This happens when the provider sends a message waiting indication down the line, it's interpreted as a ring voltage and generates 2 rings, you're about the tenth person that's had this issue, not always after a call with the others but I'd wager that's what it is or similar

Hai amriddle01,

Thank you so much, its working if i disable the Caller ID, FYI. Any solutions for this?

Just for your information,

I have disabled the Disconnect clear and busy tone detection also, then its working fine. I think i was getting wrong signal from Network to release the trunk. After this modification, trunk will not release automatically but disconnecting from the user side manually.
