I can't hang out Cisco IP phone 7961

[deadlock2011]

Hi supporters, when I start calling from my Cisco IP phone to a dialog phone, I try to hang out to stop the call but I can't. I was press end call but dialog phone still ring, it's none stop. My Cisco IP phone's firmware is SCCP and my account registering on ISP is SIP account. I don't know why I can't hang out when calling to a dialog phone while I can hang out from Cisco IP phone and Cisco IP phone in LAN.

I don't know why I can hang out? What should I do to hangout when I press "end call". Let me know if you want anything else. Please help me resolve this problem, thank you very much!

What is a 'dialog phone' ?

[deadlock2011]

Hi, example my Cisco IP phone called "A" (inbound), calling to another phone called "B" (outbound).

When I press "End call" from A to hang out, B not end call, it's still ringing. I don't know why that? My Cisco IP phone use firmware SCCP 8.3 and use VoIP service of ISP ( internet service provider ) via a SIP account. I was create a number in Cisco IP phone and configure something to call outbound. But I can't hang out when I calling? I hope you can resolve my problem, thank for your answer!

You can check "debug ccsip message" with "term mon" when making a call.

You see that when you hang up, CME sends CANCEL, or BYE.

Then if the called phone stil rings, that is a problem with your SIP provider, and you cannot do nothing about it.

Cisco phone to cisco phones working properly, is because they use the same protocol; SCCP.  when making an external call, you are using both SCCP and SIP signalling, your problem will most likely be with the SIP signalling between you and your provider. I am guessing it has to do with SIP early offer.

send us full config and debug ccsip, when making a test call

As mentioned above, when you hang up CME sends SIP CANCEL, so the problem is with your SIP provider, complain to them, you cannot do anything about it.
