Incoming internal calls to the customer helpdesk current are sent via CallManager Trunk with MTP enabled.
(See: Forum Response "Contact Center: CVP using DSP Resouce for G.711 calls").
The MTP resource used is a 2821 with 72 DSP's dedicated for MTP for the CCM Trunk only. No more than 30% is ever used. When I make several calls to the Helpdesk (CCM Trunk > GK > CVP > VXML GW). I get silence on approx every 20th call. Is there any debug or show command that would show me that I'm reaching a threshhold on either the vxml gw or the dsp router? My vxml gateway is a AS5350XM which I understand can cope with 20 simultaneous calls.
Many thanks, Michael
