Obi AA does not recognize keypress when dialing in

(1/2) > >>

Hello,

I first noticed this issue in testing a config change that I was making to my Obi202 to setup a failover outbound dialing solution between my 2 SPs i.e. GV and CC. While that config change was successful and I did achieve my intended goal, inbound dialing to my CC line using my cell phone already defined on the CoT list revealed a non-working situation I am trying to remedy.

If I call my CC line using my cell, any keypresses are not being recognized by Obi AA whereas if I call my GV line, it works. What can I do to fix this or at least start the debugging?

Thanks,
Hiranmoy

HMishra,

You may need to experiment with the following setting in the CC Service Providers Profile:
Service Providers
    ITSP Profile A/B->DTMFMethod = ???

Well, I thought I already did albeit for outbound dialing!

The default value of Auto did not work, so as per some recommendation I found here on the forums, I changed it to InBand and additionally, also had to change Phone 1 Port -> Port Settings -> ChannelTxGain to 1. That seemed to do the trick for outbound calls.

I didn't think that any of that mattered for inbound calls to AA though. Apparently it does. It seems I need to keep experimenting with the selection(s). I am curious though about what is the experience of others having CC service and would appreciate if someone having CC service would chime in.

Thank you.

I don't have the answer, but this is the best explanation of how OBi deals with DTMF that I have seen:

In another post, mrjoe observes that some cell phones work calling into his OBi to aa and some do not! If you have a choice of cell phones, it might be interesting to see if a difference could be found.

This helps, at least in pointing out other permutations and combinations. I will experiment more and let others know. It is the least I can do since this forum has helped me so much.
