Richard Mudgett commented on PRI-172:
-------------------------------------

Since you have configured Asterisk to be the CPE/user side of the BRI PTMP line, the Patton SN 4638 must play the role of the network.  Q.931 Section 3.1.14 Table 3-15 Note 4 in regards to the Channel identification IE:
{quote}
NOTE 4 – Mandatory in the network-to-user direction. Included in the user-to-network direction when a
user wants to indicate a channel. If not included, its absence is interpreted as "any channel acceptable".
{quote}

In addition, for BRI lines the CPE side cannot pick a B channel for exclusive use without the possibility of some other device already using it.

You should consider switching the network/user roles of Asterisk and the Patton since the Patton is acting sort of like the user even though it is allocating TEIs.

> My lab setup is:
> Phone1 <---> Asterisk1 <--SIP--> Patton SN 4638 <-- BRI--> Asterisk2 <---> Phone2
> Inside Asterisk2 box is installed an HA8 board with a single 4 BRI module.
> When dialing in from phone1 to phone, no call is established and  Asterisk2 shows:
> ERROR[3819]: chan_dahdi.c:14480 dahdi_pri_error: PRI Span: 1 XXX Missing handling for mandatory IE 24 (cs0, Channel ID) XXX
> When dialing out from phone1 to phone, call is established Asterisk2 shows:
> WARNING[4054][C-00000002]: app_dial.c:1546 wait_for_answer: Unable to write frametype: 2
> I've played such setup hundred times with older versions of Asterisk/Dahdi/Libpri combinations.
> This is the first time I'm observing this and this occurs with version mentioned in Environment.
> I've recorded pri intense debug in a file I can send.
> Before filling this issue, I've googled a bit and found nothing either recent or helpful. Please, apologize if I missed anything.
> I can of course, handle configuration details but I must add I got this issue while preparing/testing to upgrade an 3-4 years old system.
