> Currently, Asterisk reports the pjproject version in any STUN packets it sends in the form of a SOFTWARE attribute, for example "pjnath-2.10.0". This may not be desirable in a production environment for security reasons.
> In `pj_stun_config_init()`, the software name is initialized to PJNATH_STUN_SOFTWARE_NAME but this can be overriden, or even set to an empty string to not send any SOFTWARE attribute at all.
> I'd be happy to provide a patch, but would appreciate some guidance: do we want to make this configurable, or would removing the SOFTWARE attribute be acceptable?
