Hello, I have an ISDN-30 connection and a Digium TE-121 with VPMADT032 echo cancellation. Every 30-60 minutes I experience PRI dropping. @@@ /etc/zaptel.conf: loadzone=dk defaultzone=dk span=2,1,0,ccs,hdb3,crc4 bchan=32-46 dchan=47 bchan=48-62 @@@ @@@ /etc/asterisk/zapata.conf [channels] switchtype=euroisdn usecallerid=yes group=2 signalling=pri_cpe context=incoming channel => 32-46 channel => 48-62 @@@ With PRI debug turned out I get this output: @@@ q931.c:2755 q931_restart: call 32768 on channel 1 enters state 62 (Restart)> Protocol Discriminator: Q.931 (8) len=13 > Call Ref: len= 2 (reference 0/0x0) (Originator) > Message type: RESTART (70) > [18 03 a9 83 81] > Channel ID (len= 5) [ Ext: 1 IntID: Implicit PRI Spare: 0 Exclusive Dchan: 0 > ChanSel: Reserved > Ext: 1 Coding: 0 Number Specified Channel Type: 3 > Ext: 1 Channel: 1 ] > [79 01 80] > Restart Indentifier (len= 3) [ Ext: 1 Spare: 0 Resetting Indicated Channel (0) ]< Protocol Discriminator: Q.931 (8) len=13 < Call Ref: len= 2 (reference 0/0x0) (Terminator) < Message type: RESTART ACKNOWLEDGE (78) < [18 03 a1 83 81] < Channel ID (len= 5) [ Ext: 1 IntID: Implicit PRI Spare: 0 Preferred Dchan: 0 < ChanSel: Reserved < Ext: 1 Coding: 0 Number Specified Channel Type: 3 < Ext: 1 Channel: 1 ] < [79 01 80] < Restart Indentifier (len= 3) [ Ext: 1 Spare: 0 Resetting Indicated Channel (0) ] -- Processing IE 24 (cs0, Channel Identification) -- Processing IE 121 (cs0, Restart Indicator) q931.c:3581 q931_receive: call 32768 on channel 1 enters state 0 (Null) -- B-channel 0/1 successfully restarted on span 2 @@@ For each and every channel (see full output at http://sprunge.us/fUEd ) I have had two technicians from my telco out here and measuring.

Is your PRI dropping calls, or are the unused B channels resetting? What is your resetinterval in the /etc/asterisk/zapata.conf?

It was just B channels resetting. Yesterday I had them dropping, and thus I just hurried sending a message today, without noticing that they were just resetting. 2009/3/24 Brandon B. <brandon at brellsystems.com>:> Is your PRI dropping calls, or are the unused B channels resetting?
