Howto:GlobalConnect SIP-Trunk - SIP Provider Compatibility Test

Innovaphone Compatibility Test Report

Summary

GlobalConnect

The provider does not support all required innovaphone features and is therefore not qualified as recommended SIP Provider.

The main reason for not passing the test is the missing ring tone when external calls(PSTN) are forwarded back to the PSTN. Additionally the provider doesn't support CLIR, ClipNoScreening and Redundancy scenarios with multiple SIP-trunks(master & standby) registered at one account.

Configuration

Firmware version

All innovaphone devices use V10 SR12 as firmware.

SIP - Trunk

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

Number Mapping

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

Route Settings

The provider doe 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.
