VTL between 2 NBXs DID issue no voice mail

 I am having an Issue that when people call in on DID through T1 card on NBX 3000 and are transferred though VTL another v3000  they do not get voice mail message I have 2 NBX v3000 they were on R6_5_22 and was looking for P03 to download and can not find it to see if it will fix my problem.  Last night I took the 2 systems back to R6_0_63 and still having issues.  

 

This setup was working fine since 2006 nothing has changed but this functionally has stopped working sometime in the last month. If the DID calls they can answer the phone just fine but if they don’t there it answers but no outgoing voicemail plays and nothing gets recorded and no keys do anything.   

 

Thank you for any help that you can give.

Re: VTL between 2 NBXs DID issue no voice mail

Hmmm...

 

what happens after say 4 rings or so ? where does the call end up ?

 

Nothing changed , so I would guess that it may be table members  like vmail ports or the way the calls are routing .  If the tel rings then it should go to vmail automatically .

 

Check the table and make sure in the devices using the correct devices ar ein there , table 1 & 2 . Maybe someone removed the vmail prots or changed them .  Look in both systems and see if they are the same to start with ....

Re: VTL between 2 NBXs DID issue no voice mail

After 4 or 5 rings it just beeps no outgoing message no commands work either * # or 0.  If I call my DID and answer and transfer to the remote extension it also does not go to voicemail same beep no outgoing message but if I dial from my phone the remote extension I can get voicemail Outgoing message and leave a message.  I have restored the old Dial Plans and that did not do anything.  I am calling the phone company to see if they changed anything.  

 

Let me know if looking at my dial plans will help. 

Thanks for the fast reply.

Re: VTL between 2 NBXs DID issue no voice mail

Just a beep when you trasnfer a caller from site 1 to site 2 , but internally the call goes correctly to voicemail ?

 

Hmmm .... Now thats a good one .....

 

Only difference would be table 2 as that controls inbound calling , but I am now not sure about a dial plan issue per what you describe .

 

Only on inbound calls to the remote location you get a beep ? Not dead air or some sort of strange noise , but a beep ?

 

Any network changes done ?

Any telco changes but I do not think this is a telco issue at all

Interesting how it just started happening ....

How many tels in the remote location ?

Is this a business rmeote location or someones home ?

can you describe how you connect to the remote location please ?

Re: VTL between 2 NBXs DID issue no voice mail

The only way to get to the bottom of this issue is a network trace on both sides....not an easy thing to do !!!

You will see where the audio is going..

YOu may be able to get by with just doing one side, the receiving side.. do the trace so you are getting all input /output from the NBX...

 

one other thing to try, dial the number , you hear nothing. however, if you hit the # sign, are you able to leave a message????

Any network changes done ? nothing changed on the network

Any telco changes but I do not think this is a telco issue at all  they said nothing changed on there end but they ran test on our lines

Interesting how it just started happening ....

How many tels in the remote location ? there are about 10 to 15

Is this a business rmeote location or someones home ? it is another office tied through a point to point t1 through 2 3com 3016 routers with a NBX v3000 at each office 

can you describe how you connect to the remote location please ?it is another office tied through a point to point t1 through 2 3com 3016 routers with a NBX v3000 at each office

Re: VTL between 2 NBXs DID issue no voice mail

I agree in reto the traces . Also , is this occurring in all tels at the remote site ?

Re: VTL between 2 NBXs DID issue no voice mail

I am trying to figure out how to run traces.  Today I watched the VTL Status on both sides on main Site the call goes out on last VTL and on remote site it comes into the first VTL.  I also watched the NBX messaging Configure Status and saw the extension number, username  in the Used By section on the last voice mail port.  This it telling me that at least the system is attempting to work correctly.  I also tried calling directly into the remote NBX and then transfered to an extension and I watched on the Voice  Mail configure Status, the last port was auto attendent and the next to last port was the users mailbox and it played the outgoing message and I was  able to record a message.  I was also able to transfer to the main site from the remote site  and leave a voicemail so comunication going that way is fine.

 

Is there a site that can help me with a network trace?

Re: VTL between 2 NBXs DID issue no voice mail

Ok I just tried something and figured out it is something to do with my digital t1 PRI line card.  I plugged in a pots line into the main nbx v3000 and was able to get transferred and leave a voicemail at the remote site. 

I have reset the card gateway chassis but it did not help.  So it seems like the VTL and voicemail are ok, it is something in the Digital line card.

Re: VTL between 2 NBXs DID issue no voice mail

The issue you describe, call from PRI card into NBX, then across VTL to another NBX not getting vm announcement is an old one that was fixed in 6.0.63.. make sure that both systems are running 6.5.22.

Also, can you check your pretranslator?? are there any "-" or "z" in the pretranslator.. as weird as this sounds, there was an issue that if a "-" or "Z" in pretranslator, no vm announcement.

Re: VTL between 2 NBXs DID issue no voice mail

No" - "or " Z" in pretranslator's dialplan.  I am on R6.0.63 now I was on R6.5.22 but took it back when first troubleshooting I will re upgrade the systems tonight.  I am waiting on my phone company to verify the PRI settings and to see if they changed anything that would cause this issue.

Re: VTL between 2 NBXs DID issue no voice mail

I re upgraded to r6.5.22 last night after changing my PRI settings to more closely match the phone company settings.

I had

CO Switch Protocol: AT&T Custom - 5ESS   Framing Type: ESF - Extended Super Frame Line Code: B8ZS Line Length: 55-95 Meters Timing Mode: Loop Codec: G.711 mU-Law

The phone company said it there is

NI2 , ESF, B8ZS, and Timing Mode Slave (which I only get Loop or Internal as options)  I still have the lack of out going message and cannot leave voicemails on the remote office system.  I might just setup phantom voicemail boxes to get by not sure what else to do.

 

 

Thanks.

Re: VTL between 2 NBXs DID issue no voice mail

you should open a case with HP... we will need network traces from both sides.. that will show what is going on.

Re: VTL between 2 NBXs DID issue no voice mail

Not sure on how to do network trace, or how to contact HP on this since I bought this back when it was 3com in 2006 with a 3 year warranty so It is out of warranty.  Any info on these would be extremely helpful.

Did you have any luck in resolving this issues?  I have the same exact issue getting calls into voicemail over VTLs from the PRI.

Re: VTL between 2 NBXs DID issue no voice mail

Unfortunately at this point , a trace would prob be your best bet ... Open a case , and we can walk you thur some stuff like vtl logging and traces in order to see why the vmail is sending a beep . Have not heard this occurring on a vtl for a while as bosoxfan mentioned an older bug . But it was stuill a reare one as not too many folks have experienced this that I know of . what kind of data switches ? what kind fo routers ? All codes on the network updated to the latest ? what kind of nbx platform ? How many nbx'es in your network ? Of course the code you are running ? How many tels ? type of tels ? Pri ? Analog lines ? specs on the PRI ? Type of PRI board ? ( rev Letter ) 3C10116 C or D ?

Re: VTL between 2 NBXs DID issue no voice mail

I have been talking to the phone company and they have checked everything.  I did a workaround where the voicemail is hosted at main site so it is working by someone calls into the PRI at site A it gets transferred to site B and if they do not answer it then forwards back to site A phantom VM.  It is working for now I will keep testing to see if I can ever figure out what happened.  I have watched the VTL screens and saw the handoffs to voicemail just do not know how to explain it.  

 

Equipment

Site A

NBX v3000

SW: R6_5_22 Network Protocol: IP-on-the-fly File system NBXFSV1 

31219166AA Chassis 3c10200  

Digital Line card  part # 3C10116D Board Type: ISDN PRI Model Number: 0x0e00 Status: Online Software Version: R6_5_22  

Phone Company supplies a PRI  

Interconnectivity Point to point t1 with 2x 3com 3016 routers 3Com Router Software Extended_V1.30  

Both voice and data go through 

 

Site B 

NBX v3000 

SW: R6_5_22 Network Protocol: IP-on-the-fly File System: NBXFSV2  

2 analog lines for 911 at that location.

 

As I said before just seems to only hapen when calling into PRI and transfer to site B, Site A is ok voicemail works properly.  If I hook up an Analog line into site A call in then transfer to site B extension everything works normaly.  

 

Interface Type: T1 CO Switch Protocol:National ISDN - NI1/NI2  it was AT&T custom 4ESS but they told me it should be NI2

Framing Type: ESF - Extended Super Frame 

Line Code: B8ZS

Line Length: 55- 95 Meters  they did not give this to me

Timing Mode: Loop

Codec: G.711 mU-Law

On Line

Num Channels:     23

Num On Line:      23

Num Off Line:      0               

Call-By-Call Service Config (4ESS only)    

Unchecked Enable Call-By-Call Service

Carrier Identification Code*     "(BLANK)"

Default Outbound Service:       Standard (LDS)

* AT&T code = 288,See Help for details 


Let me know if there is anything else I can get to you.

 

Thank you.

Re: VTL between 2 NBXs DID issue no voice mail

I did not resolve it if you figure anything out let me know and I can try it.  I am getting calls to go to voicemail over PRI at Site A where it comes in.  I only have problems when the go over vtl to another site is when the voicemail just beeps if you hit  #1 otherwise it is dead air and nothing gets recorded.
