Introduction Support Level 2
The level 2 support is the first instance where the user's telephony problems are handled that a user cannot solve himself. Additionally the level 2 supporter must be able to detect if the user problem is a "single" problem or if there is a large scale problem, that produces the same problem for multiple customers, e.g. data transfer problems in the Internet so that no VoIP call signaling is possible.
The level 2 supporter must be aware of the complexity of a VoIP system and the multitude of telephony solutions on the user side. Further he needs an understanding of:
- IP networking
- VoIP protocols SIP for signaling, SDP and RTP for speech transmission.
Overview of a VoIP system and the multitude of user telephony solutions:
The level 2 supporter faces problems with the following layers:
- Equipment
- IP data transfer
- Telephony service
And each of this layer can be located into the following raw areas:
- Customer/User site
- Internet Service Provider ISP
- Telephony Provider
This layer and dividing into areas produces a "3x3 Support Matrix":
Within this "3x3 Support Matrix" the supporter can:
- advice the customer what to do when the problem is located in the nodes 1-T, 1-D and 1-E
- check the customer configurations on the VoIP Switch, node 3-T, and, if he has operator rights, adjust configurations.
For the other cases the level 2 supporter must be able to identify if:
- the user must contact his ISP, due to possible Internet access problems
- the VoIP System administrator must be involved, due to possible telephony service problems
- Hint:
- These cases indicate mostly large scale problems within the VoIP system!
Best Practice for Handling an User Problem
Best Practice |
|
Analyzing the Customer Problem
Identifying the User Problem
The supporter finds here instructions how to handle a user's telephony problem and to find out the problem area.
Cross Check the User Inputs
Check the Big Picture
Solving the Customer Problem
Solve Problem: The User Device does not Register
Instruction how to find out and solve why the user's device cannot register, e.g.:
- Defect or not powered user device
- User device not correct connected to the IP network
- User device not correct configured
Solve Problem: Incoming Connections are Failing
Instruction how to solve failing incomming connections, e.g.:
- User device not correctly registered
- Wrong calling number
- User device not correct configured
Solve Problem: Outgoing Connections are Failing
Instruction how to solve failing outgoing connections, e.g.:
- User device not correctly registered
- Wrong called number
- User device not correct configured
Solve Problem: Irregular Connection Release
Instruction how to solve irregularly released user connections, e.g.:
- Failing Session Timer
Solve Problem: Disturbed Speech Transmission
Instruction how to solve disturbed speech transmission, e.g.:
- Short interruptions during the connection
- No transmission in one direction from the beginning of the connection
- No transmission in both directions from the beginning of the connection
Solve Problem: Disturbed FAX Transmission
Instruction how to solve interrupted FAX transmission, e.g.:
- Fax transmission doesn't start
- Not all pages are transmitted
Solve Problem: DECT Multi-Cell Handsets are not Working
Instruction how to solve problems with DECT Multi-Cell handsets, e.g.:
- Hand over from cell to cell not working
- Bad speech quality
