Title: SIP trunk calls are disconnected on Mitel phone EXTs and Analog phone EXTs
Post by: hvm2809 on May 17, 2024, 12:10:32 AM

# The system information:
- MiVoice Business Release level: 10.0 SP1
- Active software load:10.0.1.22 (21.0.1.50)
- Platform: SMBC 7963MB of RAM

# The incoming and outgoing calls via CO line / Analog trunk is OKI

# The PROBLEM with SIP trunk calls:
- Incoming / outgoing calls to / from a SIP phone EXT is OKI
- Incoming calls to a Mitel 5300, 6900 or Analog device EXT: the EXT rings -> picks up handset -> call is disconnected
- Outgoing calls from phone 5300, 6900 or Analog EXT: called phone rings -> answer -> call is disconnected

Please give me advice and support?

Thank you very much in advance!

If the phone rings, means the setup for the call is good, after the audio will stream from the set to whatever called. I agree a pcap will help.

Is the call actually disconnected or is it a no audio situation?
