• The ISR 4000 software MTP restrictions include no hardware MTP for repacketization, no per-call debugging, no call threshold for standalone software MTP, and no RSVP agent. in context
• The ISR 4000 software MTP bridges media between two connections so Unified CM can relay calls routed through SIP or H.323 endpoints. It registers with Unified CM over SCCP, and its capacity is set with the maximum sessions software command. in context
• For the ISR 4000 software MTP to work, the codec and packetization must be configured identically on the inbound and outbound call legs. in context
• If an MTP is needed only for DTMF, Early Offer or IPv4/IPv6 conversion and both legs use the same codec and packetization, a software MTP (Unified CM IPVMS or ISR software MTP) is likely sufficient. If codecs differ, a DSP transcoder is likely needed. inferred in context
