after reading alot of docs about DSP and transcoding and MTP, im confused. lets talk about most real scenario. i have 2 call manager 7835 and media service activated. i have also 2 2821 router with E1 Card each. users around 600 cisco ip phones and 120 3rd party sip phones. do we need DSP resources to call over ISDN.?? we are signle site no transcoding or .. h323 endpoint. does the Cisco 2821 embeded built with one DSP ??? i mean no need to buy another PVDM? i know 2821 can have up 2 3PVDM.
and incase i want to configure a transcoder and enhaced conferencing on the router , will enable SCCP , but also i want to use it AS MGCP gateway with E1 connected to PSTN? so can both SCCP and MGCP be active at the same time? SCCP for enhaced conf and transcoding and MGCP to control ISDN and FXO?
ok can i run both SCCP and MGCP on the same router. SCCP for transcode and conf and MGCP for media gateway control? well i have 2 PVDM2_64 and 2 PVDM2_32. ok as u said for each i need what excatly? configure the DSP as xcode or as MTP or as what? i have around 600 ip phones mix sccp and sip. your advice and if u can provide me with sample configuration
also the IOS enhanced conferencing guide contains a lot of explanation of the usage and capabilities.
As Paolo mentioned the calculation is not as simple as asking how and what, you need to know the HW, where the cards are located, where the DSPs are, how many interfaces will be working, which codecs they will handle, etc
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
