Mitel MiVoice Business/MCD/3300 / Trouble With RTP
« on: October 29, 2024, 01:02:25 PM »
Hello,
I am tying to figure out an issue that I am having with an SMBC and some SIP trunks.
I have an SMBC on a customers LAN, without an MBG. It communicates out through a firewall to register with the SIP provider.
I am troubleshooting an issue where inbound calls need to get transferred back out to an external number, and when this transfer is made all audio gets lost. I have gone through the PCAPs I could pull out of the SMBC, and the PCAPS from the SIP provider side. So far, all I have been able to determine is that RTP packets are not flowing once the transfer operation completes.
Does anyone have any input on how to troubleshoot this, or forms and fields to check?
Any help would be greatly appreciated!
