Please Note

Mytel provides the following information, as a guide only, to assist you in configuring up your SIP or IAX trunk with Asterisk@Home. These configurations have been tested using Asterisk@Home 2.8 built on a PC behind NAT. As every network is slightly different, there is no guarantee that the following configuration will work on your PC. Mytel offers limited free support for customers running Asterisk@Home, the extent of which is limited to troubleshooting connection issues. Any further support (i.e. local phone configuration, dial plans, etc) would be charged at Mytel's Asterisk Consultancy rates.

While we provide configuration information for SIP and IAX, we strongly recommend customers running Asterisk@Home considering upgrading to an IAX plan. We also strongly recommend all customers using Asterisk@Home in a business environment change to the base Asterisk install.

How to setup a SIP Trunk with Mytel

To use your SIP account with Asterisk@Home, you will need to add a SIP Trunk. The information you are required to enter is shown below.

General Settings
Outbound Called ID:	<username>
Maximum channels:	2
Outgoing Settings
Trunk Name:	mytel
PEER Details:	allow=g729&gsm dtmfmod=rfc2833 fromdomain=sip<state code>.mytel.net.au fromuser=<username> host=sip<state code>.mytel.net.au insecure=very nat=yes secret=<password> type=friend username=<username>
Incoming Settings
USER Context:	blank
USER Details:	blank
Registration
Register String:	<username>:<password>@sip<state code>.mytel.net.au/<username>

Replace username with your Mytel VoIP Extension Number, and password with your Mytel VoIP Extension Password.

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.

You are also required to make a change to your extensions.conf configuration file. This can be done using the Config Edit module. Please remove the entry under the [from-sip-external] entry and replace with the following, so that your [from-sip-external] entry now looks like:

[from-sip-external] exten => <username>,1,Goto(from-trunk,${EXTEN},1)

Once again, replacing username with your Mytel VoIP Extension Number.

It is also recommened that you assign a static IP address to the PC running Asterisk@Home. 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@Home PC.

SIP:	TCP/UDP 5004 - 5082
RTP:	UDP 10000 - 20000
