A SIP profile is a template that comprises common SIP settings. You must assign a SIP profile for every SIP trunk and SIP device in your network. When you configure a SIP profile and then assign that profile to a SIP trunk, or a SIP device, the system applies the configured SIP settings to that trunk or device.
Without the SIP profile, you would have to configure SIP settings individually for every SIP trunk and SIP device in your network. However, you can use the SIP profile to assign many SIP settings, such as the following:
MTP Telephony Payload Types
SIP header details
Timers and counters for SIP messages
SDP transparency profiles for SDP interoperability
SIP Normalization and Transparency scripts for SIP lines
SIP OPTIONS settings
SIP Early Offer support
Call Pickup URIs
Configure SIP Profiles
Use this procedure to configure a SIP profile. Upon installation, Cisco Unified Communications Manager contains a group of default SIP profiles. You can either edit any of the default SIP profiles or create new SIP profiles.
From Cisco Unified CM Administration, choose Device > Device Settings > SIP Profile.
Perform either of the following steps:
To edit an existing profile, click Find and select the SIP profile.
To create a new profile, click Add New.
If you want your SIP phones and trunks to support both IPv4 and IPv6 stacks, check the Enable ANAT check box to enable Alternate Network Address Types. With this configuration, SIP signaling from the device or trunk can include both an IPv4 address and an IPv6 address simultaneously.
If you want to assign an SDP transparency profile to the devices and trunks that use this SIP profile, from the SDP Transparency Profile drop-down list box, choose the profile.
If you want to assign a normalization or transparency script to SIP devices that use this SIP profile, from the Normalization Script drop-down list box, select the script that you want to apply.
Complete the remaining fields in the SIP Profile Configuration window. For help with the fields and their settings, refer to the online help.
What to Do Next
In order for a trunk or device to be able to use a SIP profile, you must associate the profile to a trunk or device in the Trunk Configuration or Phone Configuration windows.
