I have an SPA921 IP phone at a remote site that is pointing to an SPA3102 gateway that has an old analog phone attached to it. We can successfully dial each other and hear just fine. The problem that I am currently having is that when I want to dial 9 to get out I immediatly get a fast busy. My current dialing plan on my SPA921 phone is listed below -
(1234<:@123.123.123.12>|<9,:><:@123.123.123.12:5060>)
Right now if I dial 1234 I can ring the analog phone attached to the SPA3102. However, dialing 9 immediatly gives me a fast busy signal. Is there something that I am missing?
Thanks! :)

Thanks for the quick reply. In your document you mention that I should start by registering the line and pstn tabs to the itsp. I have no Internet Tele Service Provider. We're just connected through a DSL line to a home PSTN line.
Am I misunderstanding something?

You don't have to have the line(s) registered. That guide is for the general user. In your case you would just set it so you could make calls without registration. You would still set it up for 2 stage dialing, however.

Your dial plan should look something like this (assuming that you are using port 5061 for the PSTN line on the SPA3102):
(1234<:@123.123.123.12>|9,xx.<:@123.123.123.12:5061>)
Hope that helps.

I checked out your configs and see a few changes that need to be made, however, I have one quick question. Does the local Telco provider of your PSTN line require you to dial a 9 to make calls?
By putting a comma after a digit to your dial plan, the SPA devices can generate an "outside line tone" for you. However, when you utilize this option, the device is going to send the 9, along with the rest of the numbers that you dialed, to the Telco provider. In an office environment that's using a SPA9000, the 9 gets "stripped" at the trunk before it's sent out. On a side note, I noticed that your PSTN port is set to 5070, so I adjusted it below.
Here are a few dial plans you can test out on the SPA921:
If the PSTN doesn't require 9:
(1234<:@123.123.123.12>|1xxxxxxxxxx<:@123.123.123.12:5070>)
If the PSTN does require 9:
(1234<:@123.123.123.12>|9,1xxxxxxxxxx<:@123.123.123.12:5070>)
This one is I haven't tested out in the lab yet, but I'm curious to see if it would work. If it doesn't, let me know.
If the PSTN doesn't require 9, but you would like to utilize the "outside tone" feature:
(1234<:@123.123.123.12>|9,<9:>1xxxxxxxxxx<:@123.123.123.12:5070>)
Hope that helps.

Thanks for the quick reply and the advice. The local telco provider does not require a 9 to dial out. So if we can bypass that feature that would be great. Is there any other necessary changes that need to be made in order to get the VOIP phone to ring when the home phone rings? That is an issue we've been tackling with as well.
Thanks again! :)

No problem. Since the Telco doesn't require a 9 to be dialed, then I would change the dial plan on the SPA921 to the first option:
(1234<:@123.123.123.12>|1xxxxxxxxxx<:@123.123.123.12:5070>)
Referring to your question on having the VoIP phone to ring when the house number is called, you won't be able to do that. The Telco would have to modify their call routing to include the unregistered phone. Since the SPA3102 has 1 FXS (analog phone) and 1 FXO port (PSTN), you can have the VoIP line ring by setting the "Ring thru to line 1" option to yes.

For some strange reason I still am unable to dial out on the VOIP phone. I changed the dialing plan, so that a 9 does not need to be pressed. However, once I enter a number to be dialed I immediately get a fast busy.
Any suggestions or ideas? :(

As long as the SPA3102 has an RJ-11 line running from the FXO port to the wall jack, it should dial out with no problems. Would it be alright if I tested this in our lab?
On a side note, I'm unable to ping the SPA3102 at the address of 123.123.123.12.

Ah, sorry for the confusion, I wasn't sure if I should put the real IP's on here.
SPA921 phone - xxx.xxx.14.19
SPA3102 gateway - xxx.xxx.219.14
Thanks again for your help. :)

No prob. I replicated this in the lab. When making a call using the dial plan I supplied, I get a "Forbidden" error on the phone. I checked the configs you posted for the SPA3102 and saw where the Forbidden error was coming from. Under the PSTN Line tab there's a place you can add up to 8 dial plans. By default they are usually (xx.) The first DP has (5678<:@216.190.15.1>). So when I make a test call, I'm restricted to that particular DP. If you change it back to (xx.), it'll work. Making this change will not prevent you from calling 5678. That's properly setup on the Line 1 tab.
Let me know if that resolves the problem.
Thanks,
Derek
PS - Edit your last entry and remove the IP addresses now. :-)

Sweet! Hallelujah! I can now dial out of the SPA921 to an outside line. You're a saviour.
The final problem I'm facing now is that calls to the house are not ringing the SPA921 VOIP phone. PSTN Ring Thru Line 1 is set for "yes", but for some reason it's not ringing thru.
08-05-2009 05:10 PM
Awesome! :-)
You would like for everyone that calls the PSTN line connected to the SPA3102 to ring the SPA921 as well, correct?
If so, I did some experimenting in the lab and got this to work. :-D
On the SPA3102 - PSTN Line TAB
Type this dial plan in the "Dial Plan 2" field:
(S0<:5678@INSERT_IP_ADDRESS_OF_921_HERE>)
Enable the PSTN-to-VoIP Gateway (if it isn't already on)
PSTN Ringthru Line 1 set to "No"
Set PSTN CID for VoIP CID to "Yes"
PSTN Caller Default DP - 2
FXO Timer Valves
PSTN Answer Delay - 0
Let me know if that works for you.
