Sorry, I intended to post to users, but realized it went to biz
afterward. Long story as to why. I thought it would be silly to post
a retraction too.<br>
<br>
Since you've answered (thanks), I might as well complete the thread. I
am not trying to determine the device type. I am trying to determine
the device identification, like say, "SIP/12345", or whatever. I use
it to associate configurable attributes with physical stations. I
noticed that channel names are comprised of this device ID with five
more characters appended, presumably for uniqueness. My code removes
these last five characters, and it does in fact work as intended in my
application.<br>
<br>
But as I implied, I think it is less than elegant. And it seems that
there ought to be a variable that directly represents the value I want,
but I hadn't found it documented.<br>
<br>
Hence my inquiry.<br>
<br>
Thanks again for your input.<br>

try that list.
Your code doesn't make sense to me, if all your trying to see is what
device type is making the call then this will do:
set(DTYPE=${CHANNEL:0:4}) should give you either SIP/ or ZAP/ for those 2 types.
if you want everyting after the slash ('/') then this will do for</pre>

No, I want everything before the last hyphen, which seems to mean that
I want to omit the last 5 characters.<br>

if you want the above but that device should never contain the hex
value for the SIP calls, so that all you get is the device from
sip.conf and not the -abc3:</pre>

This is closer to what I am seeking.<br>

The above should give you 1324 for a channel that holds SIP/1234-abc3

I strongly suspect that there is a better way.
Eh?
