Hi All,
Can anyone confirm if ad-hoc group chat is possible between IM&P and skype for businesses federated over expressway?
I don’t think it is. The only doco I can find for federated group chat is for XMPP federation, nothing for SIP, but I can’t find it spelled out anywhere that it is not supported.
I did find a note in the inter-domain federation guide “The IM and Presence Service does not support a three-way IM session (group chat) with a Microsoft OCS contact.” but it’s not clear if that specific to OCS. https://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/cucm/im_presence/interdomain_federation/10_5_1/cup0_b_interdomain-federation-guide-10x.pdf
Cheers,
