Digit stripping with dial peer voip

[l.buschi]

Hello,

I have a quescom 200 gsm Gateway and I want to use it with my uc520.

I would like to have call redirected to Quescom if I dial a number with a prefix of 9.

The dial peer correctly forward the call to the quescom gateway but the call fails due to the presence of the 9 digit which is not stripped.

Ho can I do it?

The configuration I made is the following:

dial-peer voice 8000 voip

description SIP Quescom

destination-pattern 9T

session protocol sipv2

session target ipv4:192.168.123.250

incoming called-number .T

dtmf-relay h245-alphanumeric

codec g711ulaw

Thank you very much for your help.

voice translation-rule 9

rule 1 /^9/ //

voice translation-profile strip9

translate called 9

dial-peer voice 8000 voip

translational-profile outgoing strip9

Note most likely you wan a destination pattern like 93........T

That preventing misdialing to domestic cellphone.

very good, it works.

How can I make the calling number appear to my gsm phone?

Also, while my gsm phone is ringing no tone can be heard by my IP phone for almost 10 seconds. Is there a way to change this behaviour?

Thank you very much, very helpfull as usual.

Check the GW settings, probably it has calling identity restricted now.

You heard nothing probably because the GW is sending an alerting message, but no actual progress tones in-band. I suggest you leave you this way, there are a bunch of settings that do not resolve always. If you want to work on this, begin taking "debug isdn q931" and "term mon".

Now I have more information,

I don't know if the could be useful, i try to post them.

As soon as my gsm mobile phone starts ringing i have these situation on dial peer:

Feb 20 16:53:01.166: //-1/C03505CF98B6/DPM/dpMatchPeersCore:

Match Rule=DP_MATCH_DEST; Called Number=9338979abcd

Result=SUCCESS(0)

List of Matched Outgoing Dial-peer(s):

1: Dial-peer Tag=8000

The dial peer 8000 is mached, the phone rings but no dial tone can be heard.

As soon as I can hear a tone I have this new situation on dial peer:

Feb 20 16:55:50.814: //-1/xxxxxxxxxxxx/DPM/dpMatchPeersCore:

Hi, I don't think these debugs are for the same call, are there are 2min 50 secs in between.

Just take debug isdn q931,nothing else is required.
