Command Reference Guide
ip sip
Use the ip sip command to enable the AOS Session Initiation Protocol (SIP) stack and to specify the
protocol and port used by the SIP stack. When the SIP stack is enabled, memory is allocated for SIP
functionality. Use the no form of this command to disable the SIP stack and free the memory allocated to
the stack. Variations of this command include:
ip sip
ip sip tcp
ip sip tcp <port>
ip sip udp
ip sip udp <port>
Syntax Description
tcp
udp
<port>
Default Values
By default, the SIP stack is enabled on AOS voice products and disabled on AOS data products. The SIP
stack operates using UDP on port 5060 if no protocol or port are specified. If a protocol is specified, but no
port is specified, the SIP stack uses port 5060.

Functional Notes
By default, the AOS SIP application layer gateway (ALG) is enabled. This ALG allows the firewall to
examine all SIP packets it identifies and to maintain information of SIP transmissions on the network based
on the SIP header. The SIP ALG requires the use of the SIP stack and the SIP proxy server in order to
properly route SIP calls and maintain the SIP information. For more details on the operation of SIP and the
SIP ALG, refer to the command
For proper SIP operation, the firewall must also be configured to allow for dynamic holes for the Realtime
Transfer Protocol (RTP) and the Realtime Transfer Control Protocol (RTCP) traffic associated with SIP
calls between user agents. This functionality must be manually enabled. For more details on enabling this
functionality, refer to the command
The SIP stack is used for many AOS features, including Transparent Proxy and Voice Quality Monitoring
(VQM) Reporting. Refer to the configuration guides available online at
for more information about SIP operation with specific features.
