it turned out that cisco ios sip implementation does not include the new route uri parameters (ftag, lr) that cvs ser adds in its record route entry in the requests (ack, bye, ...) that cisco sends within a dialog. what i heard is that it may take until the end of the year until these bugs get fixed.
thus there is even more reasons to push cisco to get their acts together or find a better sip/pstn gw from some other vendor (so far i haven't heard of any).

I would want Cisco to add the Globalipsound (ilbc) codec to their ASes. we're looking for alternatives until this is done.
The Internet Foundation Austria (which I chair) will likely fund asterisk to include the freeware ilbc codec into the Asterisk IP PBX. We're also funding them to include ENUM lookup in the call processing.
At $1600 per 4 PRI ports card, and a Linux PC around it to power it, this cant be beaten - and it does have a SIP UA (and a server, unsure about this - documentation is fuzzy, gotta read the code). I'm unsure how scalable the thing is; however, at this stage I dont care - yet. And having the SIP code in source at this stage is also very valuable.
this might not be the times for off-the-shelf gateways yet

That depends on what gateway size you are looking for. If that is enterprise, someone told me that VegaStream was doing a good job. I haven't had opportunity yet to get it to our labs.
If anyone has the possibility to get ISDN/analog gateways to our labs, we can allocate cycles to torturing it and sharing how it was doing. I'ld be interested in seeing an alternative.

some people have recommended me asterisk and i downloaded the software yesterday. for asterisk they are selling 4xE1 cards at usd 1495, which is a good deal provided that the cards and the software can do the job.
so far i have had problems with registering asterisk with ser (it seems to always use ip address instead of a name in the host part of uri and i have not been able to give authentication username separately from the uri). also, i haven't been able to figure out, how it could be configured to to forward all calls it gets from the isdn side to ser and wise versa ...
