Configuration
Firmware version
- version 9.00 hotfix4
SIP - Trunk
First of all the SIP Trunk must be configured. Since Colt authenticates a user account only by IP - Address, you cannot use the normal SIP-Gateway object. You need to configure a GW without registration and route the calls to the PBX. Make sure that Media Relay is activated and an exclusive codec is selected.
Number Mapping
Route Settings
Because Colt, as most SIP - Providers too, doesn't support overlap sending, you must enable the blockwise sending of the phone number. You can do this by enabling Force enblock in your routes.
The second setting you must check is Interworking(QSIG,SIP). This feature must be enabled to properly relay supplementary services, like Hold over the SIP Trunk. If this checkbox is unchecked only basic call Information like connect and disconnect will be forwarded by the Gateway.
It is also very important that the correct number is sent to the SIP provider. To ensure this the gateway 'Routing Table' must contain a Clip No Screening configuration, as shown below.
Fax
The FAX was connected via a IP22 to the IP800. When configuring the IP22 you must keep in mind that you will use the analog interface for fax communication. That's why the T.38 codec must be enabled. Additionally an exclusive codec must be selected at the analog interface.
If an innovaphone analog interface is used for sending faxes, STUN must be configured in the GW - interface. If a innovaphone ISDN interface is used for sending faxes, STUN is not needed.
CLIR
To suppress the CGPN for outbound calls a config line option must be activated. Please enter the following lines in your browser:
