PSTN to CUCME

[isaaco001]

Dear Community,

I am able to make calls outside(pstn) using this dial peer below with gsm number.

dial-peer voice 4 pots
destination-pattern 9..........
incoming called-number .
port 0/3/3

I ,however, want calls to be received on a particular directory number  which should be my switchboard.I have seen this kind of configuration done for SKINNY with trunk 9 monitor port 0/3/3 command if this was the case.This configuration is done under ephone-dn and the command is available under ephone-dn command.SIP doesnt have this command under voice register dn.

How do i map outside calls to a particular directory number in SIP without DID number?Is this the correct dial-peer to receive outside calls?

Attached are the full configs.Thank you.

Seems u r trying it on fxo port, if yes..

voice-port 0/3/3
 cptone KE
Connection plar opx <ext number>
 description Safaricom
 caller-id enable

For incoming call through FXO line you can use connection plar command as below to point it to any specific extension.

Yes its an FXO port and the command connection plar opx worked.Now i can make calls from pstn to a particular extension.Thanks you.

However,you must have seen in the configs that i will be using E1 port later.can the command connection plar opx still be used with E1 port?Thank you once again.

[Suresh Hudda]

Nope, you can't use this command on E1 pri. For that you need to apply translation rule/profile.

Suresh

Just to clarify,Will i use translation rule/profile for both incoming calls and outgoing calls or just incoming calls for pstn?.Thanks.

[Suresh Hudda]

It depends, for incoming calls you need to make translation rule for called number to directly connect these calls to extensions. If you want to change CLI for outbound calls ( or want to change isdn plan and type; but this requires only when you need to change them in case of any issue) you need make translation rule for calling numbers, so this is not mandatory.

Hi,i have started configuring E1 connection and i am not conversant with it.However,i followed some instructions and i managed to get this from show isdn status command:

ISDN Serial0/1/0:15 interface
dsl 0, interface ISDN Switchtype = primary-ni
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 0, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0xFFFF7FFF
Number of L2 Discards = 0, L2 Session ID = 2
Total Allocated ISDN CCBs = 0

The multiple_frame_established is a good sign,i think.This is how i configured the E1 controller:

E1 0/1/0 is up.
Applique type is Channelized E1 - balanced
No alarms detected.

Please find full configs attached with dial-peer for E1,I expected outside calls to pstn at  least work without a translation profile.Thank you, please guide.

Please attach debug isdn q931 && debug voip ccapi inout along with called number for a test outbound call. Suresh

[isaaco001]

I will attach debugs tomorrow,please have look at the provider settings attached(screen shots) if they may affect dial-peer operation.Thanks.

[isaaco001]

Please find attached debugs for isdn q931 and voip ccapi inout,i'll keep troubleshooting with given output codes,thanks.

[Suresh Hudda]

You are sending 100 as calling number, can you check with service provider what they are supposed to get in calling number. And please try to change the isdn switch type to something else once and test.

Suresh

[isaaco001]

hi,the service provider calling number should be  07xxxxxx000 ,i have used a translation profile to change any internal extensions like 100  to this number i.e

rule 1 /.*/ /7xxxxxx000/  

However,i still cant make calls to or from pstn,i have tried changing the isdn-switch type but still no success.The isdn switch was set with isdn switch-type  primary-ni as show in the attached screenshots.I am still consulting with the provider,attached are the debugs.Thanks once again.

[Suresh Hudda]

Okay, it is good to check with service provider that why they are sending DISCONNECT message.

Suresh

[isaaco001]

Hi,(update)incoming calls are working fine after i used a translation rule to convert 10 digit number to 3 digit extensions.However,outgoing calls still have an issue,am inquiring from the provider about the issue.I have tried using a translation rule for outgoing calls but still no success and as you stated in the earlier threads,i don;t really need a translation rule for outbound calls right?

[Suresh Hudda · Accepted solution]

Dear, I said it depends. You may need it to change CLI, lSDN plan, type etc if required. What yours service said to about outgoing calling.
