Mr. Mohammad Saman
I am looking for a E1 channel bank with Answer supervision capability.
Could you please help me.11th December 2002 at 14:05 #20961JuniorGuest
check out http://www.pleiadescom.com for E1 channel banks with answer supervision.12th December 2002 at 00:23 #20962Mohammad SamanGuest
Try Pleiades P32MXI as TAC and Junior have mentioned above. They work quite well using a DSP voice/tone distinction algorithm. They are a bit expensive though. You might want to try to have design an add on piece for you. Essentially you need a filter that will differentiate between Voice and other signals on your 4Khz band. I am just trying to point out cheaper solutions.14th December 2002 at 00:48 #20963SamGuest
I found TENOR analog gateway which can communicate with CISCO
‘ comes with 4 or 8 ports FXO/FXS
ports , it gives answer supervision too , so U dont need channel Bank , it works only on H.323 , I think they are working on SIP too,
I think they have the best product21st December 2002 at 06:10 #20964jafon2kGuest
Are you certain that the TENOR has answer supervision (like the Pleaides does) or is it simply using timing to spoof answer supervision?
What price did you get the TENOR for?22nd December 2002 at 00:15 #20965Sam TomarGuest
According to new software Tenor can do real answer supervision on analog gateways only , 8 ports or 4 ports , by using this U dont need channel bank ,this can save lot of money , I am using only tenor for International VOIP application and I think they are the best in VOIP market23rd December 2002 at 03:07 #20966Mohammad SamanGuest
Ho HO HO ! Merry Christmas to all my Christian friends here 🙂 So can anyone tell me about this Tenor solution and a product number and pricing please ? Cheers !27th December 2002 at 20:43 #20967ChuckGuest
does anyone have some sample configs of the MC3810 forwarding a VOIP call to a 1750 with fxs’s
having problems routing the call.16th January 2003 at 01:53 #20968AlpGuest
I am also planning to use P32mxi with NMS AG4000 E1 Board. But I haven’t purchased the P32mxi yet. If you could get them to work together, can you send me the configuration?22nd January 2003 at 18:51 #20969GaryGuest
Around and around it goes! The bottom line is yes, the AS5300 does support the correct signaling for this configuration. Select E&M Immediate Start at the T1 controller. The CAC channel bank does operate under these conditions, but there are caveats. First, we assume that the CAC has FX0/DPT interface boards, and secondly, their is an assumtion that the analog lines have “Battery Reversal” on them. Mohamed had it right all along, the results given his configuration would be all calls are billable (and other problems), or if the leads are reversed on the analog lines then you get a one-way audio stream. This is so because Cisco does not connect through the audio channel until it get’s a connect message (A/B Bit Answer), so caller hears ring-back called party never hears. The solution was as indicated by severl postings, either buy an intelligent channel bank, or get “Battery Reversal” on the analog lines.21st February 2003 at 05:23 #20970JMDGuest
I have a clarent gateway connected to a Pleiades channel bank. Everything works fine except for when using the timers for answer supervision, we have one way voice until the timer expires, then the AB bits go high and the call is connected (2 way voice). IF anyone knows a work around for this please let me know. Thanks.21st February 2003 at 19:00 #20971tpGuest
what’s the actual meaning of answer supervision by the way? How does it help to solve the can can’t be released problem? anyone enlighten me please.22nd February 2003 at 14:42 #20972Hi all,Guest
I am still waiting any help about configuration P32mxi with NMS AG4000 E1 Board .
Thank you.26th February 2003 at 16:58 #20973jafon2kGuest
Attach the P32mxi craft cable to a computer running PcAnywhere.
Ken will be able to provide the support you need from there.
He is very good.
Have some country information available also.
Maybe send the country and city it is installed in to him in the e-mail before hand.26th February 2003 at 21:29 #20974JuniorGuest
For JMD :
the problem you are experiencing is caused by the network not creating the RTP voice path until the answer supervision is received. Since you are using the timer option instead of VAD you will not get a voice path until the timer expires which may be well after the caller has actually answered. There are two solutions. 1) find a way in Clarent to enable the RTP path (in Cisco this would be VOICE RTP SEND-RECV command) 2) Change to the better VAD approach which will cause the RTP to be created when the caller answers. Hope this helps.
