no ring-back from call to pbx (md110) via qsig

Hi,

I have a 2620 router (IOS 12.2(3)) connected to a Ericsson PBX (MD110) with Qsig.

If I make a call to the PBX I don't have a ring-back.

my config is like this;

!

call rsvp-sync

voice call convert-discpi-to-prog

voice rtp send-recv

!

controller E1 1/0

framing NO-CRC4

pri-group timeslots 1-31

!

interface Serial1/0:15

description *** QSIG -> MD110 ***

no ip address

no logging event link-status

isdn switch-type primary-qsig

isdn tei-negotiation first-call

isdn overlap-receiving

isdn incoming-voice voice

isdn T203 30000

isdn T310 60000

isdn bchan-number-order ascending

no cdp enable

!

!

dial-peer voice 100 pots

destination-pattern 6....

progress_ind alert enable 8

progress_ind progress enable 8

progress_ind connect enable 8

direct-inward-dial

port 1/0:15

forward-digits all

!

dial-peer voice 11 voip

destination-pattern 480.....

progress_ind setup enable 3

session target ipv4:172.30.11.99

dtmf-relay h245-alphanumeric

codec g711ulaw

!

I tried anything (also on the PBX) but can't get it working!

What I see in de debug isdn q931 is this;

RX <- ALERTING pd=8

shift to codeset 5

codeset 5 IE 0x32 i=0x81

and then nothing until you pickup the md110-phone.

Does anyone have an idea?

Any help is appreciated.

Thanx :-)

Re: no ring-back from call to pbx (md110) via qsig

We did this in the end at one site

dial-peer voice 440 pots

destination-pattern 440....

progress_ind progress enable 2

direct-inward-dial

port 2/0:15

forward-digits all

I recall the progress indicateor specifies a non-isdn call or the like.
