As a further update to this, I've noticed the following in q931.c at
about line 1236:
static FUNC_SEND(transmit_display)
{
int i;
if ((pri->switchtype == PRI_SWITCH_QSIG) ||
((pri->switchtype == PRI_SWITCH_EUROISDN_E1) && (pri->localtype ==
PRI_CPE)) ||
!call->callername[0])
return 0;
i = 0;
if(pri->switchtype != PRI_SWITCH_EUROISDN_E1) {
ie->data[0] = 0xb1;
++i;
}
memcpy(ie->data + i, call->callername, strlen(call->callername));
return 2 + i + strlen(call->callername);
}
So, I think this is where the b1 is being added.
My question then is, what is the significance of this character?
What's the best way to try sending caller name without this character?
Should I just try changing my switchtype to euroisdn at both sides of
the link?
Bob

As an update to this, I noticed the following lines in libpri.h near line 236: /* Network Specific Facilities (AT&T) */ #define PRI_NSF_NONE -1 #define PRI_NSF_SID_PREFERRED 0xB1 #define PRI_NSF_ANI_PREFERRED 0xB2 So, I've tried specifying nsf=none in zapata.conf, but we still see the b1 preceding the caller name in the pri trace. However, I only did a 'reload chan_zap.so' since this is a production system. Should that have changed the nsf settings for this span? My current zapata.conf is pasted below if that helps...

[asterisk-users] hex b1 in CallerID sent by Asterisk On PRI
I'm trying to send CallerID info to a MetaSwitch system over a PRI. The MetaSwitch gets the info exactly as it is sent by Asterisk, but I think it might be having trouble with the Hexadecimal b1 that is being sent just before the first character of the CallerID Name. Does anyone know what the significance is of the b1 being sent here? Or, is there a way to make Asterisk not send the b1 character as a test? I've pasted a portion of the PRI debug trace below. Thanks for your help.
