[cisco-voip] DSP and voice resources...

[Ryan West]

Luis,

I believe you need a 1:1 ratio on the DSP's for signaling.  Once they are up, you can use the DSP for other functions, such as transcoding.  Try configuring two of the T1's as CAS and then do 'sh voic dsp group all' and you should see the shared vs signaling resources.  If you try to configure the 3rd T1 as CAS or PRI, you should get an error.

Hello, Group:

    I have an old cisco 5300 with 4 T1 PRI , when I do a show ver this
is what it displays...

IOS (tm) 5300 Software (C5300-JS-M), Version 12.3(3), RELEASE SOFTWARE
(fc2)
System image file is "flash:c5300-js-mz.123-3.bin"

cisco AS5300 (R4K) processor (revision A.32) with 131072K/16384K bytes
of memory.

96 Serial network interface(s)
4 Channelized T1/PRI port(s)
48 DSP(s), 48 Voice resource(s)


Now that this means I can only run 48 voice channels even though I have
4T1????... Or can I configure the router to pool the resources as need
it?.
