According to pjsip specification, media_encryption parameter should have
value of:
no   - res_pjsip will offer no encryption and allow no encryption to be setup.
sdes - res_pjsip will offer standard SRTP setup via in-SDP keys.
       Encrypted SIP transport should be used in conjunction with this option
       to prevent exposure of media encryption keys.
dtls - res_pjsip will offer DTLS-SRTP setup.

We support at the moment only sdes media encryption hence translate
encryption=0 from uci config to media_encryption=no in pjsip config
and encryption=1 to media_encryption=sdes.

Issues:
 - kill -p option not working
 - pidof not get the correct pid
 - killall asterisk kill the script itself as well

The original value was "yes" or "no". config_asterisk.sh is also updated for the adaptation.

Outgoing anonymous call is handled in chan_brcm.c based on the 'anonymouscallenable' value from
chan_telephony.conf. Additional handling it by the dialplan in extension.conf is not needed and
introduced issues.

Release an unanswered incoming call if the user rejects it

/etc/config/asterisk is the only UCI config file that needs to be kept during a firmware upgrading
for asterisk. /etc/asterisk contains config templates which are used to generate the actual
asterisk config files located in /var/etc/asterisk during running time.

But some config templates were wrongly kept /lib/upgrade/keep.d/ which prevents the old config
templates from being overwritten by a firmware upgrading.

Fix a bug that two call progress tones are being played simultaneously

[22.03] asterisk: add --without-libxslt to configure

Since upstream commit b40c4d59b1dd803cad79060fb5b5a48d249ba578
"--disable-xmldoc" does no longer prevent the linking to libxslt, if
available. If that's the case one is greeted with the following error:

Package asterisk is missing dependencies for the following libraries:
libxslt.so.1

This commit explicitly disables the use of libxslt, to avoid the
dependency.
