This sounds like you have it set for T1 somehow? Have you upgraded anything lately? Other than that, a Trend tester will show the problem(s) to you.
BTW - E1's are 32 channel (not 31). It's 30B+2D. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of deeps backup Sent: 13 May 2011 16:57 To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] DAHDI Error I can dial 1-24 channels but not after that.

It is a common issue. I usually put something in my dialplan to retry all calls that receive an unexpected hangup cause to work around the telco seemingly randomly sending back odd hangup causes. You should not retry ALL calls, only ones with unexpected hangup causes. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
