Summary:                    Asterisk can't watch for more than 5 devices on a
single hint
Description: 
Here's the hint in dialplan:
[xyz]
exten =>
__PRS2_010,hint,SIP/xyz010001&SIP/xyz010002&SIP/xyz210001&SIP/xyz110001&SIP/xyz010101
there're currently 5 devices to watch and everything works fine if i make
a call to SIP/xyz010101 (last one):
    -- Executing [101 at xyz:1] Set("SIP/xyz112201-b7304288",
"TIMEOUT(absolute)=10800") in new stack
    -- Channel will hangup at 2008-11-21 22:17:36 UTC.
    -- Executing [101 at xyz:2] AGI("SIP/xyz112201-b7304288",
"agi://pbxtest") in new stack
    -- AGI Script Executing Application: (SetCallerPres) Options:
(allowed_passed_screen)
    -- AGI Script Executing Application: (Set) Options:

    -- AGI Script Executing Application: (Dial) Options:
(SIP/xyz010101|15|)
    -- Called xyz010101
    -- SIP/xyz010101-081f8b58 is ringing

Now I'm adding another device to watch in front of SIP/xyz010101 making it
6th device:
[xyz]
exten =>
__PRS2_010,hint,SIP/xyz010001&SIP/xyz010002&SIP/xyz210001&SIP/xyz110001&SIP/xyz011101&SIP/xyz010101
and do 'dialplan reload'. asterisk takes this configurion without a word
of complain, but now the state of SIP/xyz010101 is always Idle:
    -- Executing [101 at xyz:1] Set("SIP/xyz112201-b7304288",

It is intentionally coded that way and it's not likely to be something that
we're going to change in 1.4.  Increasing the substitution buffer may cause
stack issues.  This will, however, be fixed as of the 1.6.2 release.
