Peers in expressway zone to CMS

[robert.klopsch]

Hi community,

we are currently in the process integrating CMS in to our environment.

Previously we use conductor and 8 vTPS on 8 MM410v blades.

So we want use these blade for our CMS environment and implement 8 CMS Callbridges.

Right now I am struggling with the zone from Expressway C for MS Interop and .space calling to the 8 CMS. The zone can only have 6 peers...

I don't want to use 2 zones with 4 peers, cause of interclustering of the CMS in that case.

Is it possible to add more the 6 peers to a zone via api oder cli? Or any other ideas for that scenario?

Many thanks in advance!

++ You can try using DNS SRV record.

Hi @Mohammed Khan,

many thanks for your reply, but I think SRVs are not an option.

The _sips records are pointing to the CUCM servers at our internal DNS server...

According to Cisco's CMS to Expressway documentation it is not recommended.

See page 22 of this doc: https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/expressway/config_guide/X8-9/CMS-Expressway-Deployment-Guide_X8-9-2.pdf

"Note: Currently, we recommend not to provision multiple peers on the Meeting Server neighbor zone. If multiple peers are provisioned, application sharing will fail during inbound Microsoft AV & Share SIP calls."

On my deployments I've utilized the CLI to script building of multiple zones and search rules to match the zones and simplify the process.
