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:

    -- AGI Script Executing Application: (Set) Options:

    -- AGI Script Executing Application: (Dial) Options:

    -- 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",

You're right it seems to be string length related. With shorter names
(SIP/x1&SIP/x2...) I can watch about 9-10 devices. It looks like the string
is limited to about 80 chars. I hope it's not intended to be like that.
