Mytel provides the following information, as a guide only, to assist you in configuring up your SIP or IAX trunk with Asterisk.

Any further support (i.e. local phone configuration, dial plans, etc) would be charged at Mytel's Asterisk Consultancy rates.

How to setup a SIP Trunk with Mytel

Mytel allows you to connect to your SIP Account as SIP Trunk using the open-source PBX Asterisk. To do this, the following entry will need to be made in your 'sip.conf' file.

register => <username>:<password>@sip<state code>.mytel.net.au
[mytel] host=sip<state code>.mytel.net.au secret=<password> username=<username> insecure=invite fromdomain=sip<state code>.mytel.net.au fromuser=<username> type=peer allow=all dtmfmode=rfc2833 context=incoming-voip

Where your Mytel VoIP Extension is used as the value for username, fromuser and substituted for username in the register setting. Also, your Mytel VoIP Extension password is used as the value for secret and substituted for password in the register setting.

The setting for state code depends on your location; it is the same as the telephone prefix for your state, e.g. 02 for New South Wales, 03 for Victoria and Tasmania, 07 for Queensland and 08 for Western Australia, South Australia and Northen Territory.

In order to make a call using your newly created Mytel SIP trunk place the following entry in your 'extensions.conf' file,

exten => _X.,1,Dial(SIP/mytel/${EXTEN}) exten => h,1,Hangup

It is also recommened that you assign a static IP address to the PC running Asterisk. Finally, you are required to open up some ports in your firewall and/or create port forwarding rules in your router. How to achieve this will vary depending on what hardware you have. Please open/forward the following ports to the IP address of you Asterisk PC.

SIP: RTP:

TCP/UDP 5004 - 5082 UDP 10000 - 20000

How to setup a IAX Trunk with Mytel

To configure your IAX account to be used with Asterisk, please enter the following into your 'iax.conf' file.

register => <username>:<password>@iax<state code>.mytel.net.au
[mytel] host=iax<state code>.mytel.net.au secret=<password> username=<username> fromuser=<username> type=peer dtmfmode=rfc2833 trunk=no qualify=yes allow=all [<username>] context=incoming-voip host=iax<state code>.mytel.net.au type=user dtmfmode=rfc2833 trunk=no qualify=yes allow=all

Replace username with your Mytel IAX Account Name and password with your Mytel IAX Account Password in the register string.

The setting for state code depends on your location; it is the same as the telephone prefix for your state, e.g. 02 for New South Wales, 03 for Victoria and Tasmania, 07 for Queensland and 08 for Western Australia, South Australia and Northen Territory.

In order to make a call using your newly created Mytel IAX trunk place the following entry in your 'extensions.conf' file.

How to achieve this will vary depending on what hardware you have. Please open/forward the following port to the IP address of you Asterisk PC.
