[nsp] as53xx SIP and DSP

[ewc at axelero.hu]

Hello,

is there a need to have DSPs (VFC cards) for making this:

PSTN ---> Cisco 53xx ---> G.711 SIP or H.323 --> another gw
PSTN <--- Cisco 53xx <--- G.711 SIP or H.323 <-------+

On Cisco 53xx (or 5400) should be no IVR configured, just incoming and
outcoming dial-peers.

I read on cisco.com, that TDM switching works woithout DSPs, but it
was not clear if the asked configuration will work also.

Thanks in advance,
        Thomas
