Hello everyone,

While programming some parts of my asterisk dialplan, I've noticed thant in some cases, all GoTo aplications fail jumping into certain labels.

When I set a label starting with a number (like "4secs"), The GoTo statement jumps to priority number 4 instead of jumping into priority "4secs".

He're you have the dialplan explained above:

[test]
exten => _63XX,1,NoOP(Dialed ${EXTEN})
exten => _63XX,n,GotoIf($["${EXTEN}"= "6358"]?4secs)
exten => _63XX,n,Wait(1)
exten => _63XX,n,Dial(SIP/${EXTEN:2},10)
exten => _63XX,n(4secs),Dial(SIP/58,4)
exten => _63XX,n,Hangup

And the execution tests:

-- Executing [6358 at test:1] NoOp("SIP/59-0001426c", "Dialed 6358") in new stack
-- Executing [6358 at test:2] GotoIf("SIP/59-0001426c", "1?4secs") in new stack
-- Goto (test,6358,4)
-- Executing [6358 at test:4] Dial("SIP/59-0001426c", "SIP/58|10") in new stack
-- Called 58
-- SIP/58-0001426d is ringing
== Spawn extension (test, 6358, 4) exited non-zero on 'SIP/59-0001426c'

After some research, I found the problem in the code files:

FILE:
main/pbx.c

FUNCTION:
static int pbx_parseable_goto(struct ast_channel *chan, const char *goto_string, int async)

LINE:
if (sscanf(pri, "%30d", &ipri) != 1) {   

In this Statement, if we have som digits at the start of a label. The return of sscanf is equal to 1, and We fail for labels like (4secs)

Thanks for your support!
