> This functionality is disabled by default, but when enabled it will tell Asterisk to  ignore the crypto lifetime key component if one is specified.  Using this option I was able to successfully make TLS/SRTP calls to the Sangoma Express Gateway.  This patch would not be necessary if the Sangoma Express Gateway provided an option to disable the lifetime specification; but it appears that it does not.
> Without this patch, any SRTP offers that specify the optional lifetime key component will fail.
> This patch was also tested by Ryan Mayer (mantis user: 'hidden').  Thanks Ryan!
