Important Notes Regarding IP Network Interface
Series 2 Cards

Do Not Mix Profiles

You cannot mix VoIP resource profiles on the same
IP Network Interface Series 2 card or in the same chassis.

255 Active Channels

For VoIP Resource Profile 2 on IP Network Interface Series 2, one channel on each VoIP module is reserved for ICMP Support. The full 256 channels per module can still be provisioned. The restriction is that only 255 channels can be active at one time. Attempting to use the 256th channel results in a negative acknowledgement of 0x28 (DSP Resources Not Available) to the Outseize Control (0x002C) or Route Control (0x00E8) API message. VoIP Resource Profile 1 does not have this limitation as it has an extra channel for ICMP support.

510 Simultaneous Calls

Even though 512 channels (16 spans, 32 channels per span) can be configured on a single IP Network Interface Series 2 card, only 510 simultaneous calls are allowed when using the default VoIP module resource Profile 2.
