Cisco SRST - different dial-patterns

Hi ,

 

I have SRST gateway with 2 PRI .

Each of the PRI connected to different provider.

SRST configured with SIP protocol ,Each of the PRI has a different DID.

 

voice register global 

 defualt mode

 no allow-hash-in-dn

 max-dn 600

 max-pool 500

 dialplan-pattern 1 6834... extension-lenght 4

 dialplan-pattern 2 683454... extension-lenght 4

 

when calling to 6834... it's works properly, when calling to 683454... it's not working.
If I will change the configuration that 683454... will be "dialplan-pattern 1" it's will work propely but 6834... isn't.

 

Any suggest?

Re: Cisco SRST - different dial-patterns

Try the following

dialplan-pattern 1 6834[0-4].. extension-lenght 4

dialplan-pattern 2 6834[6-9].. extension-lenght 4

dialplan-pattern 3 683454... extension-lenght 4

Re: Cisco SRST - different dial-patterns

Hi ,

Thank you for your response.

 

I was wrong.
DID 1 is 6404...

DID 2 is 733294...

 

voice register global 

 defualt mode

 no allow-hash-in-dn

 max-dn 600

 max-pool 500

 dialplan-pattern 1 6404... extension-lenght 4

 dialplan-pattern 2 733294... extension-lenght 4

 

when calling to 6404... it's works properly, when calling to 733294... it's not working.
If I will change the configuration that 733294... will be "dialplan-pattern 1" it's will work propely but 6404... isn't.

Re: Cisco SRST - different dial-patterns

Check the command show dialpeer voice summary. For each extension you
should see 3 dialpeers. For example, extension 4001, you should see the
following dialpeers

4001$
6404001$
733294001$

Re: Cisco SRST - different dial-patterns

Hi,

The issue is with incoming calls from PSTN to Phone registered to SRST when the second dialplan-pattern not match, just dialplan-pattern 1 match.

 

attached is "show dial-peer voice sammery"

Re: Cisco SRST - different dial-patterns

Your dialplan-pattern 2 is 733294... and your dial-peer voice 30 is 73329....

I wonder if making them match would solve the problem. Spitballing here...

Re: Cisco SRST - different dial-patterns

Hi ,

Thanks for your response .
It's not the issue , if I will configure the dialplan-pattern 1 for 733294.. it's will work .

The issue is that the second dialplan-pattern (2) isn't work no matter what I define.

Re: Cisco SRST - different dial-patterns

Can you try it using voice translation-rule instead of using dialplan-pattern? Here is the configuration:

!
voice translation-rule 1
 rule 1 /^640\(4...\)$/ /\1/
!
voice translation-rule 2
 rule 1 /^73329\(4...\)$/ /\1/
!
voice translation-profile PRI1-PSTN-IN
 translate called 1
!
voice translation-profile PRI2-PSTN-IN
 translate called 2
!
dial-peer voice 9001 pots
 description # Incoming Calls on PRI-1 #
 translation-profile incoming PRI1-PSTN-IN
 incoming called-number 6404...
 direct-inward-dial
 port 0/0/1:23 --------------------------------------> Change PRI Port number according to your setup. 
!
dial-peer voice 9002 pots
 description # Incoming Calls on PRI-2 #
 translation-profile incoming PRI2-PSTN-IN
 incoming called-number 733294...
 direct-inward-dial
 port 0/0/2:23 --------------------------------------> Change PRI Port number according to your setup.

Re: Cisco SRST - different dial-patterns

Hi ,
Thanks for your response.

This configuration working in SRST mode , but i have a problem to configure it because incoming calls which route to CUCM needs to forward all the pattern include 6404... (the cucm discard digits) and if i will configure the below dial-peer 9001 will match and discard the first three digits and i can't forward just 4 digits to CUCM because i have a lot a manipulations on CUCM.

In SRST mode i need to forward 4 digit using dialpeer pots.

In CUCM mode i need to forward digit all using dialpeer voip.


Thanks,

Danielo.

Re: Cisco SRST - different dial-patterns

Hi,

Do you just want to forward 6404... to CUCM or you want to forward both 6404... and 733294...?

Re: Cisco SRST - different dial-patterns

What protocol are you using between SRST Router and CUCM for PRI lines?

Re: Cisco SRST - different dial-patterns

Hi,

CUCM mode:

Provider-> E1 PRI -> VGW -> SIP -> CUCM ->sip ip phone 

 

SRST mode:

Provider -> E1 PRI -> VGW -> sip ip phone. 

 

Thanks, 

Danielo.

Re: Cisco SRST - different dial-patterns

I am assuming that you have unique 4-digit numbers in DID range 6404... and 733294... for example 6404[1-4]XX and 733294[5-8]XX; then here is the configuration you can try for non-SRST and SRST mode:

!
voice class codec 1
codec preference 1 g711ulaw
codec preference 2 g729r8

During normal operation, the dial-peer 1001 will be used to prefix the digits and send the calls to CUCM. During SRST mode, the IP Phones will register to SRST router with 4-digit DN and it will create dial peers automatically.

Re: Cisco SRST - different dial-patterns

I think dialpeer 30 is matched before dial-pattern. SIP registered dns will
have dialpeers from 4000xx which won't be matched with your dialpeer 30 in
place.
