Re: [Equipment] Useful Sipura tricks...SPA2K and SPA3K
I’m not sure if this qualifies as a “trick”, or just a combination or iteration of utilizing the power of the SPA’s.
My office setup. Each of the SPA’s is connected to a two line phone, and the SPA’s are on the same LAN. I have a fixed IP for a WAN address, and set the SPA’s also to a fixed internal IP. A variation of this procedure may also work with a dynamic WAN IP if utilizing something like DynDNS.org, if supported by your router.
The SPA3K is set up with Broad Voice on Line 1, port 5060, and Delta Three on the PSTN Line, port 5061. The SPA2K has FWD on line 1, port 5062, and Voice Pulse Connect on Line 2, port 5063. Only the Broad Voice line accepts an incomming call. The other lines are outgoing only.
The objective is effectively a direct dial hot line form the phone attached to the SPA2K to the SPA3K PSTN Line.
On the SPA3K SIP Tab, enable “Send Resp To Src Port” down by the STUN settings. I’m not sure if the is required, but it allows both calls to my FWD and IPKall numbers to ring the SPA3K Line 1 directly.
On the Line Tab’s of each ATA adapter ensure that “Use DNS SRV” and “DNS SRV Auto Prefix” is set to no. I also have enabled “Make Call Without Reg” and “Receive Call Without Reg” on both adapters.
The real power of both the SPA’s is in the dial plan.
For the SPA3K, add:
to the Line 1 dial plan. On the PSTN Line, add:
to “Dial Plan 1”. You could use any default area code. On the VoIP To PSTN Gateway Setup, set “One Stage Dialing” to yes. Set the “Line 1 VoIP Caller DP”, “Line 1 Fallback DP”, and “VoIP Caller Default DP” to 1. Add your WAN IP address to the “VoIP Access List”.
For the SPA2K, for the Line 1 and Line 2 dial plans add:
<#0:><:User ID SPA3K PSTN Line@Your WAN IP Address:5061>
911<:User ID SPA3K PSTN Line@Your WAN IP Address:5061>.
The result is that dialing #0 from any of the three VoIP Lines results in a PSTN dial tone, and all calls to 911 from the SPA2K are now automatically dialed from the PSTN Line on the SPA3K. I did make a test call to 911 form the SPA2K, and it does work.
I’m still thinking about PSTN Line access security, but for me it’s generally not an issue, as there is no long distance provider set up through the phone company, and the dial plan restricts PSTN calls to the local area code. It works for me, my office set up, and the way that the phones are used. Any comments, criticism or suggestions would be appreciated. |
