* Updates to Yealink codec provisioning
Changed codecs to use variables set in default settings.
* Added basic provisioning for swissvoice cp2502 and cp2505g
Codec handling set in default settings.
Need to still work on directory and funtion keys.
* Update app_config.php
* Mitel phones require the exact model in the template. A 5320 and 5320e phones take an identical template. The "e" model has a gigabit ethernet port.
* 1. Added variable {$domain_name} in a few places that need it.
2. Set the NTP server to use dns name instead of IP address.
3. Set dns for NTP to use pool address (0.pool.ntp.org)
4. Removed Admin account to set back to defaults. Will look at setting that as variable.
5. Hardcoded user account password to be more simple. Will look at setting that as a variable.
6. Set host_ip and video_ip to be {$domain_name} as these were pointed to an AT&T old dns server
7. Set hostname of phone to be SIP ID
8. Remove hardcoded IP for NTP and added the DNS pool.
9. Removed boot version and image version from template as wasn't in other provision systems.
* 1. Set admin password to use provisioning variable.
2. Set user password to use provisioning variable.
Setting ignore_early_media=true has a better chance of success for T38 fax transmissions.
Setting this as a fax variable in default settings is enough for most cases where a successful transmission occurs on the first attempt. However if fax retries are needed this variable was ignored until now.
This change ensures that IF the user sets ignore_early_media=true as a default fax setting it will also be used for fax retry scenarios when T38 is enabled. If ignore_early_media is not set to true then the changes here are ignored thus minimizing risk.
