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@gw03.mytel.net.au
[mytel] host=gw03.mytel.net.au secret=******* username=****** fromdomain=gw03.mytel.net.au fromuser=****** type=friend allow=g729 allow=gsm dtmfmod=rfc2833 [******] context=from-sip host=gw03.mytel.net.au type=friend allow=g729 allow=gsm dtmfmod=rfc2833	;VoIP Extension Password ;VoIP Extension ;VoIP Extension ;VoIP Extension

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.

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

exten => _.,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
