To simplify customer management, Acrobits’ iOS/Android Softphone apps offer one-touch provisioning with QR codes.

The Cloud Softphone also includes extremely scalable pricing options to meet every need. Pay only for those features you have provided and those users you have activated.

Prioritize the codecs

Link copied to clipboard

Often a low Internet bandwidth channel will negatively affect audio quality. This situation occurs more frequently when calling parties use low-compressed codecs. In order to avoid voice interference, we recommend that you purchase the G.729 codec and give it a higher priority than the others. To do this, follow the steps below:

  1. Go to Codecs For WiFi settings.

    Go to advanced settings

  2. Prioritize the codecs. We recommend assigning the highest priority to the G.729 codec since it assures good audio quality even with a low bandwidth Internet channel. If an end user is sure that the G.729 codec is used on the remote side, all the other codecs may be disabled. This assures you that the G.729 codec will be used, even if it has not been prioritized on the remote side.

    Prioritize the codecs

  3. Disable the Honor Remote Codecs option. When this option is disabled, the application refers to the codec list customized by the end user. Otherwise, the application refers to the codec list that has been adjusted by the administrator on the Cloud Softphone profile.

    Disable the Honor Remote Codecs option

  4. Repeat steps 1-3 for the Codecs For 3G settings.

    Configure the Codecs For 3G option

The default priority of codecs can be adjusted by the administrator on the Cloud Softphone page.

Adjust the network type

Since it is not possible to send a voice stream from a private IP address to another private IP address from two local networks directly, the PortaSIP server engages the RTP Proxy server. The RTP Proxy server provides a public IP address so the call and voice stream may pass farther outside the local network. However, in some rare cases related to old Acrobits versions, a call from a private network can come to the PortaSIP server with a public IP address specified in particular SIP headers. In this case, the PortaSIP server sends the call directly to the callee’s network without RTP proxying. As a result, the voice stream cannot be delivered to a private network, so even though the call is established, the voice is absent. To assure that the call comes through the RTP Proxy server and that the voice stream is delivered, specify Internal in the Discover Global IP list. To do this, complete the following steps.

  1. Go to the NAT Traversal settings.

    Select NAT Traversal

  2. Select the Internal option in the Discover Global IP list.

    Configure global IP

For newer versions of the Acrobits application this option is adjusted by default.


Adjust the push options

When an end user closes the Acrobits application, the Acrobits push notification server (SIPIS) sends the registration to the PortaSIP server that indicates the closed status. If an incoming call arrives, the notification server tracks down the application’s status and wakes it up even if the status is “closed.” In some old Acrobits versions, the SIPIS server might send to the PortaSIP server a public IP address that is indicated in its particular registration headers. In this case, the PortaSIP server treats this registration as not coming from a private network. As a result, the RTP Proxy server is not involved and voice stream is not delivered. This issue can be easily overcome by enabling the Simulated NAT option.

New versions of the Acrobits application have this option enabled by default.

Adjust the Wi-Fi router

Link copied to clipboard

A Wi-Fi router may negatively affect the voice stream due to the router’s specific configuration. For example, the voice stream may not reach the Acrobits application if the SIP ALG option is enabled on the router side. In this case, a Wi-Fi router rewrites the audio source header in the SDP part of the SIP package, and as a result, the RTP Proxy server cannot send the media packages to the application located behind the Wi-Fi router. If this issue appears, we recommend disabling the SIP ALG option.

The names of the SIP ALG option may differ slightly on the different Wi-Fi router web interfaces.
