Incorrect call duration - Outgoing calls

[sanketgroup]

With 200 OK immediately problem is - it starts counting call duration immediately and even call is not picked up at other end, it shows call duration.

Patton are correct in the fact that it is not illegal to send a 183 without SDP and then send a 183 with SDP, it is just that the 3CX software processes like that.

The ideal solution for you is not possible to solve both problems. Let's not forget that with the default Patton settings send the 200 OK immediately, and now we probably know the reason why that is.

Yes, so no ideal solution unfortunately it seems, either the call duration will show up during the Early Media or Early Media is not heard at all, but call duration is correct.

That seems to be the dilemma as we cannot change the behavior on our side to process subsequent 180 or 183 messages and Patton not being able to send the first 183 with SDP when necessary...

Incorrect private IP in SDP

They told it is not always necessary that first 180 or 183 must contain SDP, but 3CX shall able to handle subsequent SDP if not found in first.

Now in your case, the first message that arrives is a 183 message, yes, but it is without SDP. This means that the audio transaction has not yet been established. Right after that, the Patton device sends a second 183 message that does contain SDP, but due to the fact that 3CX software will disregard any subsequent similar messages (explained above), nothing happens.

but now we also know that 3CX will disregard private IP from Provider Settings 8)

I hope someone (patton or 3cx) agress to resolve this.
Both are technology partners and very well integrated with each other.

If 3cx feels it is really patton issue pls ask patton to resolve.

I believe 3cx also can resolve on their side if you want as developer.

This issue is not limited to me only. Must be happening at wide with many users.

Again I request to resolve either from your or pls ask patton.

Thanx

As far as I am aware this isn't on the 'to do' list, however I would suggest you add this as a feature request on the 'Ideas' section of our forum so it can get upvoted by other users as well.
