CME WITH PSTN to CME without PSTN.

i have 2 sites named A and B

Site A has CME and PSTN.

Site B has CME no PSTN.

What I want is to make CME to CME calls and Site B can call PSTN located @ Site A.

Is it by just pointing to SITE A IP address, I will achieve this?

CME WITH PSTN to CME without PSTN.

As suggested by Shrvaran you achive this by using dial peers and pointing to the other CME as session target, you will also need to allow sip or h323 protocol via the following configs:

voice service voip

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

CME WITH PSTN to CME without PSTN.

Hello,

i want to make use of the PSTN @ Site A from Site B. Site B doesnt have PSTN so if Site B want to make outside call it should route it to Site A CME with PSTN.

please reply ASAP if this is achievable.

CME WITH PSTN to CME without PSTN.

Hi

As the shrvaran & chris have shown this CAN be acheived. (+5 )

You need IP connectivity between the sites.

You need to create dial peers and allow the service in voip.

You need to know if you want to use H323 or SIP

So at site "B" say dial a 9 for PSTN access

CME-B

!

dial-peer voice 9 voip

description *** TESTING PSTN H323 DIAL PEER ***

destination-pattern 9T

voice-class codec 1

session target ipv4:172.16.255.11

incoming called-number .

dtmf-relay h245-alphanumeric

ip qos dscp cs3 signaling

no vad

!

CME-A

!

voice service voip

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

Re: CME WITH PSTN to CME without PSTN.

So site A has 3 digit extension's and B has 4 digit..

Is the call from site A reaching the Site B  .Can you see any  q931 logs in B?

New Member

Re: CME WITH PSTN to CME without PSTN.

hello,

note: Site A have the voice-card connected to the pstn but site B did not have it. site B do connect to site A for pstn access.

site A has 3 digit while site B has 4 digit extension number.

site B can call site A but Site A cannot call back to site B.

we are using FXO/FXS port on site A.

through debug command, calls are showing from site A to Site B but after u dial the last 4 digit you get a busy signal tone.

please, what might have cause this and what debug command shud i turn-on on site B to check maybe calls are hitting site B router?

debug isdn 931 IS NOT WORKING.

HELP

Hi ,

sorry 'debug isdn q931' was not the command.

You can use 'debug voice ccapi inout' to check if the calls are hitting site B.

Also you can check if correct dial-peers are matched during the call flow with 'debug voice dialpeer'.

Hi

If you could tell what was the issue...just for informartion

New Member

Re: CME WITH PSTN to CME without PSTN.

Site A is pointing to the SIP server which is

sip-ua

retry register 10

registrar ipv4:209.15.1.1 expires 60

sip-server ipv4:209.15.1.1

!

!

dial-peer voice 1001 voip

translation-profile outgoing profile1

destination-pattern 7T

session protocol sipv2

session target sip-server

Dialing to the sip server is working on site A but Site B needs to connect to site A to dial to the sip server.

Note: Site B does not have a public IP so it need to connect to site A.

What and what do I need to config on site B.

Please reply ASAP. Thanks
