Inbound sip calls from ITSP are not disconnecting on the IP phone

SamuelR871 — Sun, 25 Oct 2020 11:11:48 +0000

Hi Guys,

I'm quite new to sip/cucm/gateways and I'm trying to learn in a home lab environment. I'm currently running a VG202 (ios 15.1) with some basic config, and cucm 8.6.

My config is successful enough to allow inbound and outbound calls, with audio in both directions (thanks to some winning guides on UCPros) but I'm having an issue with inbound calls from the ITSP side.

When the inbound calls disconnects, the call remains active on the IP Phone for around 20 seconds before it clears, even though the calling party has already ended the call at their end. It doesn't do this on outbound calls - and I can't seem to identify the issue.

Is there anyone on the forum that could take a look at my config and check I haven't missed anything obvious? I've attached the config and sanitised it.

Equally, I'm not sure if it's something within the CUCM trunk that might be causing the issue - I'm quite new to this, and still learning.

Any advice or guidance would be greatly appreciated :)

Samuel

ISP SIP Gateway inbound calls failing on CCUM

darrenseales — Thu, 22 Oct 2020 12:55:03 +0000

Hi, I have recently built a CCUM V12 server for a small IPT environment. It has been a number of years since I worked with CCUM and then it was just H323 gateways with SIP trunks starting to be born. I loved the Call manager but since that role I never had to support a CCUM until now. My issue is that I have 2 x SIP trunks that are managed including the gateway via a ISP. Which I have added to the CCUM and all outbound calls I configured for so far with the RP, RL, RG are all working OK. However all inbound calls fail. When talking to the ISP they say they can see my test calls coming in and being passed to the CCUM. I have researched and looked over my config on the CCUM and cannot find any issues.

Has anyone had this experience and have any ideas how to resolve?

Darren.

vCUBE and xcoding, conferencing

Hi,

Does anybody knows if we could use Cisco vCUBE with Call Manager software media resources for Conferencing and Transcoding? I've been able to register MTP profile, but configuration don't seem to allow me to configure xcode and Conferencing.

Wanted to confirm if it's possible as I can't find it on Cisco doc.

Thanks

Oscar

Write a - "how to report an issue/request" guide

Pasha Teplitsky — Wed, 30 Oct 2019 14:02:58 +0000

We need help writing a short guide that would help to make the requests and reports standardized (version/steps taken etc).

If you have some QA background you probably know what I'm talking about.
If not, just common sense would be good to start with.

Help find a proper license for the tools

These tools are meant to be open-source.
We want them available for everyone, but we don't want people to add a row to monetize them.

Got any ideas on how to properly license the tools? do share.
