We have a sort of unique application with a mobile radio system. We are using Tait radios, with a Tait DAS (Digital Audio Switch) connected with T1 to a VWIC in order for the router to convert a radio call coming in on TDM to a multicast session to Console units. The radio calls works most of the time, but for some unknown reason the router is periodically dropping connections from the TDM. I am trying to find debugs that will tell me what is going on, and ideas as to why the router is dropping audio. Here is the corresponding configurations:
card type t1 0 0
network-clock-participate wic 0
controller T1 0/0/0 cablelength short 110 ds0-group 0 timeslots 1 type e&m-immediate-start ds0-group 1 timeslots 2 type e&m-immediate-start ds0-group 2 timeslots 3 type e&m-immediate-start ds0-group 3 timeslots 4 type e&m-immediate-start ds0-group 4 timeslots 5 type e&m-immediate-start ds0-group 5 timeslots 6 type e&m-immediate-start
! continues through ds0-group 23

dial-peer voice 1115 voip destination-pattern 1115 session protocol multicast session target ipv4:220.127.116.11:22516 codec g711ulaw vad aggressive
The channels should be trunked at all times. can you elaborate on what you see when the connection is "dropped from the TDM" side? Are you seeing the trunks go down? What do you do to get the system back up?
sorry, i have been on the phone with Cisco all day. My original configurations
were based on configurations supplied to me by the console maker, TPS, and looks to be somewhat old. The ds0 groups were configured at E&M Immediate-start, and Cisco changed them to e&m lmr. This seems to have fixed the problem.
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
