Change standard WAP-ports?

Hello.

I just installed Kannel to use it as a WAP-gateway and it works perfectly. My 
only problem is, that my wireless network provider apparently blocks the 
standard WAP-ports at 920x to force everybody to use their gateway. So I 
wanted to change the ports Kannel listens on.

These seem to be hardcoded and my knowledge of the Kannel source-code and the 
WAP-protocol in general is not good enough to decide what to change. A grep 
on the sources show that the binding seems to be in gw/bb_udp.c:

gw/bb_udp.c:    add_service(9200, octstr_get_cstr(interface_name));        /* 
wsp       */
gw/bb_udp.c:    add_service(9201, octstr_get_cstr(interface_name));        /* 
wsp/wtp   */
gw/bb_udp.c:    /* add_service(9202, octstr_get_cstr(interface_name));  * 
wsp/wtls      */
gw/bb_udp.c:    /* add_service(9203, octstr_get_cstr(interface_name));  * 
wsp/wtp/wtls */
gw/bb_udp.c:    /* add_service(9204, octstr_get_cstr(interface_name));  * 
vcard */
gw/bb_udp.c:    /* add_service(9205, octstr_get_cstr(interface_name));  * 
vcal  */
gw/bb_udp.c:    /* add_service(9206, octstr_get_cstr(interface_name));  * 
vcard/wtls */
gw/bb_udp.c:    /* add_service(9207, octstr_get_cstr(interface_name));  * 
vcal/wtls     */

I guess I have to change these. But what about these:

gw/wap_push_ota.h:#define CONNECTED_PORT 9201;
gw/wap_push_ppg.h:    CONNECTIONLESS_SERVPORT = 9200,
gw/wap_push_ppg.h:    CONNECTED_CLIPORT = 9209,
gw/wap_push_ppg.h:    CONNECTED_SERVPORT = 9201
wap/wap.c:#define CONNECTIONLESS_PORT 9200

I couldn't tell from the sources, what they are good for and as I said, my 
knowlege of the WAP-protocol is very limited.

Could you tell me which of these lines I have to change to be able to connect 
to the gateway on a different port, which I specify in my phone? Wouldn't it 
be good to make this configurable over a config-option?

Oh, and I'm using version 1.1.5 as that's the one in the debian archive.

Thanks, Gerrit
