Hi All,
As mentioned below, were are trying to develop charging module for kamailio-ims
(using ims_dialog).
Unfortunately you have removed both 
                event_route[dialog:start]
                event_route{dialog:end]
from the ims_dialog module.

Also observed you have  currently not provided facility for exporting ims_dialog  pseudo-variables

https://www.kamailio.org/docs/modules/stable/modules/ims_dialog.html#idp45013844

We are unable to proceed further and stuckup badly.

Kindly suggest a way to get call times.

Kindly answer  the mail as soon as possible. We are waiting for your reply.

Regard,
Prasannakumar.

We need events
    event_route[dialog:start]
    event_route[dialog:end]
for detecting call begin and call end.

We have to use ims_dialog module for IMS implementation. But observed that ims_dialog module
doesnt have the above said events [dialog:start and end].

How do we implement those events using ims_dialog. Is there any other way out.

Kindly suggest.

Thanks,
