Hi all,

Sorry I don't have the router configs handy but hopefully someone can give me some ideas so I can do a bit of research and fix it myself.

Basically all the IP Phones on the network can dial each other, I can dial out to a PSTN line but can't dial in.

However, looking at the "debug voice dialpeer all" output on the router I can see that when I dial in from an outside line it matches to a dialpeer to begin with but then says it doesn't match at the end of the output.

Any suggestions??

Thanks

Is it POTS or ISDN?

My guess is that it's an FXO POTS port? If so, then you need to use plar to have the FXO ring a phone or set of phones since you cannot DID on an FXO as there is no call setup / sent number during the call only a ring pulse.

If ISDN then do you have Direct Inward Dial configured?

Hi dieselboy,

It's POTS and DID through a trunk to the PSTN. As mentioned above I can dial out to the PSTN but not in from it.

Thanks for your help.

Hi there,
As mentioned DID does not and cannot work with FXO POTS lines. You need to use "connection plar XXXX" where XXXX is the extension you want to ring when the FXO receives a ring pulse from the telco.
Depending on the IOS version, and depending on your setup, the XXXX could be a hunt group for many phones to ring one after the other or in a sequential order.

Under the voice port for the FXO using the above command will make CME answer the line and provide the caller with a ring whilst it tries the extension at XXXX. The downside to this is that if the caller hangs up, the CME does not know they have hung up. On my CUCME system I use "connection plar opx XXXX". What this does is keep the FXO on-hook whilst it tries XXXX. So if the caller hangs up, CME knows this because it will no longer receive the 48V ringing pulse and so your phones will stop ringing too. Without OPX your phones continue to ring for ages after the caller has hung up, which is annoying.

Connection PLAR is easier, but you can do DIDs with translation profiles:

Inbound call to FXO 2/0/0 -> hits inbound dial-p 30 - > translates to ext 222 -> 222 rings

dial-peer voice 30 pots
translation-profile incoming TRANS_IN
incoming called-number .
direct-inward-dial
port 2/0/0

voice translation-rule 222
rule 1 /.*/ /222/

voice translation-profile TRANS_IN
translate called 222

That is still not DID, it's just achieving the same as PLAR. POTS lines do not transmit the number the caller dialed so the system is unable to route calls based on this.

Horses for courses - whatever you feel is better for your system and the people who administer it
