Delayed Media

Overview

The CSP supports delayed media to allow interworking with third party call control applications (3PCC).

Description

• Delayed media is implemented for inbound calls. That is, the CSP can accept a delayed media call but does not generate one.

• The CSP accepts INVITE messages with SDP or without SDP or with held SDP.

• The CSP accepts SDP in the positive ACK message.

• Delayed media is not supported for bearer-free calls. It is supported for bearer calls only.

• Co nnect instructing coupling and connection mode is not supported. In delayed media, the destination IP address is not known at the time of coupling, therefore the CSP cannot outseize a n IPN-2 channel without the destination IP address and at the same time set the connection mode. The call will purge with reason 0x1A in this scenario.
