make the below message formal


Thanks for your help. As discussed over the phone, 
Initially, the incoming calls were showing up but they were not getting connected to the audio.
For the outbound calls, we've tried calling but there was no response. This has been going on for an hour.
After the first call, the issue appeared to be resolved. But later the same thing happened.

The calls now appear to be going through. We will let you know if we face any issues.

Thanks & Regards
