I apologize if this is a stupid question, I'm an Avaya voice (cisco data) guy, I'm still learning Cisco voice.
I've installed an analog polycom soundstation 2, I can make internal and external calls. However I can only receive one incoming call at at time (second call receives a busy signal) and I can't conference a second call.
From researching I think I need to change the FXS port from MGCP to SCCP (I have the license for it) but I'm not 100% sure that's correct and if it is I'm not sure how to do it.
Thank you for your quick response, I will without a doubt need the information in the link you provided. Is there any information you can provide that will instruct me on how to change the port to SCCP?
I opened a support case on this issue and they gave me the same information Jorge did. It would have worked if the customer had the DSP resources available. Never thought an analog phone would be such a pain. Ended up setting up a 7937 conference phone.
