Chapter 19-Gateway Calls

For more details on Dialing Rules definition in the CMA, see the Polycom CMA System Operations Guide, “Dial Rule Operations”.

Gateway Redial or Redialing Gateway Calls

Additional Redial options and IVR messages have been included for Gateway Calls to

numbers that are wrong, adding functionality to the RMX’s Gateway capabilities when used in conjunction with communication servers (H.323, SIP, ISDN) such as Polycom’s CMA and DMA.

Guidelines

•Redial with IVR is supported:

—With both MPMx and MPM+ cards.

—In CP environments only.

—For H.323, SIP and ISDN calls.

—When using the RMX’s Inviting Participants using DTMF functionality.

•Redial with IVR is not supported:

—When using PCM’s Invite Participant functionality.

—Dialing multiple destination numbers.

Redial on Wrong Number

In previous versions, calls to wrong numbers were disconnected, with no redial attempts or IVR messages.

In this version, an IVR message is played requesting the user to enter a new number, followed by up to five redial attempts. If all redial attempts fail, the user is alerted by an IVR message that the dialed number is unreachable, followed by reorder tone and disconnection.

Wrong Destination Number

•The number of re-dial attempts is controlled by the WRONG_NUMBER_DIAL_RETRIES System Flag.

The default number of redial attempts is 3. To modify the number of redial attempts, manually add the flag to system.cfg and set its value to the number of redial attempts required.

The flag value range is 0-5. A flag value of 0 means that no redials are attempted. For more information about System Flags, see "Manually Adding and Deleting System Flags” on page 22-18.

•Redial attempts follow the same order as defined in the Gateway Profile: H.323, followed by SIP, followed by ISDN. For more information about Gateway Profiles and Gateway Dial out Protocols, see "Defining the Gateway Profile” on page 19-18.

•Redial on Wrong Number is activated if a Gateway Call fails, for all defined protocols, for any reason or combination of reasons listed in Table 19-3.
