Guideline to setup SIP trunk with ZONETEL

It is quite often to have customers inquiring the sip trunk configuration issues with ZONETEL.  Here is some useful information for reference.  Usually the tricky part is with NAT and firewall ports, which leads to one-way audio or no audio at all.
 

Sample sip.conf (it applies to asterisk 1.4.x)

[general]

Defaultexpiry=600

 

[zonetel]

Username=<provided by zonetel>

Fromuser=<provided by zonetel>

Secret=<provided by zonetel>

Host=<the sip register server provided>

Type=friend

Qualify=yes

Insecure=very

canreinvite=no

Disallow=all

Allow=alaw

Allow=ulaw

 

 

Ports required

Of course, your firewall needs to allow 5060 tcp/udp for sip signaling

And have to make sure that UDP ports are also allowed to the zonetel subnet
