You can specify one or more trusted IP addresses on the IP phone, or configure the IP phone to receive and
handle the URI from any IP address.
10.27.2 Supported SIP Notify Message
In addition, ALE Myriad Series phones can perform the specified action immediately by accepting a SIP
NOTIFY message with the “Event: ACTION-URI” header from a SIP proxy server. The message body of the
SIP NOTIFY message may contain a variable named as “key” and a variable value, which are separated by
“=”.
This method is especially useful for users who always work in the small office/home office where a secure
firewall may prevent the HTTP or HTTPS GET request from the external network.
Note: If you want to only accept the SIP NOTIFY message from your SIP server and outbound proxy server,
you have to enable the Accept SIP Trust Server Only feature.
If you use SIP NOTIFY message method, you do not need to specify the trusted IP address for action URI.
However, you should enable the IP phone to receive the action URI requests. When the IP phone receives a
SIP NOTIFY message with the “Event: ACTION-URI” header from a SIP proxy server for the first time, the
LCD screen also prompts the message “Allow remote control?”. Press the “OK” soft key on the phone to
allow remote control.
Example of a SIP Notify with the variable value (OK):
NOTIFY sip:[toUsername]@[remote_ip]:[remote_port];transport=[transport] SIP/2.0
Via: SIP/2.0/[transport] [local_ip]:[local_port];branch=[branch]
From: <sip:[fromUsername]@[remote_ip]:[remote_port]>;tag=452352542352354325
To: <sip:[toUsername]@[remote_ip]:[remote_port]>;[peer_tag_param]
Call-ID: [call_number]@[local_ip]
CSeq: [cseq+1] NOTIFY
Allow-Events: message-summary, refer, dialog, line-seize, presence, call-info, as-feature-event, calling-
name, ua-profile
Max-Forwards: 70
Contact: <sip:[fromUsername]@[local_ip]:[local_port];transport=[transport]>
User-Agent:
Event: ACTION-URI
Content-Type: message/sipfrag
Content-Length: [len]

10.27.3 Variable Values List
The ALE Myriad Series phones also support a combination of the variable values in the URI, but the order of
the variable value is determined by the operation of the phone. The valid URI format is shown below:
http(s)://<phoneIPAddress>/servlet?key=variable value[;variable value].
Variable values are separated by a semicolon from each other.
Note: For M8, (F_) CONFERENCE/ F_ CONFERENCE_ LONGPRESS are replaced by (F_) HEADSET/ F_
HEADSET_ LONGPRESS.
