SIP Phones and SIP trunk on CUCME

[Pawel Lenart]

Hi all,

I have a problem with my system. I have C2801 and 4 phones (2 SIP phones and 2 SCCP phones). I'm trying to configure SIP trunk and SIP phones to work on 1 system so router can work as SIP client (for trunk) and SIP server (for phones) but I can't get it to work. I configured SIP trunk and every phone can phone out without any problem, SIP phones can phone SCCP phones but when I try to phone other SIP phone I can hear ring tone but when I pickup I can't hear anything on caller phone I can hear busy tone. When I try to phone from SCCP phones to SIP phones I can hear then ringing but when I pickup I can't hear anything and after a second I hear busy tone on caller phone. My config:

voice service voip

ip address trusted list

  ipv4 0.0.0.0 0.0.0.0

allow-connections h323 to h323

allow-connections h323 to sip

If anyone needs more config please let me know which part you need.

If using 7912, convert them to SCCP.

Everything will work fine after you do.

[Pawel Lenart]

I use 7912 but I'm doing some testing and I need to get this problem resolved by using SIP phones (In office we have few 9971 which only work with SIP).

first, remove this 2 lines

sip

  bind control source-interface FastEthernet0/1.2  -->

  bind media source-interface FastEthernet0/1.2  -->

second, add this CLI, since all sip INVITE go out to SIP trunk becuase of outbound-proxy

voice register global

  no outbound-proxy

[Pawel Lenart]

Workins as a charm. Thank you very much.

If you dont mind me asking one more question. When I debug CCSIP messages I can see that phones are still trying to go out and register with SIP trunk. Any idea why and how I can turn them off?

did you recreate phone profile?, if not.

voice register global

create profile

reset

or cold start phones.

[Pawel Lenart]

Yes I did but it looks like it wasn't applied after reset. After I erased config from phone it picked up new file and messages looks correctly now. Thank you very much again for your help.

Pawel

Hi Dangsu,

I believe my last message was little premature.

I just checked (next day and router restart later) and SIP numbers are still trying to register with voiptalk. Do you have any suggesttions?

Pawel
