SIP trunk calls are disconnected on Mitel EXTs and Analog EXTs

[MarvinJK]

Hello

# 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 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!

Sounds like a codec mismatch

Hi Lundah

I have tried many ways in the codec settings, even removing all and just keeping G.711a and G.711u as system default, the problem is still same.

Looking for advice
Thank you very much

sip trunk trace might be helpful
still might be codec related - can you limit the codecs on the sip peer to 711a 711u
any difference in networks between minet phones and the sip ones
do they live in same subnet and use same gateway address

might be a speech path problem
signalling able to setup the call as its via teh MIVB
then speech path cant connect as its peer-peer between phone and sip trunk

are you using a mbg as a sip proxy ?
whats the carrier for the sip trunks

If I never did anything I'd never done before , I'd never do anything.....

Hi Billz66

It's Oki right now, I adjust the Codec and answer / responses in SDP Options

Thank you so much!
