I have a 7914 expansion module which i am trying to connect with ip phone 7962. I have read the release notes for 7962 with 8-5-2-SR1 firmware. It says that it needs to have S00105000400 which i do have on the expansion module.
What happens is when i connect the 7914 module to the AUX port on phone, the phone looses its power. As soon as i disconnect the AUX port, power is back. I tried couple of different 7962 phones. Also I connected the 7914 module to 7960 phone and it works great.
I am thinking of opening a TAC case, but before i wanted to hear from the experts.
