hi All

i am first time posting on this forum to get help from your experience.
i have installed ism sre 300 on cisco router for CUE, all things working well ,i want to send my voice mails to email id, i was configuring SMTP from GUI of CUE when i give credential and test email id, it gives me error that SMTP HOST NOT AVAILABLE FOR THE EXCHANGE SERVer IP on port 25.
also i can send emails to exhcange server from router but not from CUE?? kindly help on this problem

i will higly appreciate your solution

thanks in advance

Not a CUCM expert by any stretch, but...

a) are you configuring CUE from CLI or GUI?

b) are you specifying SMTP via hostname or IP address?

c) can the CUE and the router resolve the hostname / IP address properly?

d) does the CUE and router have basic layers 1 - 3 connectivity to the SMTP server?

e) from the router, issue a "telnet 25," does it show OPEN?

Start with layers 1 - 3 connectivity, work your way from there.

Regards

i am configuring it from GUI,
i am configuring smtp using ip address of exchange server,
yes my router can send mail to exhcnage server also but not CUE,
yes i can ping SMTP server from Cue and router too and also port 25 is open...

exactt error im getting
could not connect to SMTP server ip address on port 25

How did you come to this conclusion? or did the system generate a message stating this?

yes system generated the following message...

Could not coonect to smtp host ip address on port 25...

From the SMTP server, can you ping the ISM &/or the CUE unit?

Yes its reachable from SMTP server.

Since you said telnet from the router works, do an extended telnet to the SMTP server sourcing it from the ISM interface on the router

telnet x.x.x.x 25 /source-interface ism 0/0

Sorry for late reply.

i have applied this command and output is:
Trying x.x.x.x 25 ... Open
220 domain name.com

421.4.7.0 too many errors on this connection, closing terminal connection

now what you say...

The message '500 5.3.3 Unrecognized command' is actually coming from the exchange server. On the exchange turn on protocol-level logging for the connector that's generating the 500 error. Then refer to the logs for further details of the session failure. Get with your exchange admin to see why the system is spitting out the 500 message. From the Cisco side you may also want to open a TAC case.

Agree with ladino -- basically at this point what you've done is proven layers 1-4 connectivity between the ISM
and the exchange server. Question is what the Exchange server is doing with the request from the ISM.

thanks for your technical concern, it looks problem is on the exchange side and my CUE end configuration is fine...?
well i will update you shortly after meeting with exchange guy and tell him about the logs.
