switch (for US telcos, this value should be at least 3-4s). If is “PIN”, theSPA then prompts the caller to enter the PIN number. If the given PIN matches one of values, the SPA plays the Dial Tone to the FXO port and is ready to accept digits of the VoIPtarget number from the PSTN caller. The collected digits will be processed by the dial plan associatedwith the PIN number. If is “none”, the SPA plays the Dial Toneimmediately right after it auto-answers the PSTN call; the is used for allPSTN Callers for this case. Note that the chosen dial plan for any PSTN caller cannot be “none”.If the caller enters a valid PSTN number according to the chosen dial plan, the PSTN generates anINVITE to establish the VoIP call leg via the VoIP2 interface configured under the [PSTN Line] tab.The From header of the INVITE will be the VoIP2 account, or substituted with the PSTN Caller-IDname and number if they are sent by the PSTN switch and decoded successfully by the SPA and is set to “yes”. Furthermore, the SPA will prepend the PSTN Caller-IDname and number with the prefixes configured in and respectively.Notes:- PSTN-To-VoIP Gateway service can be globally disabled by setting to “no”. In that case, the SPA will not auto-answer any PSTN calls- If the ([PSTN Line] tab) is “no”, or VoIP2 is not successfully registered and ([PSTN Line] tab) is “no”, or the Ethernet link is down, the SPA will not autoanswerthe PSTN call as if is set to “no”.- Speed dial is allowed by the PSTN caller; 8 speed dials can be configured under [PSTN User] tab- You can “forward” PSTN callers unconditionally with a hotline or warmline rule in the chosen dialplan, after the caller is successfully authenticated- SPA supports selective call forwarding or blocking of PSTN callers such that a PSTN caller iseither “forwarded” to a fixed VoIP number or “barred” from accessing the VoIP gateway (the callwill not be answered by the SPA in the latter case). Selective call forwarding and blockingfunctions are configured under [PSTN User]. SPA does not authenticate the PSTN caller if he isconfigured to be forwarded.Below is the pseudo code for accepting a PSTN caller for VoIP gateway service.If (PSTN Caller ID Pattern Blank or PSTN Caller-ID Matches a PSTN Caller-ID Pattern) {Auto Answer (Off-Hook FXO Port)If (PSTN Caller-ID in PSTN Access-List or Authentication Disabled) {start_service:Play Dial ToneCollect VoIP Target Number Digits from CallerIf (Target Number Valid) {Start VoIP Call}Else {Play Reorder ToneHang Up}}Else {Get PSTN PIN from CallerIf (Valid PIN) {Goto start_service}Else {Play Reorder ToneHang Up}© 2003 - 2004 Sipura Technology, Inc Proprietary (See Copyright Notice on Page 2) 49
