CHAPTER 28 Configuring Supplementary Services
5. Open the IP-to-Tel Routing table (see
then configure a routing rule to route INVITE messages from the remote IP call entity to which
you want to play MoH, to the FXS port. Configure the rule as follows:
● 'Destination Type': Trunk Group
● 'Trunk Group ID': 1 (as configured in Step 3 above)
● Configure a specific matching characteristics, for example, 'Source Host Pattern':
mypizza.com
6. Open the Supplementary Services Settings page (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary > Supplementary Services Settings), and then
in the 'Maximum simultaneous streaming calls' field (MaxStreamingCalls), enter the maximum
number of concurrent calls that the FXS port can service for playing MoH.
7. Click Apply, and then reset the device with a burn-to-flash for your settings to take effect.
You can forcibly stop or start audio streaming on the FXS port(s) through CLI:
■ To start audio streaming:
admin streaming start <FXS Channel>|all
■ To stop audio streaming:
admin streaming stop <FXS Channel>|all

Call Pickup

The device supports the Call Pick-Up feature, whereby the FXS user can answer someone else's
call by pressing a user-defined sequence of phone keys. When the user enters the user-defined
digits (e.g., #77), the incoming call from the other phone is automatically forwarded to the FXS
user's phone.
The feature is applicable only to the Gateway application (FXS interfaces).
However, you can also use this feature for playing MoH to SBC calls. For this
scenario, you need to configure a routing rule between the SBC application (IP-to-
IP Routing rule with 'Destination Type' parameter configured to Gateway) and the
Gateway application (IP-to-Tel Routing table, as described above).
You must configure the 'Maximum simultaneous streaming calls' parameter to a
value greater than 0.
Each FXS port that is used for this audio streaming service must be configured with
its own dedicated Tel Profile, Trunk Group, and IP-to-Tel Routing rule.
Only one coder can be configured for the port. If the device receives an INVITE/re-
INVITE with a coder that is different to the one configured for the Tel Profile, the
device rejects it.
If the external audio streamer is disconnected or powered off, the FXS port
changes to on-hook state and the device stops playing MoH to call parties that are
currently on hold (by sending a SIP BYE).
If the port goes on-hook or the number of concurrent sessions exceed the
configured maximum, the device rejects all streaming sessions with a SIP BYE
response.
If your streaming service is working and you want to modify its configuration, after
you have modified configuration you need to restart the service.
