Wating for Line issue with Avaya IP Office SIP 1

[AllenH12]

Hi There,

good day. i am new to IP Office 500 and SIP Lines.
few days ago, we have an issue with our Phone system when people tried to call outside, they got Waiting for Line displayed in they AVAYA 5410 phone.
i check the System Status, and i got an error: "No Free Channels were available Outgoing group ID 91."
then on the logs I found the below details,

“148102068mS CMCallEvt: 0.595697.0 116301 TargetingEP: StateChange: END=B CMCSIdle->CMCSOffering

I was suspecting that maybe we fully used our SIP Licenses, but when I check the License Status, there is no indication that the SIP Trunk Channels got congested.
I need help figure out what was the cause of this issue and prevent it in the future.

Many thanks!

Cannot reserve a codec for Bend, aend is 0.595696.0 116301 SujataJain.0

You did not use the correct codec.

BAZINGA!

I'm not insane, my mother had me tested!

 

[AllenH12]

yes the codec is correct. it was actually working fine, it only happen this particular time where in for almost half an hour, we cannot call outside. and after that, all calls went to normal.

 

[tlpeter]

Then there was an issue with the provider i guess.

BAZINGA!

I'm not insane, my mother had me tested!

 

[AllenH12]

ah ok. I have actually contacted the provider and they are looking in the issue, but at first they are insisting that it was an internal issue.
so i thought is was a license fully used up issue because i saw in the IP Office System Status > Service Errors

"The following System resources are in use: Voice Compression Channels (VCM)"

and

"No Free channels were available Outgoing group ID: 91"

during the time when we were having the issue.

 

[tlpeter]

No VCM channel can be the cause too as this can give codec problems too.
What type of phones do you use?

BAZINGA!

I'm not insane, my mother had me tested!

 

[AllenH12]

AVAYA 5410 an few pieces of 5420.

 

[tlpeter]

Then you need a VCM channel per phone per outgoing call.
So if you have more SIP trunk channels (and phones) then VCM channels then this will happens every time you reach the amount of VCM channels.

BAZINGA!

I'm not insane, my mother had me tested!

 

[AllenH12]

i have this licenses installed in our System

License Type Available Instances
Prefered Edition (Voicemail Pro) Unlimited
Phone Manager Pro IP Audio Enabled (Users) 2
Prefered Edition Additional Voicemail Ports 4
Phone Manager Pro (per seat) 3
IP500 VoiceNetworking Channels 12
SIP Trunk Channels 20
AVAYA IP Endpoints 24
Essential Edition Unlimited

i am not sure which one is VCM.

 

[hairlessupportmonkey]

do you even have a VCM card in the switch?

ACSS - SME
General Geek

 

[AllenH12]

would think that we have the VCM cards.

we have two locations each with 1 IPO controller and 3 IPO modules
and we have total of almost 100 users.

the issue only happens once. for 30 minutes and then it went back to normal.
maybe all the VCM channels are used up during that time?

thanks.

 

[smokinjoe2938]

Launch system status and go to resources, this will show you how many vcm's you currently have in the system

acss sme acis sme acss cm 5.2.1 acss cm and cmm acss aura messaging.

 

[AllenH12]

thank you!

I fund it. I have 18 VCM and SIP license is for 20 lines.
would running out of VCM can trigger a message to display Waiting_for_line in the users Phone?

thanks again for help.

 

[amriddle01]

Yes, if you didn't need them why would you have them in the first place? A VCM channel is required for every call between IP and DIG/Analogue devices

 

[AllenH12]

thank you very much. and my apologies for my ignorance, I am new to this.

what about this error:

"148102070mS CMARS: FindActiveARSByGroupID GroupID=91 - Not Found"
and
"148102071mS CMARS: LINE with group ID: 91 HAS NO CHANNEL: 34 - ATTEMPT OTHER TARGETS"

is this also related to VCM?

thanks again.

 

[intrigrant]

Yes, the first message you get when there are no available channels or resources for using this trunk and the second message tells ARS will try another route and the thirth related message is
148102072mS CMARS: No Alternate ARS Or User Priority lower than ARS Priority - Remain on the Current Form: SIP

which tells you that there is no alternative route available so you get the "No Lines" message.

 

[AllenH12]

Good Morning Everybody.

thank you very much for your reply. will close this thread now.

thanks again.
