[cisco-voip] Integration cisco router 2911 with Ericsson pbx

What Dana wrote, plus here's some extra reference:
https://supportforums.cisco.com/docs/DOC-25562

Modify your destination patterns to 84XXXT etc. (or even 84T, 86T, 87T)
Increase T302 timer:

interface serial 0/0/0:15
  isdn overlap-receiving t302 <time in milliseconds>

instruct your users to dial 84XXX, 86XXX, 87XXX (or make sure that the prefixes are forwarded and not dropped on the PBX when dialing out)

However, for dialing in towards the PBX you may want to use a voice translation profile to drop the prefix as the PBX seems to only know of three digit extensions?

Hi Anas,

The debugs show the PBX is using overlap send/ receive. The router has received only one digit and is attempting to route the call but there are no dial-peers to route the digit.

                Calling Party Number i = 0x0181, '803'
                                Plan:ISDN, Type:Unknown
                Called Party Number i = 0xC9, '1'

...

...

Apr  2 09:07:06.190: ISDN Se0/0/0:15 Q931: RX <- INFORMATION pd = 8  callref = 0x0009
                Called Party Number i = 0xC9, '0'
                                Plan:Private, Type:Subscriber(local)

Your dial-peers are 5 digits beginning with 84XXX, 86XXX, and 87XXX.

Check the PABX is sending the correct numbers and you might need to increase the T.302 timers on the ISDN interfaces (int serial 0/0/0:15...)

Cheers
Dana
