Telecommuter mode and analgue trunks issue - beware! 1

[oldtimers]

For Telecommuter mode Avaya state:
"Phone Manager Pro allows the making and receiving of calls and the retrieving of voicemails from an external phone number as if they were in the office, with Phone Manager providing the call control. The typical scenario is the remote worker that occasionally works from home or from a hotel room."

It's very good if you use ISDN trunks, but is not so good with analogue trunks.

My disti says that the only way this works for analogue lines is in "Continuous mode". This means that the line from the IP Office has to be up all the time before calls can be made out to other parties.

If someone knows of a work arround please advise otherwise BEWARE of this design limitation.

We just stumbled on this limitation as well but thought it might have been due to loop-start emulation on the far end line. This certainly clarifies it a bit.


Sounds a lot like a feature that we thought would be great for clients until we deployed it -- Mobile twinning. Great if you're using a PRI, crap if you have analog lines.

Thanks oldtimer!

Anything that involves trunk to trunk connection is never going to work well with Alog lines.

It's for things like this that we install ISDN almost by default in the UK. We only put in alog lines for very small customers.

same,

i have only ever installed a system onto alog lines if they were already there and the customer didnt want to change.

had huge headaches with a system that had 20 users and 20 alog trunks, YUK! took us ages to convince them to get an isdn circuit

I can't think of a single IPO we have with Alog lines. We have some Pana's and Ericsson's on alog lines.

For the record forwarding works over analogue trunks and there is a tick box for trunk to trunk connections.

Addditionally UK is going to BT21CN which is all IP based so why convert analogue lines to a nearly redundant technology?

Thanks

ive been hearing about 21cn for so long now.

not seen anything positive actually happen,

and i would convert alog to isdn even a week before 21cn goes live, because i then wouldnt spend that week troubleshooting

I'll think you'll find Analogue is closer to redundant than ISDN, BT will never drop something that makes them so much money, they are not that stupid despite the fact that's how they appear when they try dodging faults.

I agree Tom.

I was told 2 years ago on a course that everyone will HAVE to change thier phone system for a SIP compliant one within 3 years.

That leaves a year left. I can't see it happening. I don't think I will fully trust SIP in 2 years never mind now. If we install SIP we recommend some ISDN as backup.

Besides which, BT won't finish 21CN for at least 3 years, they are already well behind schedule!!!

last i heard they upgraded an exchange in cardiff, and lets say it didnt go to plan....

never heard a peep since

i seem to remember being told that 09 was the time that people would start seeing LLU lines being dropped into their houses instead of alog.

09 isnt really that far away now and nothing seems to have progressed,

analog lines have more features in North America then they have in Europe so I doubt that they will get replaced as quickly, but I think there will be a reduction in customers hanging on their analog lines for security reasons so they can plug a phone in just in case there is another big blackout (5 years on the day btw).

FHandw., ACS

If you can't be good, be good at it!

Get a SIP line for the Telecomutermode or trunk to trunk transfer.
