Office 250 with 6900 series phones

[stricklandhtcinc]

I'm having issues with on way audio on 6900 series phones on a Mitel Office 250. Internal and External Calls.
Any Suggestion's?

Based on my limited knowledge about 69xx with the MiVoice Office 250, these essentially register as a SIP extension with the help of the MCS server.

They do allow for port mirroring on the sets so it may be worth doing some packet traces from there and also on the set itself (it port mirrors to the PC port iirc) to see at what point the RTP is dropping.

What is the network settings for the Mitel 250, MiVoice Office App Suite and your phones.  I would suspect a gateway or subnet mask issue.
