[cisco-voip] weird behaviour when dialing webex personal room SIP URI when logged into (webex) meetings tab in Jabber

[Lelio Fulgenzi]

Alright, it seems it’s hit and miss. I can’t narrow it down to failing when webex meetings tab is logged in. I did more tests and it sometimes failed when not logged in, and sometimes succeeded when logged in.

I’m going to have to work with my partner who’s helping to replicate and try to figure out what’s going on.

It looks like it works all the time with on-prem, but flaky with MRA.

Just checked. I don’t have any video systems saved in my profile.

When I dial another person’s CMR uri, e.g. roadrunner at acme.webex.com<mailto:roadrunner at acme.webex.com>, I see the familiar webex welcome screen and I’m told that the meeting room is not set up. More than likely, because they don’t have CMR enabled. But the call is getting to WebEx properly.

Is the coyote at uoguelph.ca<mailto:coyote at uoguelph.ca> URI a saved call back in your PMR (if it is, remove it then test)? Since the WebEx Meeting tab is just making REST calls to Webex, it seems like something is picking up on that session and “thinking” that you are trying call yourself.

If you are logged into the WebEx Meeting tab in jabber, and you call another PMR in the same WebEx site (not your PMR URI though), do you get the same behavior?

OK – This one is weird. Hopefully a simple fix.

I got things working so that when I log into Jabber as coyotes at jabber.acme.com<mailto:coyotes at jabber.acme.com>, I can “call” coyote at acme.webex.com<mailto:coyote at acme.webex.com> and it is sent to coyote’s personal room and I see the “enter your pin prompt”. Cool.

However, that only works if I choose to not log in to the WebEx Meetings tab on Jabber. If I do choose to log in, when I try dialing coyote at acme.webex.com<mailto:coyote at acme.webex.com>, it is changed (somewhere!) to dial coyote at uoguelph.ca<mailto:coyote at uoguelph.ca> which simple results in a call-waiting beep on my own line… yes, I’ve just called myself.

Has anyone seen this happen?

I’m pretty sure it’s happening either within CUCM or within Jabber itself.

I’m going to do some on-prem testing later to make sure what I’m seeing in Expressway is just MRA stuff.

Very weird.
