Client type Uses to the external interface of the SBCE
TLS SRTP Audio SRTP Video
If the mobile client using TLS and/or SRTP will be used to roam from the network on
the ASBCE's external interface to the network on the IP Office side of the ASBCE, the
transport medium will have to be changed while the mobile client is connected to the
network on the IP Office side. IP Office 9.0 does not support direct SRTP connections
to these mobile clients and TLS is ONLY supported on the OneX Mobile Preferred
VOIP Client for Android.
• If Media or Signaling QoS are required, they must be configured on the SBCE as the
SBCE does not pass through.
• Customer firewall configuration requires forwarding of video/audio signaling and media
ports. SIP ALG’s should be disabled on any firewalls.
• For troubleshooting the best rules to follow are to look at Alarms/Incidents and take a
packet capture to determine if the issue is on the SBCE. If further debugging is required,
enable debug logs and get the appropriate elogs.
• If doing remote worker and trunking on the same SBCE, you use a second set of IP
addresses on the SBCE for trunking. See the SBCE documentation and application notes
on configuring SBCE for trunking.
• Review SBCE, IP Office, and endpoint release notes for fixes, limitations, and
workarounds.
