Setting up an Obi 202 + Obiline in the UK (Draft)
Mouse:
Thanks I have set 400 Ring Delay and disconnect tone of 400@-30,400@-30; 2(3/0/1+2)
Working OK so far, will report back later.
I have also found on my long line that a line impedance of 320 + 1050||230 seem to help the echo.
Just to note that in general when experimenting with different impedances, you may have to increase the TX or RX gain, or DTMF may not be recognised. I think some impedances have a higher power loss rate at DTF frequencies than others.
(There seems to be little margin in the TX gain of 0db!)
Mouse:
Comparing echo on 110 and 202 I happened to notice that the latest 110 file did not set phone port ringer parameters. It did set ring delay though.
Could be there's a problem with the restore function......
110 is significantly better than 202 re echo BTW on my line.
202 still working OK with new disconnect settings .....
Mouse:
Applied disconnect tone settings to 110: 400@-30,400@-30; 2(3/0/1+2)
Mouse:
Now have both 110 and 202 working simultaneously ;D
Both have outboud SIP and PSTN
Both receiving PSTN calls, though probably only one receiving SIP calls (firewall port forward rule)
Mouse:
I am just wondering whether the best way to solve the PSTN echo is to use the 220+110 and send back the obiline.
I'm guessing I can fork our main phone system to both Obis.
Then on the 110 I could set the line socket to send through to PH as usual. Phone socket could default to a SIP service, as I am happy to use SIP outbound always.
On the 202, there would be no line connection, it could use any SIP outbound and receive inbound SIP.
More elegantly I could use the 202 as the front end for all outbounds, referring using Obitalk requests for outbound PSTN connections to a 110 running in the 202s network. Inbound SIP could then go to either depending on the SIP service (using server IP-based PF rules). Inbound PSTN would go to the 110. (Port forward rules would be fun ;D)
What do you think?
