I have not tried remote lab yet. Thanks to your link I requested access to the lab, but not received it yet. In the meantime I was reading remote lab manual and I found the following information:
"SIP softphones are not controllable through CTI requests"
Also there are no softphones that we use (One-X and Workplace) on the SIP support page
Does it mean that we cannot use our application against softphone with SIP extension logged? Only a SIP desk phone call control can work with our app?
According our developer call control monitor (listener) on the extension works correctly.
We are getting different errors back to our call control requests through DMCC, but as a starting point we focused on the login and
exception. Should we look at different error first?
We are trying to engage Avaya team in help for configuration of our lab, to have it correctly configured for CTI on SIP extensions, but it takes time so I am looking for the root cause also here in the meantime.
My knowledge is poor about the lab config, so I only know that for the used SIP extension COR and COS are set to 1, but I do not know what does it mean now. I will search the answer, but any suggestions for that would be valueable.
