H.323 and voice services over IP Overview This chapter describes the capability of the 6100 VDR to support IP telephony and the basic procedures for supporting the voice ports using the Command Line Interface (CLI). This chapter contains three sections: • Background information about IP telephony based on H.
CHAPTER 1 About H.323 Note. Vpacket strongly recommends that you use the supplied coding profiles listed in Appendix D for initial configuration and system tests. Only when network quality characteristics have been benchmarked and systematically tested, you can proceed with customizing them. Coding profiles Coding profiles are configuration files that consist of numbered sets of parameters that control the characteristics of the voice and fax traffic over the DSP channels.

CHAPTER 6 Address Translation Parsing Module (ATPM) 46 Vpacket 5100/6100 Series H.
Overview The Address Translation Parsing Module (ATPM) is used to configure a dial plan for a system that is running within an H.323 environment. The ATPM provides a set of utilities to perform these tasks: • Store and retrieve configuration information from Flash. • Delete all configured entries. • Generate a limited number of entries automatically.
CHAPTER 6 Address Translation Parsing Module (ATPM) For example, to update the database you issue the atpm req command: VPacket# telephony tel# atpm req 0005957541 - NMM: ATPM Update Database Granted OK tel# The ATPM database accepts no update requests until the ATPM database signals that changes have been made, so no new translations or Hunt sessions will be accepted. This is to avoid wrong translation due to inconsistent ATPM database.
ATPM Telephone Address to Hunting Group [prefix_number]: Digit to be attached to the beginning of the address before forwarding it. Note that this optional step of attaching a new prefix address is done only after the previous step of stripping some prefix digits on the collected digits. This set of parameters allows for fairly complicated address-mapping schemes to be developed so Vpacket strongly urges that you have a well-developed plan for assigning values designed beforehand. Note.
CHAPTER 6 Address Translation Parsing Module (ATPM) Example: VPacket(telephony)# atpm alist 5715611 Address Hunt Entry Grp_Id Digits Digits strip Address Min Max Prefx Prefix 14085715600 0 11 11 11 None 14085715601 1 11 11 11 None 14085715602 2 11 11 11 None 14085715603 3 11 11 11 None 14085715604 4 11 11 11 None 14085715605 5 11 11 11 None 14085715606 6 11 11 11 None 14085715607 7 11 11 11 None 14085715608 8 11 11 11 None 14085715609 9 11 1
ATPM Telephone Address to Hunting Group In this example, the alist covers all three possible cases for the numbers 408-571-5600 to 408-5715611, twelve numbers which match the VDR physical telephone lines: • The first 12 are incoming, “fully-qualified” numbers, which include the full 10-digits of longdistance and area code. • The second 12 are “in-house” or “intercom” options, which support port-to-port connections. • The third 12 are “local” numbers and support local connections.
CHAPTER 6 Address Translation Parsing Module (ATPM) atpm hdel removes a specific entries in the Hunt group list. Destinations list The ATPM Destination List builds a list (dlist) which provides a mapping from a destination ID to the physical termination of a call using either the Telephony Switching Gateway Module (TSGM) or the H.323 Switch Mode Unit (HSMU).
ATPM Telephone Address to Hunting Group To view the destination list, issue the atpm dlist command and you will see something similar to the following example: VPacket(telephony)# atpm dlist Dest id = 0, Mode = TSGM, TCID = 0 Dest id = 1, Mode = TSGM, TCID = 1 Dest id = 2, Mode = TSGM, TCID = 2 Dest id = 3, Mode = TSGM, TCID = 3 Dest id = 4, Mode = TSGM, TCID = 4 Dest id = 5, Mode = TSGM, TCID = 5 Dest id = 6, Mode = TSGM, TCID = 6 Dest id = 7, Mode = TSGM, TCID = 7 Dest id = 8, Mode = TSG
