OVA 6.0.205.0

vMCD 7.1 13.1.0.33

I still have an issue with one way audio on outgoing calls. It's intermittent.
Wireshark shows the MBG handling SIP for incoming calls, but not for outgoing calls. Figured I needed to add MBG as outbound proxy. When I do, I can't make any outgoing calls. I get Out of Service on my display.

Network Element of Outbound Proxy:
Name..............MBG Trunk
Type..............Outbound Proxy
FQDN or IP........10.120.7.1 (MBG LAN)
Local............. False
Version
Zone................1
ARID
Outbound Proxy Transport...UDP
Outbound Proxy Port.....5060

Would i need to change / add anything in the SIP Network Element?

 
Further testing using a program called Sip Workbench. Workbench shows PBX trying to register via MBG but getting no response. I set outbound proxy in vMCD sip profile to MBG and changed Remote trunk endpoint in MBG to Registrar IP. No alarms raised this time, but getting "invalid" on display, no outgoing. Suspecting the credentials in MBG SIP Trunk are required for authentication to SIP provider. DOX say it's credentials just for PRACK.
 
Yes! That works. Been a long strange trip. This audio issue has been going on for awhile. I found that my SIP provider received compatible status from Mitel last month. After programming the PBX for that specific provider, things got worse and the system would reset every 10 minutes. Increased memory in vmware micollab host and added MBG as outgoing proxy today. So far so good.
