[Asterisk-Users] X100P problems / UK Supplier of TDM400P FXO cards
This didn't seem to appear on the list, so I'll try again. Apologies if this is a repeat post. Hi everyone, I wonder if anyone (esp. UK-based) could help us with the following (skip to the last paragraph if you don't want the detail!):- We have been trying to get an Asterisk-based VoIP server set up for our (small) office. We have two incoming analogue lines and two phones - one analogue and one multi-handset DECT. We also want to be able to send/receive calls over SIP to X-Lite. We have got a machine with Asterisk installed and SIP <-> SIP calls are working fine. However, we need to be able to access the two incoming analogue lines. We bought two X100P s and two GrandStream HandyTone 286s. Calls from the two POTS phones seem to be fine to SIP phones, but calls between the outside world and either the POTS phones or SIP phones are terrible. Initially we had dreadful echo, we have used 128 taps of echo cancellation and the echo is somewhat better (although it is still dreadful for the first 10-20s of the call). However, we now get quite a lot of "breaking up" while the person on the SIP phone / our analogue phone is talking. I believe the cause of this is the X100P - in particular, the impedance. As far as I can tell, in the UK, the lines are Zcomplex (2) = 230 nF // 1050 ohms + 320 ohms. The X100P seems to only be able to produce the US impedance = 600 ohms. As far as I can find out, the Digium TDM400P with FXO modules would not have this problem, as it has a software-adjustable impedance. However, I have not been able to find a supplier in the UK of the FXO modules for the TDM400P. So, this is where you might be able to help! * Have you used X100P cards in the UK successfully? * Do you know a supplier of TDM400P cards in the UK?

[Asterisk-Users] X100P problems / UK Supplier of TDM400P FXO cards
http://www.telappliant.com/ bought a lot of kit from them and would recommend them. Support line is very helpful (until you take the pee like we did :-P ). I couldn't get the X100P working even with the latest CVS build and using the apparent fix: Cidsignalling=v23 Cidstart=polarity Usecallerid=yes Try Googling >> site:lists.digium.com uk caller id That will show you the many many threads about this. If you do get any joy with I would be interested to know incase there is something I did wrong.

http://www.voiptalk.org/products/Telephony+Cards/Handset+Interface+%28FX S%29+Cards?sess=982ccc6b6557552f5f60be690fde5319 TDM400P ^^^^^ As it only has FXS ports and no FXO's I guess it doesn't need to be approved as the FXS side isn't plugged directly into the PSTN ?????
