If the number of DSP resources required is as the following
DSP required for 5 Conference bridges = 5
and DSP required for 32 Transcoder sessions = 8 (each DSP can accommodate 4 transcoder sessions)
How many DSPs required for ( maximum sessions hardware 10 and maximum sessions software 10 ) ?

Have you already checked out the DSP calculator? It's a bit more complicated than what you've noted, because you don't account for number of codecs to be used, complexity of codec, number of conference participants allowed, etc.

I couldn't use the tool .
I just need to know
How many DSPs required for ( maximum sessions hardware 10 and maximum sessions software 10 ) ? using G711ulaw

The tool requires this info in order to give an accurate calculation
Router model
OS version
Interface cards installed
How many concurrent xcode sessions to support
How mnay concurrent conference sessions to support
Number of participants in conference
I ran it with the following, as an example, and it spit out that a single PVDM3-64 was needed
Router: 2921
OS: 15.1(4)M
1x VWIC2-1MFT-T1/E1 (T1)
1 Low complexity voice codec for T1
10 low complexity transcode sessions
10 low complexity 8-party conference sessions

thanks for your reply but

without using the tool

It's there for a reason (this is a complicated question without simple answer, based on your actual router build). I can't give you an answer based on incomplete requirements. Someone else may, but note that mileage will vary based on what else you have in that router that'd use DSP's.

If you want to do the math by yourself read this link

As it has been stated before, without full details of codecs and other data you can only get a rough estimate, either you use the DSP calc or you do the math using the info from the above link.
