Dial peer order of operation

[Ahmed Awida]

Hi Guys,

I have Vg224 using sccp registered to cucm ,in srst mode i had to create dial-peer with destination pattern to match the number of the fxs port .

Now after cucm returns online the router uses the dial peers with less preference over the dial peer that under stcapp.

when using debug voip dialpeer this obviously show that it matches the less preferenced dial-peer and i can understand the reason that it matched the ANI with destination pattern,but i can't use the in coming called number while the dialpeer is under the stcapp so how to overcome this behaviour ? i changed the dial-peer hunt to use preference first but as i understand if the incoming dialpeer doesnot send the call to call manager then it doesnot matter.

Here is a sample config:

dial-peer voice 20 pots

preference 1

service stcapp

fax rate disable

port 2/0

dial-peer voice 120 pots

description USED IN SRST

preference 2

destination-pattern 101

port 2/0

How to make the calls go to cucm first ?

Help plz.

VG224 SCCP ports can register with SRST GW and there should be no need to add any specific dial-peers, they will work fine with them if your DP assigned to the ports has proper SRST reference and if the SCCP group on the VG224 lists the SRST GW as the last CUCM.

HTH,

Chris

Hi Chris,

what do you mean by ( DP assigned to the ports has proper SRST reference ),how to add the srst reference under the dial peer assigned to the ports ?

(and if the SCCP group on the VG224 lists the SRST GW as the last CUCM.)

i have this configured.

[Chris Deren]

You do this in CUCM, the device pool assigned to the SCCP ports on CUCM have a device pool with SRST reference assigned to it. Then as long as the SCCP group on the VG224 references the SRST as CUCM the phones register natively with SRST and you have no need for any additional dial-peers, etc. 

HTH,

Chris

[Ahmed Awida]

i have this in place too.ok i will remove the additional dial peers and update you now.

[Ahmed Awida]

Now i receive a fast busy tone on the fxs ports after removing the dial peers .

Are the ports registered with the SRST GW?

Chris

[Ahmed Awida]

before i deleted the dialpeers they was getting dial tone but also after using the station-id number command under the voice port

On the srst gateway.

[Chris Deren]

Your PSTN GW should have the normal dial-peers, are you dialing proper digits?

Can you post "debug voice dialpeer" from your PSTN GW and provide the config of that GW.

Chris

[Ahmed Awida]

Chris,i get fast busy signal when the analog phone goes off hook.the debug voip dial peer shows nothing on the gateway

and on the vg224 i get the match of the incoming dialpeer but further digits are not processed cause of the fast busy directly after phone goes off hook.

[Chris Deren]

Can you post your current VG224 config?

This last dialpeer is used in srst mode for sending the call to the srst router,before deleting the dialpeers that you asked me to delete i could make outbound calls but i couldn't call the ip phones interneally which were sharing the dn with the analog phones.

What is the 88888 for? Can you remove it and test again?

deleted it and also got fast busy signal,it was used in my old config as a dial peer that sends the external number to the srst router.

here is the debug voip dialpeer when i goes off hook:
