[asterisk-users] Setting outbound PRI Callerid with Asterisk 10.0.0-beta2

[asterisk users]

Hello all,

I'm having trouble setting the callerid name and number independently
with the following configuration:

Asterisk 10.0.0-beta2
DAHDI Version: 2.5.0 Echo Canceller: HWEC, MG2
libpri version: 1.4.12
Allstream PRI 23+D / dms100

Test cases:

(1) Using the form:
    same => n,Set(CALLERID(all)="AB&CD COMPANY" <5191112222>)
    same => n,Dial(Dahdi/G1/5193334444)
both the caller ID and name are passed correctly to the called party

(2) However, if we try to set the number and name separately
  same => n,Set(CALLERID(name)="AB&CD COMPANY")
  same => n,Set(CALLERID(number)=5191112222)
  same => n,Dial(Dahdi/G1/5193334444)
then with some called numbers, we get a congestion message ("All
circuits are busy") unless the first CALLERID(name) line is commented
out.
With other numbers the call completes, but the received callerid shows
as: "CALLERID(all): "\" <5191112222>"

Is there some subtle difference between these two methods, or would
anyone have some experience with this?

Thanks for any comments, and Happy Friday!
