Hi all,
My company is trying to configure intercom to work between an on-prem 8851 phone and an off-prep 8851 phone registered through MRA/Expressways.
The off-prep MRA 8851 is able to successfully intercom to the on-prem 8851 and two-way audio is possible once the on-prem 8851 accepts the intercom request. However, when the on-prem 8851 tries to intercom to the off-prep MRA 8851, a message is heard immediately saying "this call cannot be completed as dialed" and a 404 not found error is seen in log.
Has anyone been able to make this work or have any ideas to try?
