12 CONVENTIONAL IP NETWORK / 12.7 SIP Phone172FUNC (E)/ Ver 2.00Configuration DescriptionSIP User ID SIP User ID is the ID for SIP connection by the repeater to a SIP Phone Server.By using a configured SIP User ID, Registration to a SIP Phone Server is performed bythe repeater. Therefore, the same ID as the SIP User ID configured for the repeater needsto be registered beforehand for the SIP Phone Server.Two SIP User IDs can be configured in DMR Mode, for slot 1 and for slot 2. If a callrequest is received from a SIP Phone, the repeater delivers the Phone Call afterspecifying the slot that corresponds to a SIP User ID.In NXDN Mode, one SIP User ID can be configured for one repeater.Even if a SIP User ID is registered, if Registration to a SIP Phone Server is not executedfor the SIP User ID, communication cannot be done by using the SIP User ID.SIP User ID Name SIP User ID Name is the function to configure the name for a SIP User ID.PSTN Prefix / PABXPrefix(DMR Mode Only)PSTN Prefix / PABX Prefix is the identifier to determine whether a Paging Call made fromthe transceiver is addressed to a SIP Phone.A call to a SIP Phone from the transceiver is made by using a Paging Call. The repeaterdetermines whether the destination configured for a Paging Call is a SIP Phone. PSTNPrefix and PABX Prefix digits are compared from the beginning of an ID of a Paging Call,and if they match, the repeater determines the call is addressed to the SIP Phone. Referto Table 12-12 and Table 12-13 for details.Two PSTN Prefix/ PABX Prefix can be configured in DMR Mode, for slot 1 and for slot 2.The repeater compares the first one digit to up to four digits of the ID specified by aPaging Call with PSTN Prefix and PABX Prefix. If the comparison result matches, thePaging Call is treated as a call addressed to a SIP Phone.The comparison of the ID of the Paging Call to Prefix is performed starting from PSTNPrefix, and if no match is made, the comparison is made to PABX Prefix.The number of digits for comparison of the ID of the Paging Call to PSTN Prefix or PABXPrefix follows each configuration in PSTN Prefix and PABX Prefix.If a Paging Call ID and PSTN Prefix match, the repeater notifies the caller ID of a relayedaudio signal received from a SIP Phone as FFFEE0 after the call is established.If a Paging Call ID and PABX Prefix match, the repeater notifies the caller ID of a relayedaudio signal received from a SIP Phone as FFFEE1 after the call is established.
