Problem with call forwarding on 4.3.4

Problem with call forwarding on 4.3.4 when *72+number to transfert is fine but when dialing *73 it does not work.Needed to downgrade on 4.3.3

We will update you asap.



*72 and *73 call forwarding options are working fine with R201 in 4.3.-R8 with asterisk SIP server.  Please check your  sip server configuration.

Please see the Asterisk SIP server configuring for call forwarding features.

Example of Asterisk extensions.conf



exten => 9003,1,Answer()

exten => 9003,2,Dial(SIP/9003,60)

exten => 9003,3,Playback(vm-nobodyavail)

exten => 9003,4,VoiceMail(9003@main)

exten => 9003,5,Hangup()

exten => 9004,1,Answer()

exten => 9004,2,Dial(SIP/9004,60)

exten => 9004,3,Playback(vm-nobodyavail)

exten => 9004,4,VoiceMail(9004@main)

exten => 9004,5,Hangup()


  exten => *72.,1,GotoIf($[${EXTEN:-1} = #]?2:3)

  exten => *72.,2,StripLSD(1)

  exten => *72.,3,DBput(CFIM/${CALLERIDNUM}=${EXTEN:4})

  exten => *72.,4,Hangup

  exten => *73,1,DBdel(CFIM/${CALLERIDNUM})

  exten => *73,2,Hangup

How could it be a sip server misconfiguration when it's working on defferent firmware? Also when dialing *67 for confidential calls it disabled incoming calls (outgoing works only). We need to dial *68 and a number to call to enable/unlock.

Problem with 4.3.4 rolled back to 4.3.2 and fixed the issue.


We are able to see this behavior in our LAB and planning to fix in an upcoming release.

In 4.3.4-R8 image, Call forwarding feature is internally handled by the  R20X device.  Call forwarding (*72) invite messages are forwarded to external  PBX   while activating call forwarding feature but   *73 invite messages are not forwarded by the  R20X device to external PBX.  There is a difference in forwarding configure in r20x device and external PBX.

In 4.3.3 image, by default,  call forwarding feature is disabled in the R20X device so that all Call forwarding (*72 and *73 ) invite messages are forwarded to external  PBX.

Please find the workaround solution:

Add dial rule in 4.3.4-R8 image, In this case,  *73 invite message will be forwarded to external PBX server.




This was not yet fixed in cnPilot-R201P_4.4-R7_201809070815
