sundance-communications.com/forum Forums Other TDM Phone Systems Telrad Telephones & Systems Replacing dedicated PtP with PSTN

My client currently has a T1 PtP and the telrad's (400 & 128) were networked.

400 had 2xx and 3xx
128 had 4xx

I changed prefix routing from the network trunk group to Routing Tables (2,3 and 4) respectivly, which do a LCR translation to 121255550xx (delete 2, prepend 121255550)

Only problem I have is that they dont have the "0000" number in one of the blocks, so when then dial 300 it goes to the wrong place.

I tried using Dialed Number translation table to map 300 to 399 and then define the xx99 DID on the other side to map back to 300, but didnt't work

Its my understanding that the DNTT is susposed to happen "after the prefix, but before the LCR Routing"

Any suggestions

You still using T1 cards on both systems? What software levels? Any thought about really saving them monthly cost of T1's and networking with TVsE over IP?

SSP,

Eventually i'm migrating them off of Telrad and onto Asterisk. Im dropping the PtP T1 for cost savings, since we only use about 3000/min/month now and I can do that PSTN for about $80 vs the 350 for the loop. Also it free's up my T1 cards for the asterisk interconnect.

I have given up on telrad and their VoIP solution. Know anyone who wants to buy a TvSE and 10 phones (24 button display, IP)

In the mean time, any ideas how to configure the dialed number translation ?

Thanks
