<div>So another quick look... when a sucessful call comes in it goes to DS1 Identifier 0... the Asterisk CLI shows the following:</div>
<div> </div>
<div> -- Accepting call from '727403XXXX' to '890' on channel 0/11, span 2</div>
<div> </div>
<div>Is there a way to get the other span (span 3) to become channel 1/xx? So when a call comes in asking for DS1 Identifier 1 I see the following:</div>
<div> </div>
<div> -- Accepting call from '727403XXXX' to '890' on channel 1/12, span 3</div>

<div>Hey all!</div>
<div> </div>
<div>I've been banging my head against the wall for a while (almost 18 hours today alone) with this one... I migrated our incomming T1's from the Option 11 to our Asterisk box this morning. We have 1 local T1 and 2 long distance T1's. The local T1 went over with out a hitch. The problem is with my 2 long distance T1's. The switch on the other end is a DMS250 I'm told so I set Asterisk to DMS100 and got the timing, framing, etc all set. Well, the D channels came up so thats good. I started getting dropped calls every once in a while. I did a debug on the spans and saw the following:</div>
<div> </div>
<div>PRI Span: 3<br>PRI Span: 3 < Protocol Discriminator: Q.931 (8) len=40<br>PRI Span: 3 < TEI=0 Call Ref: len= 2 (reference 857/0x359) (Sent from originator)<br>PRI Span: 3 < Message Type: SETUP (5)<br>PRI Span: 3 < [04 03 80 90 a2]<br>

<div>The key part is the "<strong>Ext: 1 DS1 Identifier: 0</strong>" part. That's when calls fail. Right now, all calls are coming in on span 3 and want to talk to Identifier 0 (span 2). If a call comes in on span 2 and requests "<strong>Ext: 1 DS1 Identifier: 1</strong>", it fails. I called Verizon and asked them what was going on. Turns out, its configured as a trunk group. The tech mentioned that I need to figure out how to set my identifiers on the group and I should be good to go. I've done a ton of research about chan_dahdi.conf and dahdi-channels.conf and I think the answer is trunk groups.</div>
<div> </div>
<div>I tried configuring a trunkgroup and set the primary dch to 24 and the bdch to 72 and then then spanmap'ed span 2 and 3 into group 1 (e.g. 2,1,0 and 3,1,1) but I don't see anything when I do a "dahdi show channels" or a "pri show spans" or a "pri show channels", not even the channels not in the group. If I delete the trunkgroup, all three commands return all the channels.</div>
<div> </div>
<div>I'm just curious if I'm going down the right path with trunkgroups for this or if there is something else to take care of the DS1 Identifier issue.</div>
<div> </div>

<div>Thanks in advance everyone!</div>
