Vik,
I am trying to confirm if VPIM/IP can and/or should be used for Unity & CUE networking: I am getting mixed messages on the topic. I saw that you already answered another forum question on the matter and stated that you can do this, but the below 2 links (currently on CCO and other places I look indicated that you cannot or at least should not use this method for Unity to CUE networking: http://www.cisco.com/en/US/partner/docs/voice_ip_comm/unity_exp/rel2_0/c onfig_ex/cuexip.html The example cited utilizes 4 IOS Gateways with NM-CUE/across 4 WAN connections http://www.cisco.com/en/US/partner/docs/voice_ip_comm/unity_exp/rel2_0/c onfig_ex/cuexdns.html The example site utilizes one IOS Voice gateway and 1 Cisco Unity server over WAN I found another snippet on restrictions (although it's from an older doc) below: Limitations and Restrictions The following considerations apply to the setting up of VPIM networking between Cisco Unity Express and Cisco Unity: Each location ID (dial ID) must contain at least three digits. Network addressing must be done through DNS (in other words, with hostnames). Direct IP addresses can be used for networking between Cisco Unity Express sites, but they cannot be used if any of the sites in the network are Cisco Unity systems. If network broadcast messaging is used, the VPIM broadcast ID on Cisco Unity Express must be configured to be numeric only. The default string (vpim-broadcast) is alphanumeric and cannot be used to network with Cisco Unity. Cisco Unity Express allows configuration of up to 500 sites (one local and up to 499 remote). A redirect server (such as sendmail) can technically be used to redirect SMTP messages for VPIM networking between Cisco Unity Express and Cisco Unity, but this is an untested and unsupported configuration. Each domain suffix must be unique within the Cisco Unity Express and Cisco Unity sites. For example, naming the sites cue4.cisco.com, cue6.cisco.com, and unity.cisco.com does not work, because the suffix for all sites is cisco.com. Instead use a scheme such as cue4.cue.cisco.com, cue6.cue.cisco.com, and unity.unity.cisco.com. This scheme distinguishes between the cue.cisco.com and unity.cisco.com domains. I am asking for your clarification/guidance on the 2 questions below: 1. Is networking Unity and CUE via the VPIM/IP method supported ? 2. Do you have any additional context or guidance on the matter? Thanks Mike From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of Azeem M.

I got it one-way working from CUE to HQ but not the other way around. Thanks.
