I have an issue with Jabber whereby I can log in to Jabber on iPhone via WiFi (e.g. hotel, at work) but not at home. I get an error "Cannot recognise your service domain". Does anyone know why I would only have this issue at home (where I need to do most of my video calls)? Thanks

Sounds like a DNS issue
Open a command prompt on your computer
Type
nslookup
set type=srv
_collab-edge._tls.[your jabber domain] (i.e. _collab-edge._tls.cisco.com)
It should resolve to your Expressway's address. If you get a non-existent domain error it is a DNS issue.
Now try forcing Google's DNS
Type
server 8.8.8.8
Run the command again
_collab-edge._tls.[your jabber domain] (i.e. _collab-edge._tls.cisco.com)
Verify that it resolves now. If it does, modify the DNS in your router to one like Google and try again. You can also manually force a DNS in your Wifi settings on your iPhone

So are you using Jabber Mobile? or are you using Jabber through a VPN?
cheers
Please rate if useful.

Could be your home WIFI router isn't set up to forward the traffic back to your device properly.

this issue looks like a DNS because cannot recognize service domain means your jabber client is not hitting Expressway-e-server.
check in command prompt below commands.
C:\Users\sushants>nslookup
vcse.domain.com (use your domain name)
( it will show your public Ip)
Name: vcse.domain.com
Address: X.X.X.X
then check srv records :
> set type=srv
> _collab-edge._tls.domain.com
it will show you 8843 port and be pointing to your expressway-server
( if you are not able to resolve mentioned a and SRV records change your DNS setting manually and add global DNS server 8.8.8.8 and try again jabber will work .)

check your SRV records and see if they can be resolved through your home network
