Suppress ringing for calls looping back to the very mobile phone I am on myself

[frittentheke]

When placing a call via the mobile phone network which then loops back to myself (CSipSimple on my phone) the ringing should be suppressed. I don't see the point of calling myself on the very phone I place the call with. Usually in this case there is some other client registered to the number my CSipSimple client is registered to which is the actual target of the outbound call.
