Wow.. a couple of things
1. you do not have enough voicemail ports.. you should check. You should go to NBX Messaging/Configure/Port Usage and check how many times you ahve hit the max. number of vm ports.
2. the "routing" errors to 5000faaaaa4#extnumber.... are calls going to a persons voicemai.. probably related to item 1 above.
3. you have a routing error to 9050xxxxxx... check dialplan.. 9050xxxx goes to route 1, which is *0001, then
it stripleads 1 digit so sends out 050xxxx. .is this ok in your country
4. your original issue, call coming in, then hit dtmf not being recognized.. it is difficult to match that action with
an error here... can you match? run test and see what is new in the router log.. but there are a lot of calls not getting routed.
5. as for everything timing out going to x100.. you probably have that in your AA Menu tree.... timeout usually goes to the lowest extension number, which by default is the operators extension. You can change that by going to the AA/Menu tree
6. as for the disconnect, the US country pack uses a "Supervisory" disconnect.. UAE country pack uses a tone disconnect... so, with the US country pack your calls would not be disconnected because the telco is sending a tone disconnect.... this was for a test to see if the dtmf's would come through
