  Chances are that calls from town B are having some issue like you mention either a SS7 or non end-to-end ISDN issue.

This document discusses this for h323 gateway.

  No one way audio issues at all..
  That is what led me to an SS7 or telco issue

  IP Routing is enabled..

      Hello;

     

    for you one way ringing issue if u answer the call both partiesn here each other or the call is also one way Audio??

    Also have a look at this

    http://cisco.com/en/US/tech/tk652/tk698/technologies_tech_note09186a008009484b.shtml 

     

    I had a problem like this, my problem was one way audio and belive it or not the problem was with the GW and voice gateway donot disable IP Routing on it (no ip routing command) with no obviuos resason. I was disabling the IP Routing and I had this problem and once I enabled it the problem disappears.

     


        Thanks and Best Regards

    Hello,
I was looking at a CDR reporting issue today, and I am a little stumped.
The calls in question are disconnects. And hang-ups.
We want to be able to show those calls are being made.
They are not showing up in the CDR records.
>From what I know, they should show up if the zero duration flag is set.

But that does not appear to be happening.
Thoughts?

Next I have a most intriguing problem.
Customer is using CCM3.1(yea I know it's old)
1 full PRI on a 3600.
Ckt is from Provider A.
In town A.
If a call comes in from town b, in a different Lata the caller does not
hear rings, but the calls ring in.
If a call comes in from town a, the callers hear ringing.
Callers on both are using the same provider.

Now for the fun part.
Cell phone caller #1 is using Verizon, caller hears ring.
Cell phone caller #2 is using Sprint, caller hears ring
Cell Phone caller #3 is using suncom, caller DOES NOT hear ring.

It has been awhile, but I remember Suncom and Cincgular have their
switch for the area in town b.
Verizon and Sprint have their switch in town A...
I suspect somekind of SS7 issue.

Town a, and town b both have a dial-and-toll CO and the end user is
located off a tandem switch that is connected off of

Anyone seen this stuff before?

Later,
Jim
