Hi,
 
  Yes, you need two profiles - one for incoming and one for outgoing. I enclose here the relevant fragments from my old config:
 
voice service voip
 qsig decode
 dtmf-interworking rtp-nte    (RFC-2833)
 srtp fallback
 allow-connections sip to sip
 fax protocol t38 ls-redundancy 4 hs-redundancy 2 fallback cisco
Not sure this is relevant:
 
interface Serial0/0/0:15
 no ip address
 encapsulation hdlc
 isdn switch-type primary-qsig
 isdn overlap-receiving
 isdn not-end-to-end 64
 isdn incoming-voice voice
 isdn supp-service name calling profile Network-Extension operation-value-tag local
 isdn negotiate-bchan
 isdn outgoing ie facility
 isdn outgoing ie notify-indicator
 isdn outgoing display-ie
 isdn outgoing ie caller-number
 isdn outgoing ie called-number
 no cdp enable
This is for calls from PSTN to VoIP:

dial-peer voice 201 voip
 destination-pattern 40.....
 progress_ind setup enable 1
 progress_ind progress enable 8
 session protocol sipv2
 session target ipv4:10.1.1.1:5070  Note the special port - it lands on a different profile
 session transport udp
 dtmf-relay sip-notify          Use INFO/NOTIFY instead of RFC-2833
 codec g711alaw
 fax-relay sg3-to-g3
 fax protocol t38 ls-redundancy 4 hs-redundancy 2 fallback cisco
 no vad

The VoIP to PSTN has nothing special:
dial-peer voice 1 pots
 destination-pattern 8T
 progress_ind setup enable 3
 progress_ind progress enable 8
 no digit-strip
 direct-inward-dial
 port 0/0/0:15

To do that I'd have to have another sip profile for inbound call legs on a different port I suppose ?
