A while ago, I started looking at Sip Express Router, as a proxy for my company’s VoIP platform. After a little searching and reading, we found that there wasn’t any LDAP support available by default. When we contacted IPtel, they told us we could ‘buy’ a module they wrote for another customer, that did just that. Unfortunately, we did not have the budget back then, and started coding on our own.

You can find the result here. It gets the job done, at least for us. Please do mind that it is not based on what IPTel can offer/is offering, and I doubt it has identical functionality. (For example, ‘my’ module requires both MySQL and LDAP, instead of putting the usrlocdb into LDAP).

Anyway, feel free to check it out, and let me know if it works (or does not work) for you ! :)
