FXO configuration and dial peers

Basically I have an isdn 30 coming into a cme system and 4 additional analog lines coming in on FXO ports.

Incoming Calls

The numbers coming in on the analogs are all the same number and I have plar'd them to extension 1212, I have four ephone-dn's configured with number 1212 and they are configured with preferences and no huntstop. The idea being that calls coming in on any of the fxo ports will hunt from dn to dn, if the first is busy etc.

Outgoing Calls

All phones have to dial a 9 for an outside line, this takes them out the isdn 30 interface to the pstn, the 1212 numbers I want to go out the FXO ports but still using a 9. So I have created a translation profile which will translate the 9 to a 7, and created different pots dial peers with different preferences out different fxo ports.

I have applied the translation profile at the ephone-dn level is this correct or is there a better way to do this ?

If these extensions dial a 9 then the translation profile should change the 9 to a 7 and route the call out any of the available FXO ports which are not busy. ?

Could someone please verify if I am on the right track with this... ??

Thanks in advance

Re: FXO configuration and dial peers

Hi,

Yes I think you're on the right track. You can configure trunk-group for the 4 fxo lines (and be able to define huntscheme and preferences among them), AND be able to add a less preferenced trunk group in the same DP! (for is you have to promote trunk-gourp the PRI too)

the configuration get smaller and much more readable. Then you have ephone-dn templates that you may like or not to use.

Hope this helps, please rate post if it does!

Re: FXO configuration and dial peers

Thanks paolo,

I tried this but it didnt work, all phones kept going out the pots 9T peer, as a workaround I am having to get users to dial a 7 so it goes out one the analog ports.

I am also having problems with dialling out these fxo ports at the moment, when a user dials a 7 and goes out one of the fxo ports, there is complete silence on the users phone for a considerable amount of time, no noise nothing, before the called number begins to ring, it must be at least 10 seconds or longer before the call begins to ring.

I have tried configuring all aspects of timeouts under the fxo ports with the same results.

Heres a snapshot of the relevant bits.

Re: FXO configuration and dial peers

In addition to the above the timeout interdigit is set to 3 under telephony services.

Anybody have any ides why it takes so long to dial out when dialling out from an ip phone going out an fxo port ?

Appreciate your comments

Thanks in advance

Re: FXO configuration and dial peers

Hi, both things are quite strange. The translation appears to be configured correctly. One should take some debug here to see what's happening.

For the post-dial delay issues, please try entering the number on the phone being on-hook with an # as terminator. Does the call takes less time to complete ?

Another thing that can help, if the UK uses fixed-lenght dialplan (I don't remember now, I had looked on wikipedia and seen that there have been a lot of changes) you can configure some DPs without the T and that will speedup the call for sure.
