Re: Inbound & Outbound VoIP Dial Peers - Page 2

blcase · ‎06-04-2004

Is it possible to have a gateway accept inbound voip dial-peer and send that call out another voip dial-peer? How might that configuration look?

Thanks!

Dear Prasanna,

Are you sure that calls are not even coming to AS?

In fact, maybe calls are coming trough PRI and then tries to dial telco again but telco is giving busy signal to those calls...

example:

1. someone dials PRI number 2720055 and he comes to the AS

2. num-exp or translation rule is applied and now AS dials telco number 160221,,,,1212121212

3. Telco gives busy signal

why?

1. number is really busy

2. number is invalid

3. pause time is not long enough

4. there are some user authentification which needs to be proccesed during a call

...

maybe you can try to debug and see if calls are coming to the AS and are they are going out of AS?

Regards,

Goran

Try this ...

translation-rule 1

rule 0 2720055 160221,,,,12121212

dial-peer voice 2171 pots

incoming called number 217232....

dial-peer voice 2172 pots

destination-pattern 2720055

translate-outgoing called 1

port 1/0/4:d

After you put this in the configuration, make a call and do 'show call hist voice brief' and see what dial-peers the call is matching, as Goran suggested.

Tried but still no movement

1. Were u able to successfully route calls through this gateway ? If yes How ?

2. Did u do PSTN -> IP on this gateway ?

3. R u able to do PSTN -> PSTN using different ports on this gateway ?

I can't see call coming in. Try to do 'debug isdn q931' and see if the call is coming in.

1.This AS 5800 is spcifically for Internet Dial up.

Uptill noe not used for any voice application.

2.No PSTN->IP on this gw

3.On all ports I am able to give ring to any telco no. by reverse telneting a modem from MICA modem pool

I tried to debug isdn q931.Output is :

sh debugging

Dan, you over-simplify things.

Every call going through a Cisco H.323 gateway is matched to both incoming and outgoing dial peers, even if the incoming dial peer is not explicitly defined. And Incoming-Called-Number is only 1 of several matching criteria that can be used.

A simply dial peer scheme can be built without this information. But a complex dial plan will send a person to the funny farm in short order unless these concepts are understood.

happykiran · ‎06-06-2004

Voip - Voip is possible in 3745 ip-ip gateway running 12.3 or later. In other gateways you can only do ip-pstn or pstn-ip.

If you are using either AS5300 or AS5400 the best way to do, as explained by someother responder is to send the incoming ip to pstn and loop it back to another port and send it out as IP.

Another way of doing may be to write a TCL script, though I have not tried it myself, I think it can work.
