Hi. i am running asterisk 11 and i have a 3g usb dongle to make/receive calls. At the moment the outgoing calls are with the following: ```auto exten => _9X.,1,Dial(Dongle/dongle800/${EXTEN:1},120,KT) exten => _9X.,n,Hangup(${HANGUPCAUSE}) ``` i need to block my caller ID on the outgoing calls and the carrier has the #31# for this to works(it has been checked in an ordinary mobile phone). If i edit the dialplan to be: ```auto exten => _9X.,1,Dial(Dongle/dongle800/#31#ww${EXTEN:1},120,KT) ``` but the carrier responds that the number is wrong. Here is the output from the asterisk’s console: ```auto root@Pbx: /etc/asterisk $ asterisk -rvvv Asterisk 11.25.3, Copyright (C) 1999 - 2013 D == Using SIP RTP TOS bits 184 == Using SIP RTP CoS mark 5 -- Executing [9211123456@AllCalls:1] Goto("SIP/500-00000003", "DefaultPlan,9211123456,1") in new stack -- Goto (DefaultPlan,92105727105,1) -- Executing [9211123456@DefaultPlan:1] Dial("SIP/500-00000003", "Dongle/dongle800/#31#ww211123456,120,KT") in new stack [2018-04-10 13:23:46] WARNING[1327][C-00000003]: channel.c:79 parse_dial_string: Invalid destination '#31#ww211123456' in chan_dongle, only 0123456789*#+ABC allowed [2018-04-10 13:23:46] WARNING[1327][C-00000003]: app_dial.c:2455 dial_exec_full: Unable to create channel of type 'Dongle' (cause 88 - Incompatible destination) == Everyone is busy/congested at this time (1:0/0/1) -- Executing [9211123456@DefaultPlan:2] Hangup("SIP/500-00000003", "88") in new stack == Spawn extension (DefaultPlan, 9211123456, 2) exited non-zero on 'SIP/500-00000003' Pbx*CLI> ``` any ideas please? ---

Previous chan\_dongle questions have established that there is no chan\_dongle experience amongst the regulars on this forum. It is community supported code. ---

Why are you calling with double ‘w’ in your called number? ---

i thought that it might help to add a delay of 0.5 secs for each w. Do you see any way to make it work, please? If i take the ww off, then i have: ```auto [2018-04-11 15:59:55] NOTICE[1172]: chan_sip.c:23797 handle_response_peerpoke: Peer '500' is now Reachable.

During call setup, mobile phone systems don’t send one digit at a time; they send the whole number, in one go, when you press the end key, or do the equivalent electronically. ---

OK, so how do i do that, please? ---

Back to my original response: there is no chan\_dongle expertise here. If removing the w’s doesn’t help, it is unlikely anyone will know what is going wrong, or even if what you want is possible.
