spa112 connected to spa3102???

Hello. I'm attempting to configure a spa112 to connect to a spa3102. The spa3102 is located at POINT "A", and has a pots line connected to it's fxo port. The spa112 is located at POINT "B", but on the same LAN. I need the pots line to ring to a fax machine at POINT "B" which is connected to the spa112. Also, we'd like to access the pots line at POINT "B" to send faxes as well. Currently niether is working. When I go off-hook on the spa112, the spa3102 shows it's answering but nothing else happens. Any help would be greatly aprreciated. Thanks.

spa112 connected to spa3102???

I GOT IT!!! I used the following settings but if you want to see from HW, the original poster, here's the link:

http://homecommunity.cisco.com/t5/VoIP-Adapters/Connect-back-to-back-2-SPA-3102/td-p/188833.

Just be sure to use the Internet port on the spa3102 and not the Ethernet port which was my mistake. and also add the default dial plan to dial plan #1 in the spa3102

Configure As Follows:

On the SPA3102 attached to the PSTN line.

PSTN Line Tab

Line Enable: YES

NAT Mapping Enable: yes or no depending on the router used

NAT Keep Alive Enable: yes or no depending on the router used

Register: No

Make Call Without Reg: Yes

Ans Call Without Reg: Yes

UserID: spaone

VoIP-To-PSTN Gateway Enable: yes

VoIP Caller Auth Method: none

VoIP Default DP: 2

VoIP Caller Default DP: none

none will give you the actual PSTN dial tone when the VoIP-to-PSTN gateway answers the call

PSTN-To-VoIP Gateway Enable: yes

PSTN Caller Auth Method: none

PSTN Ring Thru Line 1: no

PSTN Caller Default DP: 2

Dial Plan 2: (S0<:spatwo@ipaddress: 5060> )

The dial plan will automatically dial the distant SPA112 Line 1 when the PSTN-to-VoIP gateway answers the call

Where spatwo is the userid on the Line1 tab of the distant SPA112 (spatwo)

Where ipaddress is the ip address of the distant SPA112

Where 5060 is the sip port number of the Line 1 tab on the distant SPA112

VoIP Answer Delay: 0

PSTN Answer Delay: 2

Where 2 seconds is long enough to receive an incoming caller id on the pstn line (if you care about it)

Line-In-Use Voltage: 30

Where 30 is about half way between the on-hook and off-hook voltage of your pstn line (polarity disregarded)

Line 1 Tab

Enable IP Dialing: YES

On the Distant SPA112 Line 1 tab

Line Enable: Yes

NAT Mapping Enable: yes or no depending on your router

NAT Keep Alive Enable: yes or no depending on your router

Register: No

Make Call Without Reg: Yes

Ans Call Without Reg: Yes

UserID: spatwo

DialPlan: (S0<:spaone@ipaddress:5061> )

Where spaone is the useid on the pstn line tab of the SPA3102 attached to the pstn line

Where ipaddress is the ipaddress of the SPA3102 attached to the pstn line

Where 5061 is the sip port number on the pstn line tab on the SPA3102 attached to the pstn line

Enable IP Dialing: YES

Note: Depending on your network you may or may not have to have NAT Mapping Enable. If you do have NAT Mapping Enable you may also need to configure a STUN server depending on the router that you are using.

If the two ip addresses are not on the same local network you will need to forward the sip port in the router to the SPA3102 and you will need to use the external ip address.
