Configuration

innovaphone configuration

For calls to the Siemens configure a Gateway Interface without registration, as Proxy put the Ip address of the Siemens HG3500 module.

If you deal with different codecs (different innovaphone phones with different preferred codec settings and/or different MOH or WQ codec files), it is recommended that you set your codec settings on the Gateway interface to the Siemens HIPath to exclusive. Also use Media relay as the Siemens can get in troubles having invites from different Ip addresses.

In the routes enable the Interworking flag in both ways.

The innovaphone can send digits with overlap to the Siemens HIPath, so no en-block enabling is necessary.

3rd party product configuration

Here it shows how to configure the Siemens HIPath in detail (in German language)

HIPath configuration

Known Problems

• On Siemens side en-block dialing must be enabled, as the Siemens can only send numbers via Sip in en-block dial.

• CCBS/CCNR is not possible.

• Calls from Siemens to innovaphone, the connected Name will not be shown up on the Siemens Endpoint.

• Connected Name does not show up on Siemens phones when calling from Siemens to innovaphone
