[asterisk-users] hangup problem on T1 span
Hello all, I'm trying to solve a problem on a T1 span setup wherein calls are apparently not hanging up properly. The system in question is using a Xorcom Astribank with 1 full and 1 partial T1 span, and running Asterisk 1.4.36. The symptom is that when a call hangs up on a DAHDI channel (according to Asterisk), and another outgoing call tries to open a new channel on the same line as the hung-up call within approximately a minute of the hangup, the new call gets a congestion notice ("all circuits busy") from asterisk. After about a minute passes after the hangup, the line becomes available again. So it seems like the channels are not hanging up when Asterisk tells them to, and Asterisk doesn't know it. I suspected a signaling issue, and this appeared confirmed when I discovered that the signalling was set in chan_dahdi.conf as "fxs_ks" (this installation had been converted from analog lines by another company; I guess that was an oversight?). So I changed it to pri_cpe, as my reading of the docs indicated was proper. After this change and restarting everything, though, the symptoms persist. So I figure that either my reading of the docs is wrong (and therefore pri_cpe is not the right signaling) OR something totally unrelated is going on. Can someone please clue me in here? I am a bit at a loss. Let me know if you need further information about the system/environment.
