Call PickUp problem

[g.doychev]

Hello,

I have a strange problem related with the function Call PickUp.

First, a few words about the network topology:

- there is a Cisco ISR 2801 with CME 8.0

- there are SCCP and SIP endpoint registered to it

- the same router is a H323 gateway to the ITSP

Now the problem:

When an incoming call is received through the H323 and it is sent to a SIP device, if you try to pickup this call from another SIP endpoint - the pickup fails.

Actually, the first device stops ringing, but the incoming call doesn't connect to the second device.

- there is no problem when the same happens with SCCP endpoints

- there is no problem when the call is local

- there is no problem when the call comes through SIP trunk or FXO

- the call transfer and the others functions works without a problem

I couldn't find a solution for this problem by myself, so any help would be highly apreciated.

If there is something unclear or you need some extra information, please let me know.

Thank you!

Hi,

Can you provide the following debugs

debug voip ccapi inout

PS:rate useful posts!

Attach a "show tech" from the CME.

Here are the tech-support and the debugging output.

The two inside devices are 511 and 512.

Outside caller is 107 and the called number is 512.

511 is trying to pickup the call with FAC **4 plus phone number (512).

Try switching to h323 slow start either at the dial-peer with an h323 voice class or globally under voice service voip -> h323-> call start slow

Unfortunately, it doesn't help.

I can see Cause Code=47.

Can you enable

debug h225 asn1

debug h245 asn1

debug cssip all

debug voip ccapi inout

I saw this too, but coudn't find the reason.

Here is the aditional debuging, that you asked for.
