Hi, Following the *extremely* helpful assistance of Darren Storer I did establish that the NTL line I currently have is ISDN 85 (partial ETSI) whereas Asterisk and the E100P want *full* ETSI (ISDN 110). Not that NTL even understood what it was I was trying to achieve and were initially very confused at the difference between ISDN 85 and ISDN 110, they just kept repeating that their line was Q.931 and therefore should be fine - certainly not the case! They got there in the end though :)
I did hit a brick wall with NTL on upgrading the line though, the equipment delivering the line to my premises is not up to the job and needs upgrading/replacing by NTL, this has meant it's all had to go off to their finance department for approval etc. etc. Basically I've got mired up in NTL red tape :( You may be luckier in that the equipment used to deliver your line has been upgraded over the last few years to cope with ISDN 110, you'll need to speak with your NTL account manager to find this out. I've been speaking with Darren recently and there *may* be a chance that ISDN 85 support could be coded into the drivers for *, but even if this were to happen it's a way off. If NTL can't upgrade your current line to ISDN 110 and you can't wait for any possible ISDN 85 support in * then your only other option is to look at changing teleco. For me it's not all doom and gloom as the nice people at BT have been able to put a *very* attractive proposal together to persuade me to switch from NTL and provide me with a pucker ETSI line in the process - so hopefully all's well that ends well!

I have to replace this phone system shortly and I've been trying to get a * system working for some weeks now. I have configured the dial plan (which works) and all my SIP extensions (which all work) along with voice mail etc. etc. - all this works perfectly as an internal PBX. My problem comes when I try to connect it to my ISDN line." Thread: http://lists.digium.com/pipermail/asterisk-users/2004-April/044169.html I have exactly the same hardware, telephone company, setup and have exactly the same problem. Im in Lincoln and Im running asterisk version: Asterisk CVS-03/09/04-13:55:16 on a dual PIII500 Linux machine. I have no physical alarm lights, my E100P is working, zttool is reporting no alarms but everytime ntl try to bring up the line I get the same error as you: May 11 14:12:06 WARNING[1192491824]: Detected alarm on channel 1: Red Alarm May 11 14:12:06 WARNING[1192491824]: Unable to disable echo cancellation on channel 1 Etc... Etc.. Etc... For all my 10 channels. Did you managed to solve this by asking ntl to deliver ISDN 110 or was is something else? I hope you receive this because Im getting a bit desperate :( Thanks Darren Darren Round B.Sc.(HONS) MANAGING DIRECTOR Advanced I.T.
