Connect Avaya IP Office to a Kenyan SIP Trunk (Sautikit)
Add a Sautikit Kenyan number to Avaya IP Office as a SIP Line: ITSP proxy, send port 5080, SIP credentials, SIP URI, incoming call route and ARS.
Add a Sautikit Kenyan number to Avaya IP Office as a SIP Line: ITSP proxy, send port 5080, SIP credentials, SIP URI, incoming call route and ARS.
An Avaya IP Office system can use a Kenyan Sautikit number as its SIP trunk. In IP Office Manager, create a New SIP Line with ITSP Domain Name and ITSP Proxy Address sip.sautikit.com, Layer 4 Protocol UDP and Send Port 5080. On SIP Credentials, add your Sautikit SIP username (as User name and Authentication Name) and password with Registration required ticked. Add a SIP URI that uses that registration, an Incoming Call Route for the line group, and a short code or ARS entry for outbound calls in +254 format. You also need enough SIP Trunk Channels licences. The number costs KES 500 a month, inbound calls are free and outbound calls cost KES 3.00 a minute billed per second.
| IP Office field | Value |
|---|---|
| ITSP Domain Name | sip.sautikit.com |
| ITSP Proxy Address | sip.sautikit.com |
| Layer 4 Protocol | UDP |
| Send Port | 5080 |
| Listen Port | leave at 5060 |
| User name | your Sautikit SIP username |
| Authentication Name | your Sautikit SIP username (same value) |
| Password | your Sautikit SIP password |
| Registration required | ticked |
| Codecs | G.711 U-law, G.711 A-law first |
Under System > LAN1 > VoIP, make sure SIP trunks are enabled. If the IP Office sits behind NAT, set the public IP and firewall type under LAN1 > Network Topology.
In the navigation pane, right-click Line and choose New > SIP Line. Note the line number; you will use it as the incoming and outgoing group below.
sip.sautikit.com.sip.sautikit.com, Layer 4 Protocol = UDP, Send Port = 5080, Use Network Topology Info = LAN1. Leave Calls Route via Registrar on.Port 5080 is the setting most often missed: IP Office defaults the send port to 5060, and Sautikit listens on 5080.
On the SIP Credentials tab, click Add and enter the User name, Authentication Name and Password from the table. Tick Registration required. Set Expiry to 60 minutes or less.
On the SIP URI tab (under Call Details on R12), click Add:
In Sautikit: open the number and set Forward to the IP Office device's extension. Calls to your number now go to the SIP Line.
In IP Office: create an Incoming Call Route with Line Group ID = the line number, and set the destination (a hunt group, auto attendant or user) on the Destinations tab.
Add a short code or ARS entry that sends external calls to the line group and presents them in E.164: for example, turn 0XXXXXXXXX into +254XXXXXXXXX. Sautikit shows your Sautikit number as caller ID on every outgoing call.
Merge the configuration, check the line shows as registered in System Status, then call your mobile from an extension and call the Sautikit number from your mobile.
Avaya Aura systems connect to SIP providers through an Avaya SBC for Enterprise (SBCE) rather than registering from Communication Manager itself. On the SBCE, add a Trunk Server profile for sip.sautikit.com, port 5080, UDP, enable authentication with your Sautikit SIP username and password, and turn on registration. Your Avaya partner will route calls from Session Manager to that SBCE profile.
The line does not register. Check Send Port 5080, UDP and the proxy address spelling. Check the credential has Registration required ticked.
Registration fails with an authentication error. User name and Authentication Name must both be the generated Sautikit username, not your phone number.
Calls stop at two or three at once. Check your SIP Trunk Channels licence instances.
Outbound calls are refused. Destinations must reach Sautikit in +254 format, and your wallet needs credit.
Yes. The SIP Line's SIP Credentials tab has a Registration required option, and the SIP URI is tied to that registration.
5080 over UDP at sip.sautikit.com. Set it as the SIP Line's Send Port.
Avaya licenses SIP trunk calls by channel through the SIP Trunk Channels licence. On Sautikit there is no trunk fee: the number is KES 500 a month, inbound calls are free and outbound calls are KES 3.00 a minute billed per second.
