H.323 LRQ RAS Retransmission Configuration

There is no configuration for H.323 LRQ alternate routing; it is enabled by default. You do, however, need to set the ras-tmo and maxRasRetries options to set the timeout period.

If you want to set a maximum number of consecutive LRJs to be received from a session agent, you need to add the max-lrj value to an H.323 session agent’s options parameter.

To configure the number of seconds before the Oracle® Enterprise Session Border Controller retransmits a RAS message:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal

2. Type session-router and press Enter.

   ORACLE(configure)# session-router

3. Type h323 and press Enter.

   ORACLE(session-router)# h323
   ACMEPACKET(h323)#

4. options—Set the options parameter by typing options, a Space, the option name ras-tmo=x (where X is number of the seconds that the Oracle® Enterprise Session Border Controller waits before retransmitting a RAS message; default is 4) with a plus sign in front of it, and then press Enter.

Set the maxRasRetries option in the same way; here, X is the maximum number of times the Oracle® Enterprise Session Border Controller retransmits the RAS; default is 1).

ORACLE(h323-stack)# options +ras-tmo=6
ORACLE(h323-stack)# options +maxRasRetries=2

If you type options and then the option value for either of these entries without the plus sign, you will overwrite any previously configured options. In order to append the new option to the h323 configuration’s options list, you must prepend the new option with a plus sign as shown in the previous example.
