SRST/Analog Phone question
	2006-08-30 12:32:48

I'm trying to setup an SRST installation at a location with about 20 IP phones + 3 analog lines. I have a pots line from the phone company to an FXO port both for PSTN access when in survivability mode, and also in general for calls to come in (the number is published). This line is to ring both on the IP phones and also on an analog line. I'm using H323 so I can get callerid from the FXO. I'm having a little difficulty setting up the analog line. I had hoped to just use a 4FXS VIC in the router to handle the analog needs, but I'm running into a problem with it. When a call comes in on the FXO line, i'm sending it out to call manager to ring the line on the IP Phones and also back into the router to ring the FXS line with that number. When this happens and I answer the set on the FXS port, I get fast busy on the calling phone and dead air on the analog set. I set up the FXS ports as H323 enpoints pointing at another loopback interface on the router, this was the only way I could figure to have them act like a shared line with the IP sets but I think this is where I went wrong. Is there a way to get these to ring simultaneously with IP Phones correctly, or should i give up on the FXS ports and use a couple ATAs. -- Ed Leatherman Senior Voice Engineer West Virginia University Telecommunications and Network Operations

Ed, You will need to make your FXS port MGCP controlled by CM. Leave the FXO port as h323. Then either make a shared line between the fxs port and your ipphones or use a linegroup to ring them all concurrently. /Wes Ed Leatherman wrote: mail.gmail.com" type="cite">I'm trying to setup an SRST installation at a location with about 20 IP phones + 3 analog lines.
