There are several Linux tools to monitor the system load and other performance indicators: 

No. MSP cannot play media in the middle of a call setup. See the PBX related questions in the FAQ list for more information.

Yes. MSP can be used as generic least cost routing gateway for traffic originating and terminating to outside parties. Please contact AG Projects support for your particular setup.

Some PBX related functions are available through the inherent platform design (for example vociemail, call diversion, do not disturb, incoming caller accept/reject, parallel forking).

CDRTool 6.2.1 has full replication monitoring and can generate in real time repair instructions for your particular MySQL replication setup.

MSP simply transports the media between SIP end user devices. Any echo related problems are caused by the SIP devices and cannot be fixed in the SIP platform itself.

Beware that OpenXCAP server needs to run on a host that has Internet connectivity. This is due to a constraint imposed by the underlying libxml library that will try to connect to w3c website on startup to retrieve the xml schemas used for validating xcap documents

MSP automatically adds P- headers and Remote-Party-Id headers with proper anonymous indication to the PSTN gateway. The gateway must support these header too.

 

 

MWI (message waiting indicator) is used to indicate whether there are new messages on the voicemail server. This option is available if the SIP account has storage of voicemail message on the server enabled. By default all messages are sent by email and no MWI is generated.

 

Yes. Provision the rates again, or add specific historical rates in the rates_history tables. Locate the calls you want to re-rate using CDRTool search  facility and select re-Normalize. All selected calls will have the price recalculated.

There are two methods to transmitt a fax using SIP:

MSP deals automatically with NAT traversal by relaying all traffic through its SIP and MediaProxy. If this does not work, the reasons are likely outside the control of MSP and you must solve this at the point where the NAT traversal breaks.

No, you do not need STUN in order to traverse NAT.

 

 

MSP is designed to work on the public Internet and use ENUM as a default routig engine for telephone numbers. Because of this design its is always easy to setup peerings with both open networks (nothing to do, it just works out of the box) or closed networks for which you must manually manage the peering relations.

Typically when you create an account on the platform you do create mandatory:

You may use both SIP Message (paging mode) or the recently added MSRP protocol (session mode). To traverse NAT, MSP provides a MSRP relay server. Please contact AG Projects for an upgrade if your platform does not have yet an MSRP relay.
