Issue with Mitel and Avaya Interconnection

Hello everyone,
I'm currently having an interconnect issue between Mitel EX and Avaya. The SIP cluster has been successfully established. The problem is, when the Mitel SIP phone calls the Avaya phone, both parties communicate fine, and the same goes when Avaya calls back. In addition, when the Avaya extension calls the Mitel IP phone, both parties can communicate normally. , when a Mitel IP phone or operator console calls an Avaya extension, the call listens, but neither party hears the other. Packet capture shows audio is present. We are using the G.711U codec. Has anyone encountered this problem? Any suggestions for solutions?

1 Way or no speech is almost always a network or firewall problem.
is sip phone in same network as IP phone and console ?
if yes does it have same gateway as them
RTP is peer to peer so every device will need to be able to route its RTP to the avaya
where was the packet capture taken that has the RTP ?

I agree with Biliz66 - almost always 1-way or no-audio issues are a routing issue.
I recently had a site that replaced their DHCP server and the folks didn't set the voice network option 3 for Default Gateway. As phones renewed their lease, they removed the default gateway causing 1-way audio on external calls though a SIP peer through an Adtran router as an SBC.
When I found that the default gateway was missing on the phones, they added it to the DHCP server and restarted the phones in question - this resolved their issue.
