Right now I'm try to add the subj feature.
Linksys/SPA2102-3.3.6 (just from the box) respond SIP/2.0 480 Temporarily not available
Landline over Asterisk with E1: SIP/2.0 603 Limit exceeded
Ether I so unlucky, or just forget it and do not provide it to the customers? If so, notes to developers let's take off 408 code processing from sample config.
Thanks in advance for your opinion.
Andrew.
