486 busy here
Hello All
Would you care help me sorting out the following ADSL customer complaint:
- UAC "A" is registered on my SBC
- UAC "A" calls B Number (mobile or PSTN number)
- the call goes fine
- the B side hang up the call
- UAC "A" didn't hang up the phone
Here at the fourth step the call should be released at both side. but this is not the case.
In fact when the B side tries again to call the UAC "A" it finds it as Busy.
Any clues?
