UC520 SIP CLI Missing commands

HI Guys,

Just a very quick one, I had an issues where external calls comming into my UC520 via the Skystone Software was not being dropped into the unity vmail

It took Cisco TAC a couple of days to work this out why....

Apparently there were a couple of lines of CLI missing:

voice service voip

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

allow-connections sip to sip

supplementary-service h450.12

no supplementary-service sip moved-temporarily

no supplementary-service sip refer


no update-callerid

I always use CCA or the skystone automatic configuration whihc enters the following CLI:

dial-peer voice 9999 voip

description Stonevoice SkyStone In-Out

destination-pattern 8[3,4]T

session protocol sipv2

session target ipv4:

incoming called-number .T

dtmf-relay rtp-nte

codec g711ulaw

fax rate 14400

fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback cisco

ip qos dscp cs5 media

ip qos dscp cs4 signaling

no vad

I am no CLI cisco guru, however which system should have entered these commands in should it have been the CCA or the SkyStone Automtatic configurator?

Also I having issues when an external number calls my Skype in number the DTMF tones are not being passed through the cisco for some reason... However on a normal skype call the dtmf tones are being heard...

Any ideas?




Re: UC520 SIP CLI Missing commands

Assume the below CLIs are what you needed to make this work:

no supplementary-service sip moved-temporarily

no supplementary-service sip refer

CCA typically adds the above CLI if you added a SIP trunk provider through CCA. If you did not - then you probably want the Skystone automatic configurator to add the same. Not sure if this directly relates to DTMF
