[asterisk-users] hex b1 in CallerID sent by Asterisk On PRI

[Bob Pierce]

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.
