<br>
I have this in my dialplan :<br>
<br>
exten => s,n,Set(vgLabel=vg(${number}+1))<br>
exten => s,n,GoTo(${vgLabel})<br>
<br>
But in stead of vgLabel becoming the SUM of 2 numbers, it is just a string :<br>
<br>
[Nov 3 16:17:27] -- Executing [s@macro-f:43]
Set("SIP/test-00000002", "vgLabel=vg(1+1)") in new stack<br>
[Nov 3 16:17:27] -- Executing [s@macro-f:44]
Goto("SIP/test-00000002", "vg(1+1)") in new stack<br>
[Nov 3 16:17:27] NOTICE[23048]: pbx.c:3744 pbx_extension_helper: No such
label 'vg(1+1)' in extension 's' in context 'macro-f'<br>
[Nov 3 16:17:27] WARNING[23048]: pbx.c:9625 pbx_parseable_goto: Priority
'vg(1+1)' must be a number > 0, or valid label<br>
<br>
<br>
How to overcome this ?!<br>
