Can't make more than 4 calls

[Markee71]

Hi

have a client with an IPO 403 2.1(73), yes I know it needs upgrading, but as they work 24/7 it's not that straightforward.

Anyway, the systems has been running sweet for quite a few months - I get a call today

The majority ( 75%+ ) can only make 4 outgoing calls before the system stops them for a random length of time

I've rebooted, restored config etc all to no avail

any suggestions

TIA

Mark

Are they using pots lines? Did you check to see if all the lines are working. Just because its an IP Office, don't forget the basics.

 

[Markee71]

yup, it's a 10 channel isdn30

i've had users lay off so it's not just a 'lines full' situation

seems odd that it's only 4 outgoing calls

going bald here lol, thanks for the suggestion

i've been over everything i can think of basics wise ( hence redoing the config, i've seen too many corrupted configs for no apparent reason )

affects the analogue and DT users - but not the IP handsets at the end of a leased line (!)

Cheers

Hi, you are not call-recording to a 4 port vmail are you?

 

[Markee71]

nope

purely just people at desks making outgoing calls

 

[Ragnorak]

What happens to incoming when the outgoing stops working?

 

[Markee71]

as far as we can determine, nothing

phones still ring even if 1 or 2 handsets are 'dead'

 

[aarenot]

can you still make internal calls at this time.

 

[Ragnorak]

I would suspect it wasn't releasing the call appearances somehow, but on 2.1 you should be working with a 10 call limit regardless of appearance buttons.

What do you see on the phones? Does it say "Waiting for line" like there are no trunks available? Does it let you dial and just never complete the call? aarenot's question about whether you can call internally is a good one. Is it just calls? Can you turn DND on/off? Is the whole phone frozen?

Could it be a 30 port digital station module power issue? Maybe you recently added a phone and put yourself over the limit?

 

[Markee71]

Right, thanks for these, I've been back to my client and have the following information

After making the call, if you try to make another you get an 'engaged' tone - which to me sounded like they were dialling too quick "wrap-up time"

they have a basic 8port DT based 403 - with an analogue 30

and 5 IP hardphones at the end of a leased line

Symptoms appear on all handsets at different times, sometimes you can make 4 or 5 calls before you are stopped

you can't make any kind of call, pressing ANY button gives you the engaged tone ( DT, Analogue or IP )

The system has been running pretty much problem free for the past 6 months+ I'm the only one who has the switch password so I know no changes have been made

Thanks for all your help so far

 

[Markee71]

apparently - i've just been informed - it comes up with the engaged tone after you enter the first 4 digits of a telephone number

wish people would give you the right info first time, problem with being off site i suppose

 

[aarenot]

first suggestion, never rely on the users for data on the system. reproduce the scenario yourself, and draw your conclusions from there. if you can not reproduce, ask more questions, and or have them show you the scenario. often you find errors in reporting, or a user error which is the issue.
other thing to look at, the short codes, if the circuit has all the channels working, if all the circuits are already busy with calls. if the 4 digits are valid digits via the short codes. strange that the ip hard phones do not have this issue, does the call status app show the lines still connected. you have probably already looked at these, but thought i would mention them just in case.

 

[Markee71]

Thanks - checked all that before I posted

customers eh - who needs em, life would be so much easier.

BTW it DOES happen on the IP phones - see previous post

anybody got a lump hammer

thanks again, soon as I get any more info I'll post again

Have you tried to use Call status and System monitor to see what s happening on your lines/calls when the problem occurs ?

And i would test each outgoing line using diferent IDs and shortcodes for dialing them just to make sure.

Yaze.

Well, the saga progresses !!

BT in their infinite wisdom decided there wasn't anything wrong with the lines - but upon further 'interrogation' of my client BT called this morning " asking if everything was OK as a routine pass had detected issues on some of their lines !!!!!!!! "

anybody else smell fields and grass ???

I think that's going to be the end of this, as a friend from Avaya has been in and check everything is OK

But I'll keep you all informed - thanks again for everything

Only way to prove it - stick a Trend tester on the end of the PRI.

The 'four digit' scenario is because you are using 3 digit extension numbers. The IPO won't try to send to line until either the dial delay count or dial delay time have passed.

Sounds to me like BT are doing the usual "we can find nothing wrong" - then 10 minutes later it "fixes itself" .
