Summary:                    [patch] Deadlock In chan_sip (conlock /
cb_extensionstate
Description: 

There is a deadlock in processing state changes it would appear conlock
should be locked when calling cb_extensionstate from chan_sip.c ...

have a patch ill be loading up in a follow up.

this was a problem in 1.4 that i hacked to death to make it go away this
patch seems to make more sense.

NB we have only now moved from 1.4.36 [with backports] to 1.6.2.16.1 this
problem affects sites with higher call volume and reliance on BLF
[Snom/Polycom] and may be triggered on a sip/system reload
