Hi Ayodeji, I just tried

barry florence · ‎01-14-2015

call manager 10.5.1.10000-7

(2N Helios IP ) door system(2042)-> cucm->DX650(3513)

Time stamp:16:23:27

Hi

when call initiated from door system to user (DX650), it rings, once answered on the phone it disconnects the call and gives fast busy tone instead of connecting the call. Same calls work in jabber and also in sccp phones. I have attached the call manager trace, please help on this.

Thanks

Barry

Your call is being cut down with normal call clearing. Why are both endpoints listed with the same IP addresses....Yet on the initial INVITE you got:

You got some SIP crazyness going on here that you need to clean up. SDP ends up choosing the appropriate media from what I can see. What is the overall flow of this system?

barry florence · ‎01-14-2015

Hi Brandon,

(2N Helios IP --10.1.4.93-2042) door system-> cucm(10.1.3.5)->DX650(3513-10.1.4.49-receptionphone)

Thanks for the reply, both the devices are registered to the same call manager(10.1.3.5) on the same site, thats reason it is showing the same ip address.

Thanks

Barry

Brandon Pierce · ‎01-14-2015

Ok, was unaware of your topology setup. That still doesn't explain the tear down of the call. What do the logs from the perspective of the Helios say if there are any?

barry florence · ‎01-14-2015

They gave up, as it is working with other phones, they expect to work on this one as well.

Thanks

Brandon Pierce · ‎01-14-2015

I know you said they gave up but I took a second whack at it. I see that you send out the initial SDP in the first INVITE but when CUCM gets it to pass it on to the DX650 there is no SDP for some reason. Are you using delayed offer or early offer? Finally, the DX650 comes back and offers everything back to the Helios.

You then get a CANCEL proceeded by an ACK with negotiated SDP but it's to late.

barry florence · ‎01-14-2015

Thanks for the reply. It looks based on the traces i can see it is using early offer between the Helios IP and CUCM, inbetween it uses delayed offer between CUCM and DX650 as in the previous attached callchart screenshot. i don't see any missing SDP's, please correct me if i am wrong

Barry,

I looked in detail at your logs and what I see is much more than how you have described this. Here is a more detailed sip ladder for this call flow. I have attached a clearer sip ladder diagram

Here is what this interprets as

And all sorts of things happened from there...

Here are the questions and suggestions

1. What is the CSF device on 10.0.0.74? Is this Jabber?

2. Is this a shared line between the jabber client and the Dx650

3. What seem to be happening is that the call is been extended to the Jabber device rather than terminating on the DX650.

Can you delete the extension number from the jabber client (for test purposes) and test again...

Please rate all useful posts

barry florence · ‎01-15-2015

Hi Ayodeji,

Thanks for the reply and detailed explanation. The extension is associated with a 8841 profile, dx650 phone and the csf windows jabber.

1. 10.0.0.74 is the jabber device

2. 3513 is associated with all the above 3 devices

3. when we answer in jabber, the call is working.

I have collected new logs with and without the jabber device, the logs for without the jabber device was at the time 9:07 .

Thanks

Hi Barry,

I have looked at the logs at 9.07 and it looks okay. So what is the issue when the call is sent to the DX650? What happens? No video? No Audio? How should the helios system work?

Ayodeji,

It is the same original issue even when we remove the jabber device, when someone pushes the button at the door entry system(10.1.4.93), it rings the dx650(10.1.4.49) and when someone answers, it gives a busy tone both at the dx650 and door entry( as in the traces3 logs 9:07). It works (both audio and video) for 8945 phone and windows jabber phones. The working scenario has to be as follows, when someone presses the button at door system, it rings the dx650 phone, when someone answer at the phone, user (dx650 user at 1st floor) will be able to see the video of the outside user, should be able to talk each other and the receptionist user dials a code to open the door.

Thanks

Hi Ayodeji,

I just tried few things(like enable and disable mtp on the device, reset the device), it seems to work now partially, i mean when someone pushes the button at the door entry system(10.1.4.93), it rings the dx650(10.1.4.49) and we can answer it, they can talk each other however no video on dx650. I have attached the new traces again. Video calling is enabled on the phone and video calls are working with other phone.

(2N Helios IP ) door system(2042)-> cucm->DX650(3517)

Thanks

The reason video is not working is because you have enabled MTP. The CUCM MTP doesn't seem to be able to support video hence the SDP sent to the DX650

This is the 200 ok sent to the helios, with video disabled. (please remove mtp, test again and send me the logs)

Hi Ayodeji

Mtp was unchecked previously at the device level(dx650), I don't why it invoked the mtp. As cucm mtp was at the mrgl in device level in previous trace, This time i have created a new mrg and mrgl without the cucm mtp and applied the mrgl at the device pool and device level, tested the call again, this time it is back to the original issue (when someone pushes the button at the door entry system(10.1.4.93), it rings the dx650(10.1.4.49) and when someone answers, it gives a busy tone both at the dx650 and door entry, (no audio or video). I have attached the traces as requested.

Thanks

This is really strange. I have gone over the logs again and everything looks okay. Its surprising that You don't have audio or video. You should atleast have audio. Please enable MTP so that you can atleast use the system even if its only audio that you get. I will continue to investigate this.
