Text Push to IP phones not working

[ShankarP]

Hope everyone id safe. Would like to check on push issue. We are trying to send text notification to phone

we are using https://<ipaddress_of_phone>/CGI/Execute method to HTTPS PUSH and sending CISCOIPPhoneText message to push to a IP phone and we are getting an CISCOIPPhoneError = "4" as return 

we have verified the following thing 

.1. The device receiving the notification is associated with the user 

 2. Verified that the username and password is correct 

3. Used authenticate.jsp (url) together with username, password and device name and we are getting "AUTHORIZED" as return 

4. The authentication url is having a domain name in the url string in CUCM parameter and this can be resolved from phone

5. We are able to see the phone status screen when using https://ipaddress of the phone and webpage parameter setting is enabled in CUCM

6. But when trying to browse https://<ipaddress_of_phone>/CGI/Screenshot and provided a correct username and password and still throws CISCOIPPhoneError = "4"

Can anyone please let us what might be possibly wrong. we are running out of ideas what else need to be checked. 

Any help is greatly appreciated.

Does this scenario work if use use HTTP (vs. HTTPS?).
Using the latter is fairly tricky for IP Phone XML services, a few things to consider:
- There are separate secure vs. insecure service URLs configurable for the phones (either in Enterprise or individual phone settings)
- The phones will attempt to validate the server HTTPS certificate when it makes connections - so any external servers that might be in play (e.g. if you have a 3rd party authenticate.jsp server) need to have their certs installed onto CUCM and propagated to the phones (CAPF)
- Examining a network packet capture from the phone's onboard extra switchport might be informative, i.e. to see if there are any network access or SSL hand-shake problems visible.
- If you are still stuck, suggest opening a ticket with DevNet dev support who can provide deeper troubleshooting: https://developer.cisco.com/site/support/

Thanks for the Reply. The issue is resolved.

There seems to be trust (ITL) issue between IP phones and CUCM.
