP phones just like we have analog cards for analog phones.
Go to Element Manager >System Status>IP Telephony Information
Select one of the media cards and issue the command:
DSPNumShow
Media Cards are of three types - 8 DSPs, 24 DSPs and 32 DSPs

Your dsp's are also referred to as "Channels" on your Media card. These are the bottleneck of IP telephones to copper calls whether they be an analog set, a digital set, or a call to the outside world. If you can get to your pbx and look at the cards, find the loop, shelf, and card number.
Do a stat on it and it'll show you how many you have active or disabled, that are idle or busy. You can also see them in the element manager. They do the compression/decompression and determine the codecs you're using. Your IP sets never hit the media cards if they're goin' IP to IP. Only when an IP phone makes a call that's not IP. They have to convert (for lack of a better term) the IP call back so it can go out to something other than another IP set.
I only know this because I got REAL intimate with ours when the folks that setup our VoIP left the old 24 channel ITG card in the pbx and not configured on the node OR terminated to ethernet. They left 2 of the channels on it active and we kept dropping calls when they were incoming. The PBX would use one of those channels that went NOWHERE and terminate the call. The only way I found it was to go to a TDM set and call my IP set over and over and over again until I had no speech path but the call/line was staying open. Then I went and did a trac on that tn and found it...
