SIP Configuration Notes – HELIATel Premium
Use the specific configuration guide below as an example to configure an SV8100 or SL11100/SL1000 PBX for connection to the service described above via SIP trunks.
Recommended Software Versions
| SV8100: CCPU | vC9.00 |  | SL1X00: CCPU | v4.0 |  |
System Programming
The following items should be changed – all other items are considered irrelevant and as such left as default. Screenshots are for example purposes only and will have been taken from the PBX under test but will apply to the other PBXs listed on the cover of the certificate. Any differences in programming will be documented where necessary.
CCPU IP Address

|---|---|---|---|
| Advanced Items > IP/SIP > SIP Trunks > SIP Trunk Assignment | 10-40-01 | IP Trunk Availability | Set to Enabled |
| 10-40-02 | IP trunk Port Count | Set to number of SIP trunks required. Associated IP Trunk Licenses must be installed on PBX. |
VoIP Trunk Type
| Easy Edit | PRG | Item | Setting |
|---|---|---|---|
| Advanced Items > IP/SIP > SIP Trunks > VoIP Trunk Type | 10-03-02 | Trunk Type | Set VOIPU card trunk ports to SIP |
Networking Mode
| Easy Edit | PRG | Item | Setting |
|---|---|---|---|
| Advanced Items > IP/SIP > Blades > Networking Mode > Networking Mode | 10-23-01 | System Interconnection | Set to Enabled |
| 10-23-02 | IP Address | Set to S52.117.200.68 | |
| 10-23-04 | Dial Number | The first digit(s) that will be dialled | |
| 10-28-01 | Domain Name | Set according to customers network requirements | |
| 10-28-02 | Host Name | Set according to customers network requirements | |
| 10-28-04 | UserID | User ID, as supplied by HELIATel Premium | |
| 10-29-14 | Carrier Choice | Carrier Choice set as Carrier B | |
| 10-29-16 | Register Sub Mode | Set to Disabled | |
| 84-13-28 | Audio Capability | G.711_PT | |
| 84-13-32 | DTMF Relay Mode | Set to RFC2833 |
Notes
- DDIs can be configured if required, using the same procedure as for ISDN trunks
- SIP calls are sent “en bloc”. This means that the External Call Inter digit timer (PRG21-01-03) must expire before the call is set up. This can be reduced, but will have an impact on ISDN trunks also. The user can dial # to indicate “end of dialling” instead if required.
- CLI can be sent out using either 21-17 IP Trunk Calling Party Number Setup for Trunks or 21-19 IP Trunk Calling Party Number Setup for Extensions. If nothing is defined against the extension or trunk, or CLI is restricted through further programming, then no outbound CLI is sent.
Network Configuration
If Public IP addresses are assigned to the SV8100 IPLA and VoIP Gateways, then there should be no
network configuration required.
If there is one public IP address assigned, and NAT is used, it is necessary to configure Port Forwarding
on the router:
- Port 5060 should be forwarded to the IPLA IP address
- Port 10020 – 10275 should be forwarded to the VoIP Gateway IP addresses
- NAPT should be enabled in PRG10-12-06 and the Public IP address should be entered into
PRG10-12-07.
Known Limitations/Comments
- The service uses “Networking Mode” which means that the system does not maintain a
registration. This means that the system is unable to determine if the SIP server is available, and
if it is acceptable to set up calls. - The service only supports codec G.711.
- At the time of publishing the service does not support T38 fax mode. Should the carrier add this to the service it will not be added to the certificate until further testing has been completed.
