That is not where you add the SRV record. The SRV record needs to be created on DNS. Hostname/iP address nees to be the hostname of your IM and Presence server eg
These names are examples...You should use your domain name
In CUCM documentation I see the next:
Allowed values: Allowed characters include alphanumeric (a-zA-Z0-9), period (.), backslash (\), dash (-), and underscore (_)
So the question is - what the format of dns rsv record in uc profile ?
UC profile does not use SRV records. Jabber utilizes SRV records to discover the presence server. You need to manually specify both IM and Presence server either via DNS or IP address on the UC service
