Changed SIP NOTIFY Event header for Grandstream phones to allow provisioning with out requiring a reboot of the device. Based on communication with a Grandstream support rep. Tested on Grandstream GXP2130 and GXP2160 models.
This scenario was broken:
A ring group member forwards their phone to a destination. The destination is an external number and the outbound route had a toll_allow condition.
This error would be generated: [ERR] switch_cpp.cpp:1376 [route_to_bridge] Unsupportded condition: ${toll_allow}
This PR will get the toll_allow values from the RG member that is forwarding their phone. Then it will pass it to 'route_to_bridge.lua'.
* Add. Use `route_to_bridge` module to build routes fro ring groups.
This commit has several improvements
1. Select only needed fields. (do not select quite big XML text strings)
2. Filter routes also by context name
3. Filter dialplans also by hostname
4. Handle conditions based not only `destination_number`
5. Handle `break` and `continue` attributes for extensions
6. Escape vars inside dial-string
7. Add log messages similar as FS dialplan do
* Add. `route_to_bridge` set inline vars so it possible use then in next conditions.
Add. `route_to_bridge` can execute basic api commands from allowed lists.
`route_to_bridge` expand all known vars. If var is unknown then it pass as is.
Fix. `export nolocal:` action.
* Fix. Short variable names
* Add. some comments
* Fix. Do not try execute empty string
This produce error messages `[ERR] switch_cpp.cpp:759 No application specified`
* Fix. Export nolocal values.
