Re: [cisco-voip] Native Call Queuing on UCM 12.5 with SIP Trunks

[Pawlowski, Adam]

We went from 15.4(3)M9 to 15.7(3)M4b

Noted also in this version that we previously allowed video/media to flow to 
the CUBE just in case we were ever to use it for routing media calls, and this 
version (15.7) drops calls from Jabber, etc when we place them on hold.

TAC said it was something to do with the number of options in the SDP changing 
and it being a protocol violation. The IEC error and Q code did sort of 
indicate this, but, as to why Cisco's systems don't want to play nice protocol 
wise with each other I don't know.

Adam,

I've not encountered the streaming issue with a SIP trunk, just H.323.. 
interesting.

Out of curiosity, what code level in the ISR G2 did you go to when you 
encountered this? The behavior of simplex streaming is to send a null/fake IP 
address in the logic channel multimedia control message, which for anything 
required to check incoming RTP packets against the IP/port would fail (creating 
the silent MoH condition) which I was under the impression was only the G3 ISRs.

Thanks,

Ryan

After an upgrade on our CUBE to a later IOS (ISR G2) we needed to have the 
duplex streaming parameter enabled for MOH/Ringback to work properly.



I believe there is a note about that being needed for the 4400 series gateways 
as well, but, I know we didn't have it before but needed it at some point to 
get media to be heard properly by the far end in a network hold kind of 
situation.

Does the problem go away if you force an MTP?



Can you provide a debug ccsip messages of an external call?



Can you share your sanitized CUBE config?



Curious if your call/media is changing after the initial announcement and your 
ITSP doesn't care for the way you're attempting to change it.

Hi all,



This being back on the tools is doing my head in. I think I've been away too 
long.



So I have configured native call queuing on UCM 12.5.x

Internal calls queue fine. The initial announcement plays. Period announcements 
work and the MOH is fine in between.



External calls hear the initial announcement.

There is no MOH after the announcement and the external user has ring-back tone.

There is no periodic announcement.



Any thoughts on why internal is okay and external is not working? Is it 
relating to SIP supplementary services?



Cheers

Dana

Re: [cisco-voip] Native Call Queuing on UCM 12.5 with SIP Trunks

[Ryan Huff]

Mark,

That is a good thought.. there are a few scenarios where a CUCM/CUC.. etc mid 
call change will advertise a "no media change" reINVITE out to the PSTN. While 
I don't think that would be the case here (I would expect the peer to drop the 
call because they couldn't negotiate the null/0.0.0.0 media address), SIP 
traces would certainly show if it were. If it were the case, likely under voice 
service voip >> sip the syntax midcall-signaling passthru media-change would 
prevent mid call signaling from egressing the CUBE unless it actually had 
legitimate media changes.

Re: [cisco-voip] Native Call Queuing on UCM 12.5 with SIP Trunks

[Ryan Huff]

Additionally, If it’s a custom MoH (not the built in Cisco tune), make sure the 
file is uploaded to each CUCM server individually; the working phone 2 phone 
scenario could be happening on nodes where the moh file is, and the trunk 
registered to a node where it is not.

Thanks,

Ryan

Hi,

Try to check if your trunk has access to moh resources.

This means your trunk needs to be placed inside a device pool whose mrgl 
contains at least one mrg containing at least one moh server.

Sip trunk > device pool > mrgl > mrg > moh server.

Additional test: call some external party through your sip trunk and try to put 
called party on hold. Does the called party hear moh?
