Please does anyone have a recent document that describes the DMA External H.323 integration with Avaya Aura. Documents i have seen on the internet and with this community all refer to CMA and Avaya. I suppose there is something that addresses DMA specifially.
The partnership between Avaya and Polycom ended about 4 years ago or so. Therefore no new documentation was been delievered. The CMA only integrated with Avaya using H323. For this reason, the Avaya Call MAnager (ACM) was used. The DMA can be integrated using either H323 or SIP. Generally we prefer the DMA to use SIP. This requires the Avaya Session Manager as part of the Avaya Aura platform.
If youwant to support only in-bound calls to the DMA, then no DMA configuration has to be done. All the configuration is done on the Avaya side. But, if you want to support out-bound calls from DMA to the Avaya, then you will need to create a DMA external SIP peer which is a SIP trunk to the Avaya.
I can attach a doc I have which is a tad dated, but it may help.
I have an external SIP peer configured on my dma that points to my Avaya Session Manager. Then a dial rule setup with a prefix service to route to avaya session manager when the prefix is used. The dial rule strips the prefix and sends the digits to session manager
I had to create a SIP user on Avaya for the sip peer config on DMA. The SIP peer can be configured on DMA under Integrations>external sip peers
