Multiple services on single MBG server (SIP proxy and SRC )

[ferhan.n]

Hello, I was wondering if it is possible to run 2 services : SIP proxy and SRC over the same MBG server. According to MBG documentation it is possible, but according to regional Mitel support office it should not be done this way because its not  the common practice.

I have to install it on single server because we are running low on server space inside the rack.
Any thoughts?

Are you deploying this in LAN mode, DMZ mode or Gateway mode?

It will be LAN mode, there is no connection to any external PABX or IP phone. The only external link will be with the SIP provider. But i guess that can configured in LAN mode since i saw an option to override the interface address for SIP trunks. We have 4 network interfaces on that server.

Mitel will only support SRC on a standalone MBG

Having both SIP and SRC on same box can cause problems with speech on recorded calls

I hope the traffic is not going to pass through a SIP-aware firewall.

In LAN mode MBG will listen for traffic on a single NIC, but if you add an RTP override on a SIP trunk you can make it bind to that corresponding interface as well. The rest is just routing.

Both news to me. I don't see why that would be.

Can you explain how it can cause problems? correct me if i am wrong but the ports and interfaces used will be different as far as i know.

If you check the latest eng guide you will see that it not listed as a supported config

Also after speaking with TAC

As src is only supported in LAN ONLY mode the MBG may sometimes try to send voice traffic for SIP proxy via the lan connection


I have seen this myself and was told by TAC that we must change it

As per my last message i have seen it where if the customer is trying to run SRC and SIP on the Same MBG SIP traffic can be seen trying to go via the LAN port not the WAN port

As i said spoke to TAC and they advised that it was not a supported config
