• Ensure that both the sender and recipient are 
registered to the UMTS network. If you invite someone 
to a sharing session and the recipient’s device is turned 
off, is not within UMTS network coverage, or does not 
have Video sharing installed or person-to-person 
connections set up, the recipient does not know that 
you are sending an invitation. However, you receive an 
error message that the recipient cannot accept the 
invitation.
Settings
Person-to-person connection settings
A person-to-person connection is also known as a Session 
Initiation Protocol (SIP) connection. The SIP profile 
settings must be configured in your device before you can 
use Video sharing. Setting up a SIP profile allows you to 
establish a live person-to-person connection to another 
compatible device. The SIP profile must also be 
established to receive a sharing session.
Ask your network operator or service provider for the SIP 
profile settings, and save them in your device. 
Your network operator or service provider may send you 
the settings over the air or give you a list of the needed 
parameters.
If you know a recipient’s SIP address, you can enter it on 
the person’s contact card. Open Contacts from your 
device main menu, and open the contact card (or start a 
new card for that person). Select Options > Add detail > 
SIP or Share view (the correct option depends on the 
network operator). Enter the SIP address in the format 
username@domainname (you can use an IP address 
instead of a domain name).
If you do not know a SIP address for the contact, you can 
also use the already saved phone number of the recipient 
including the country code, for example +358, to share 
video. If the phone number saved in Contacts does not 
include the country code, you can enter the number 
including the country code when sending the invitation.
UMTS connection settings
To set up your UMTS connection, do the following:
• Contact your service provider to establish an 
agreement for you to use the UMTS network.
• Ensure that your device UMTS access point connection 
settings are configured properly. For help, 
see “Connection”, p. 99.
Share live video and video clips
To receive a sharing session, the recipient must install 
Video sharing and configure the required settings on their 
compatible mobile device. You and the recipient must both 
be registered to the service before you can start sharing.
