[saif musa]

Hello Community,

    We got cisco router 2600 with NMHDA-4FXO ports. when configuring FXO ports to work in trunk group 1. it doesn’t reset to free channels despite of hunt scheme type. Iv found that some people referring to BUG CSCec46726. what is that ?? and how we could identify my technical issue if its related to BUG ??

Hello Saif,

I have attached a snapshot of the bug.  It does affect 2600 routers,  however there are are a lot of known fixed releases.

hope this helps,

please rate helpful posts

thanks

When using trunkgroup on VIC-2FXO series modules set for groundstart signaling,

no further calls can be made after all the members of the trunkgroup have been

used. Using the command "show trunk group" shows there are no free channels.

You can see that the voice ports are on-hook by using the "show voice port sum"

command.

Workarounds:

1. Use traditional huntstop and preferences under the dial peers.

2. Use loopstart signaling and a different method of disconnect supervision.

3. Use a NM-HDA module.

CHARLES,

Thanks for responding..

Really I changed the signal type on FXO port to loopstart but still the same issue. ports didnt reset to free channels after calls ended. Im start thinking of compatibility issue. could you help me with that also ?
