[OpenSIPS-Users] opensips 2.1 call_center queue position

Hi Jonathan,
I was not able to test it with a real queue, so let me know if it really
does the job (in terms of reporting the real position in the queue).
Some questions:
1) currently I add that value only when sending to the queue / MOH - do
you foresee any need to be added for other announcements like for welcome ?
2) will it be useful to add the ETW (estimate time to wait) ? is it useful ?
