[Asterisk-Users] Cisco 7920 and Asterisk - How well do they play together?
Ive read various stories about the Asterisk SCCP implementation. Some say it works fine, others say it doesnt stick with a SIP phone! My dilemma is that Id like a WI-FI phone with multi-line capability, and so far Ciscos 7920 is the only one Ive found. The disadvantage is that it cannot be upgraded to support the SIP-protocol, so if I purchase such a phone I am stuck with the SCCP. Found a table on voip-info.org listing features and whether they were supported in different Asterisk protocols. For skinny and SCCP the corresponding cells only had question marks, so no useful information there. Basically, should I go with the SCCP phone, and what would be the advantages/disadvantages by doing so? If anyone can recommend me a multi-line WI-FI SIP phone with support for encrypted networks, and preferably with built-in network finder, Id also like to hear from you.

[Asterisk-Users] Cisco and protocol application invalid
Hey all! Have configured a Cisco 7960 with no problems, put up an TFTP server and it downloaded new sip binaries all went well. However, now I am having trouble getting two 7040s to work. Basically, my problem is the above stated error message. If I had any entries in the TFTP logfile, I could probably solve this problem. But the thing is, it just doesnt look as if the phones are connecting to TFTP at all. Figured Ill use a packet sniffer to find out which IP-address the phone uses for connecting to a TFTP. That turned out to be rather complicated. First, since I run routers and switches, sniffing packets on the LAN is a hard task. Then I sat up a wireless connection to the internet and onnected the phone to the computer using a shared internet connection, hoping that Windows built-in DHCP server would get the packets flowing. It did, but no packets could tell me which IP-address the phone is trying to reach Is there any way of getting to know which IP address Cisco uses to contact TFTP?

[Asterisk-Users] Silence supression
Hello all! First of all, this is my first post to the list. Ive tried to find my answers in the forums and by Googling , but no luck. My apologies if this question has been answered before. Ive set up an Asterisk box with four local SIP users. The Asterisk box uses a SIP provider for placing external calls and receiving incoming calls as well. In other words, theres no PSTN or ISDN lines attached to the box. Codec in use is G.711 alaw. Ive set up a queue with music-on-hold etc. Sound files are the standard moh mp3s. When I call the queue from local sip clients everything works fine, I hear the music and all seems well. However, if I call from a landline to the asterisk box through the SIP-provider, I can only hear the music whenever I am talking to myself, making some noise etc. I figure it has something to do with silence suppression, but wherever I search I only find information on how to disable this on SIP clients. Since this is a problem that arises somewhere between the SIP provider and the asterisk box, I am lost. Is there any way to get around this in the asterisk configuration, or is it simply that the SIP provider itself is refusing to transmit comfort noice?
