Question Regarding OBI as a analogue bridge
MBrown:
Hello,
I am looking for a way to extend two analogue lines over a ip network, i am thinking i can do it with some obi's but would like to confirm before i tell my friend to buy some.
There is a small office that is only connected to the main building by WIFI they need a couple of extensions in the office off the main phone system. The Phone system only supports analogue phones. My idea was to have two obi's at the phone system side (side a) and cable two extensions into the OBI110 on its PSTN port, have one OBI220 in the small remote office with two analogue phones.
My questions are:
1.
Can i set the OBI up in such a way the when an inbound call arrives on the OBI PSTN port (side a) it will ring a designated analogue phone the other side of the bridge (side b)
2.
Can i set the analogue phone to "hotline" when i pick up the handset on side b I am presented with the analogue dial tone from the pstn line on side a.
Or failing that just dial a short access code to route to the side a pstn line.
I am thinking i will need two OBI110 for side a to provide the two PSTN ports and one OBI 202 for side b to provide the two analogue phone ports. Can some one please confirm if this will work?
Many thanks advance for any help you can provide.
Regards
Marc

Yes, it can be done as you describe with a hotline or code to get dial tone on a PSTN line and routing inbound calls. I think a better way is to get dial tone from the OBi202 and then route any outbound call to one of the OBi110s. This way you wouldn't have to wait to get dial tone from the OBi110. You would also be able to use a phone book on the analog phone's handset or pre-dial a number and then press send.

Thanks azrobert
I have ordered a 202 and 110, i will post here how i get on.

Below is my recommended configuration.
I did not test any of this and hopefully I didn't make any mistakes.
OBi202
Service Providers -> ITSP Profile A SIP -> ProxyServer: 127.0.0.1
Service Providers -> ITSP Profile A General -> DigitMap:
(1xxxxxxxxxx|<1>[2-9]xxxxxxxxx|011xx.|0|XX.S3)
Voice Services -> SP1 Service -> AuthUserName: OBi202
Voice Services -> SP1 Service -> X_RegisterEnable: unchecked
Voice Services -> SP1 Service -> X_InboundCallRoute:
{OBi110b:ph2},{ph}
Physical Interfaces -> Phone1 Port -> OutboundCallRoute:
{(<#:>):ph2},{(XX.):sp1($1@aa.aa.aa.aa:5060)}
Physical Interfaces -> Phone2 Port -> OutboundCallRoute:
{(<#:>):ph},{(XX.):sp1($1@bb.bb.bb.bb:5060)}
OBi110a
Service Providers -> ITSP Profile A SIP -> ProxyServer: cc.cc.cc.cc
Service Providers -> ITSP Profile A SIP -> X_SpoofCallerID: Checked
Voice Services -> SP1 Service -> AuthUserName: OBi110a
Voice Services -> SP1 Service -> X_RegisterEnable: unchecked
Voice Services -> SP1 Service -> X_InboundCallRoute:
{>(<0:>):li},{li}
Physical Interfaces -> Line Port -> InboundCallRoute: sp1(0)
OBi110b
Service Providers -> ITSP Profile A SIP -> ProxyServer: cc.cc.cc.cc
Service Providers -> ITSP Profile A SIP -> X_SpoofCallerID: Checked
Voice Services -> SP1 Service -> AuthUserName: OBi110b
Voice Services -> SP1 Service -> X_RegisterEnable: unchecked
Voice Services -> SP1 Service -> X_InboundCallRoute:
{>(<0:>):li},{li}
Physical Interfaces -> Line Port -> InboundCallRoute: sp1(0)
aa.aa.aa.aa is the IP address of OBi110a
bb.bb.bb.bb is the IP address of OBi110b
cc.cc.cc.cc is the IP address of OBi202
OBi202 Phone1 port will route outbound calls to OBi110a
OBi202 Phone2 port will route outbound calls to OBi110b
Dial "0" to get dial tone on the respective OBi110 PSTN line
Any other number will be routed out the PSTN line.
Inbound calls on OBi110a will be routed to OBi202 Phone1
Inbound calls on OBi110b will be routed to OBi202 Phone2
Dial # on either OBi202 phone port to ring other phone port
