DTMF SRTP interworking |
Currently, Unified Communications Manager inserts MTP for a DTMF mismatch in both secure and non-secure calls. But for secure calls, though MTP is inserted for a DTMF mismatch, it just passes through the media between the parties. Hence, the DTMF events are not sent between the parties. Before Unified CM Release 14SU3, DTMF translation worked only for non-secure calls when there was an MTP allocated for a DTMF mismatch. With this release, Unified CM can invoke a hardware MTP (with SRTP DTMF interwork support) for a DTMF mismatch between secure endpoints. |

iOS Local Push Connectivity for Calls |
Webex App is not notified of incoming VoIP call notifications when an iOS device operates in a Wi-Fi constrained network with no internet connection such as, hospitals, cruise ships, airplane, and so on. Due to lack of internet connectivity, the device does not have access to the Apple Push Notification Service (APNS). Users expect to receive calls without any delay. However, with APNS a call can be delayed for a few seconds when there is a network latency. With this release, Local Push Notification Service (LPNS) for calls has been introduced on Apple devices. It helps to minimize any delay as the push message is sent to the client through a persistent connection. |
