Dial-Peer help

Unanswered Question
Oct 1st, 2008

Can someone help me with an example dial-peer configuration? I would like to see how to get a call coming in from a SIP VOIP network to get routed out a T1 trunk group. Thanks for the help in advance. Please let me know if I need to provide more info.

now we need to creat an incoming VOIP dial-peer and an OUTgoing POTS dial-peer


the voip take the call from sip VOIP link and the pots route it out through ur T1


dial-peer voice 9 voip

incoming called-number 1234...

codec g711


dial-peer voice 91 pots

destination-pattren 1234...

port [ur t1 port]

forward-digits all

prefix 1234

or what ever diggits change u wanna do

Thank you for the reply,


I have taken your advice and I am still running into the same issue I had previously.


let me try to describe what is going on.


a sip call comes into my 3825 with the dnis 82589.


If I debug dial-peers I can see that it matches the incoming dial peer you had me enter. I can also see that it matches the outgoing dial-peer as well.


The issue is that sometimes the call makes it just fine, but about 60% of the time I get "I'm sorry there are no available lines to complete your call"


Let me paste the relevant entrys from my config:

Marwan ALshawi Thu, 10/02/2008 - 06:34

if the called number come to the router as 82589 matched dial -peer 9 as incoming


the outgoing dial-peer has not port assigned to be send through

u need to add a port


by the way the called number based on the above dialpeer will be send to the pstn as 2589 !


good luck

try it and let me know


sdaniels44 Thu, 10/02/2008 - 06:49

You are quick to respond! thanks!


Sorry, I should let you know that this trunk group is not going to the PSTN but rather a dialer system (Concerto) it expects the DNIS of 2589.


I didn't specify a port, but i did tell it to send it down trunkgroup 1, will this not work properly?



Sorry if I sound like a noob, but I am new to this.

Marwan ALshawi Thu, 10/02/2008 - 06:54

its ok


do u have the cloking between ur router and the system seted up corectly


when u do show isdn status do u have L1 L2 link state as connected or established

sdaniels44 Thu, 10/02/2008 - 06:58

Someone else mentioned that the clocking may be screwed up...


I am not sure how to check this, this trunk is not ISDN PRI.
