Note: failowering will occur with increased thresholds (more slowly) if the priority between the routing directions (SIP servers) is more than 100.4.4.15. Channel reservationSkip this chapter if you are not using VoIP-GSM gateways.Best quality (ASR and ACD) SIM channels can be reserved for sip or h323 originated calls.In the sim table the reserverfor field can have the following values:0=cannotreserve: this channel will not be reserved1=sip: always reserve only for SIP (manually assigned)2=h323: always reserve only for H323 (manually assigned)3=ISDN: always reserve only for ISDN (manually assigned)4=dynamic: can be allocated by the server dynamically (hourly check) -this is the default value5=sipdynamic: allocated automatically for SIP6=h323dynamic: allocated automatically for H3237= ISDNdynamic: allocated automatically for ISDNFor every simpacket you can restrict the maximum allowed reservations by the maxalloc field. (useful to not reserve all channel from the same simpacket)To setup the channel reservation use the following configuration values (mserver, simplatform config):-reserveforh323: reserve capacity for h323. reservations will be disabled if less than 1-reserveforsip: reserve capacity for sip . reservations will be disabled if less than 1By example if you set the reserveforsip field to 5, you can be sure that 5 channels always remain free to be used by calls received with SIP protocol (H323originated calls didn’t consume all your channels)4.4.16. Number portabilityIf the portednumber table is populated, the server will change the original caller number prefix to the new operator prefix, and will route the callaccordingly.You can set the ported numbers form the MManage “Number Portabilty” form or you can automate the process by programmatically changing thetb_portednumbers database table.You can control the server number portability handling by the “checknumport” global configuration:0=not check1=check for changed prefix2=check for changed number3=check for changed domain4=check allThe fwdtootherdomains must have to be set to at least 1 for domain routing to have effect.
