[Asterisk-Users] Calling CHRIS BARNET (PRI / E100P / ntl)

Wed May 12 08:41:58 MST 2004

Hi,

DR> Thanks for your Help Chris and thanks to Darren also...
DR> Now where did I put that receipt for my e100p?????

Whoa, relief *might* not be too far away... I'm installing some network
equipment on ISDN85 PRI circuits on Friday and whilst I'm at the switch site
I plan to capture a trace of the Asterisk/ISDN85 problem using an MPA
(portable SS7/PRI analyser). I already have the trace for a good ISDN110
(ETSI) connection and, in conjunction with the specs. from www.sinet.bt.com
, intend to spend some time early next week looking for a quick
fix/work-around.

I'm sure you'd like to make good use of those "freebie" PRI circuits with
something as flexible as Asterisk!?!

Watch this space...

Darren
PS. Telesoft have a nice protocol converter solution but it's really only
cost effective (with Asterisk) when converting multiple PRIs. They should be
e-mailing pricing over soon.

Hi Chris

Thanks for getting back to me :)

Sounds like your having the same sort of game I am with them.  Yeah I
tracked Darren down and called him myself (one helpful chap indeed!) and he
explained how the whole thing works.  Ive rang ntl back and got to speak to
one of the senior staff there who told me that the whole of the ntl network
is ISDN85 apart from one area (sorry guys I cant remember which one) which
is 110 and there is no information about their upgrade schedule.  So it
looks like for now until the new driver is written the E100P is not
compatible with the ntl in the UK :(

Believe me Id absolutely love to change Telco's but its not really
financially viable for me as I've got these pri lines rent free as part of a
bigger deal because we buy stacks of bandwidth from ntl.  Do you know the
irony is that there are talking about putting up the cost of my internet
bandwidth if I don’t start using their outdated pri service!

Thanks for your Help Chris and thanks to Darren also... Now where did I put
that receipt for my e100p?????

:)

Thanks guys

Darren Round
