Call forwarding failing when dialed from external

[borologio]

Hello,

I'm supporting a client having issues with the call-forward all option.  I'm newly supporting them so I did not perform the initial installation and I'm not sure if this was ever working.  When we setup a phone to forward all calls to an external number it works if we dial it from internally, but when it is dialed from an external number we get a Verizon Wireless message (customer not available at this time).  The number currently configured to forward too is not a wireless or verizon number (however the one phone i'm testing from is).  

It looks like the translation rules are adding digits to incoming numbers (91 - assuming this is for redial purposes).  It appears that the added digits remain when the call is forwarded, i think this is the issue but i'm not sure.  It looks like the number to forward to is being translated properly in debugs.  

Right now we have line 111-222-2807 configured to forward all calls to 913334449067.  When i dial the line from number 3334445774 the forwarding call is directed to 13334449067 but the calling party number being sent to the telco is 913334445774.  i'm not sure if this is the issue or not.  I've attached the running configuration as well as the debugs (q931 and voice translations).  Any help would be greatly appreciated.

Hi.

Can you please send the output of a debug isdn q931 starting from when the call comes in to when VG tries to redirect it?

thanks

Hi Ben.

From your debug, you are forwarding call to a wrong number

Can you please specify what is the final called number that should be called out?

I've changed the numbers in the debugs and in the config to respect our clients privacy.  The phone is configured to forward to 91+10 digits.  The debug shows 1+ 10 digits being sent which I believe is correct.  Also, it works correctly when you dial the phone from another extension, just not when it is dialed from an outside line.  It's this reason that i thought the issue was the translation of the original calling number.  You can see when it first hits the gateway the calling number is represented as 10 digits, however when the call is forwarded the calling number is translated to 91+ 10 digits.

Thanks,

Ben

Hi Ben

Just to have another element.... can you please call the number to where you want to forward calls , from an IP phone and activate a debug isdn q931 during the call?

Thanks

Hi Carlo,

I have a working q931 debug attached now.  This was a successful forward when dialing the extension directly from another phone behind the gateway.

Thanks,

Hello,

I found a solution for this:

Within CME:

Configure / Telephony / Dial Plan / Outgoing

On the Caller ID Tab we changed the Caller Number from "Internal Extensions" to "Any Number"

In CLI:

trunk group ALL_T1E1
 hunt-scheme longest-idle
 translation-profile outgoing PROFILE_ALL_T1E1

voice translation-profile PROFILE_ALL_T1E1
 translate calling 4

voice translation-rule 4
 rule 1 /2809/ /1112222809/
 rule 2 /2801/ /1112222801/
 rule 3 /2802/ /1112222802/
 rule 4 /2803/ /1112222803/
 rule 5 /2804/ /1112222804/
 rule 6 /2805/ /1112222805/
 rule 7 /2806/ /1112222806/
 rule 8 /2807/ /1112222807/
 rule 9 /2808/ /1112222808/
 rule 10 /2810/ /1112222810/
 rule 11 /2811/ /1112222811/
 rule 12 /2812/ /1112222812/
 rule 15 /^....$/ /1112222800/   <---OLD

 rule 15 /^.*$/ /1112222800/     <---NEW
