We have got a strange problem here.
We have CUCM 6.1(2), CUPS 6.0(4) and CUPC 7.0. All CUPC are installed on end-user PCs that are separated by ASA 5500 firewall from CUPS server. As the result CUPC is not working - all different status updates are not going through. As soon as you put the same machines on the same side of the firewall as the CUPS server, everything works perfectly well. We do not use any PAT/NAT and for test purposes we have opened full IP access between CUPS server and CUPC machines VLANs - still no joy, presence updated do not work for CUPC.
Any idea what it might be?
Has anybody tried to implement CUPC 7.0 separated by ASA 5500 from CUPS?
Thanks a lot.
Bug ID CSCsq04749. Fixed in any ASA code after 188.8.131.52 (we are using 184.108.40.206).
We had a similar issue but got it to run by removing the following from our ASA and all remote ASA's that are in our environment.
no inspect h323 h225
no inspect h323 ras
no inspect skinny
no inspect sip
We are running 8.0(4) on the corp ASA and was told sometimes people hit bug CSCsq04749 - CUPC on ASA fails to transmit port 50001 due to reassemble limit of 8192 which is fixed in version 8.0(4.1).
We are thinking of upgrading to asa804-20-k8.bin after talking with TAC.
