Attend Transfer
There is a hold action before sending REFER message with current behavior of attend
transfer. However, the transfer behavior will be processed by some server. That`s why
some server will have the problem of attend transfer. Our solution is to not sending the
hold before REFER message. So it should have a flag to this feature to keep the former
behavior and also meet this server requirement.
Feature Activation
Via APS
APS in [sip] section of both Common and Specific-MAC config files with the
new parameter – Hold_bf_Att_Trans.
Hold_bf_Att_Trans = 0 with hold behavior in attend transfer
Hold_bf_Att_Trans = 1 without hold behavior in attend transfer
[sip]
…
Hold_bf_Att_Trans =0
…
Via Telnet
To configure, open a command line console, and telnet the phone:
Example:
Hold_bf_atttrans is set to 1 (sip set hold_bf_attrans 1)
Then type commit and then activate to apply the change.
