Configuration

Firmware version

All innovaphone devices use V10 SR12 as firmware.

SIP - Trunk

Image:GlobalConnect_SIP-Trunk_-_SIP_Provider_Compatibility_Test_1.png

A SIP interface can be used to connect to the provider. Make sure to configure the SIP Interop Tweaks as in the screenshot above. MediaRelay is not needed.

Number Mapping

Image:GlobalConnect_SIP-Trunk_-_SIP_Provider_Compatibility_Test_2.png

The provider will send and receive all numbers (CGPN & CDPN) in international number format.

Route Settings

Image:GlobalConnect_SIP-Trunk_-_SIP_Provider_Compatibility_Test_3.png

The provider does not support overlap dialling, so Force Enblock must be activated in the route from RS1 to SIP1.

Since Clip No Screening is supported, make sure to have a route mapping that adjust calls with numbers other than the own trunknumber to a proper format. (see screenshot comment Clip No Screening)

Known Problems

  • In order for CLIP No Screening to work, we must configure the use of the P-Asserted Identity as shown below.
