One Way speech issue

[installer111]

Hi,

I installed MBG with MiVoice 3300 for public SIP trunking purposes, I am facing a one way speech issue.
any help?

Try disabling prack support on the MiVB (by enabling the "Disable Reliable Provisional Responses" option in SIP Peer Profile / Signaling and Header Manipulation)

Then try disabling prack on the MBG.

public sip trunking purposes"

does this mean that the Trunk is regsistering via the internet?
how is the server deployed?
- lan mode single NIC)in voice
- DMZ mode single NIC in DMZ
- server gateway 2 NICS one internal one conencted to internet with Public IP natively assigned

Whats between the server and the internet ?
if there is a firewall are the appro[riate ports open?


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

Thank you for your reply

@techymitel , I will try and feedback you.

@Billz66
- This is a dedicated SIP circuit towards the provider
- MBG deployed as server gateway with a LAN and a WAN interface.
- Nothing between the server and the internet,

One question regarding RTP traffic, shall I initiate a connection between the 3300 and the provider? or does all traffic go through MBG ?

Did you build a proxy in the 3300?

BAZINGA!

I'm not insane, my mother had me tested!

Issue solved, it was related to trusted networks part in the MBG

Thank you all.
