#### Description <!-- Describe your changes in detail --> I was looking for a solution to set a dedicated From URI in OPTIONS requests to a specific dispatcher target.

ds_ping_from ( https://www.kamailio.org/docs/modules/devel/modules/dispatcher.html#dispatch...) applies globally, while I needed the granularity of a single target.

I can just add an attribute to the others, e.g. instead of

``` 1 sip:127.0.0.1:7070 http://127.0.0.1:7070 0 1 ```

something like:

``` 1 sip:127.0.0.1:7070 http://127.0.0.1:7070 0 1 ping_from=sip.custom.com ```

When the ping_from attribute is not specified, the general ds_ping_from applies and is used.

This would save me from a solution like intercepting the outgoing OPTIONS and manipulating the From header. You can view, comment on, or merge this pull request online at:
